Stereophile confirms new gear is getting worse....

It appears that "high end" audio gear is moving backwards rather than forwards. If you doubt this, take a look at the November 2003 issue and the test results of the electronics reviewed.

As a case in point, the Pass XA160 mono-block amps that were reviewed perform pretty horribly. While most folks that read these forums know that i'm not shy about being a fan of Nelson Pass' work, i don't have much good to say about these over-priced boat anchors. Most will probably remember what a hard time that i gave the PS Audio HCA-2. In effect, most of the comments that i made about that amp apply to this amp. From what i can tell, the comments that i made about the PS may not be strong enough as compared to how poorly the XA160's performed, especially at the price. Lack of current output, high distortion figures, non-linear frequency responses, the ability for the loudspeaker to modulate the output of the amp, etc... were all evident in the test results. To top it off, the input and output impedances will make this unit quite sensitive to the components ( preamp, speakers, etc...) that it is mated with.

Regardless of who's name is on this unit, how "pretty" it looks ( gorgeous ), what it weighs (200 lbs per monoblock) and the parts quality inside, quite honestly, this unit performed like a really crappy "vintage" ( read that as "low tech" ) tubed unit from the days prior to audio civilization. All this "eye candy" and a sore back for only $18K a pair !!!

As we move to the next product review, we look at the BAT VK-51SE. While this unit was more consistent than the Pass, some of the design choices made are obviously not good ones. The most obvious flaw that i see with this unit is that it changes sound / tonal balance as the volume is varied. Even when the gain control is adjusted for the flattest response, the top end starts sloping off gradually above 5 KHz. As you increase the gain, you now introduce low frequency roll-off into the equation also. If really standing on the throttle, the unit doesn't even make it down to 100 Hz within a -3 dB tolerance window !!! Obviously, this is not very good or linear and is poorer performance than one would expect out of a "reasonable" pair of speakers, NOT line level components !!!

As such, you can't expect consistent sonics from this unit unless you listen at one gain setting. If you have only one source component and all your recordings are of the same intensity, you "might" be able to find a reasonable setting. Since i highly doubt that this is the case, especially the part about consistent volume from recording to recording, you can pretty much count this out.

On top of the variations that this unit produces on its' own, one can introduce a whole new gang of variables into the equation once you start factoring in input / output impedances into the equation. I'll just say that this unit isn't going to be very versatile in terms of what components it mates up with in terms of amp selection. All this "high tech performance" for only $8500. Make that $9000 if you want the convenience of a remote.

Moving a few pages further, we run into the "giant killer" AH! Njoe Tjoeb ( pronounced "new tube" ) 4000 cd player. This is a highly modified / hot-rodded Marantz unit with tubes added, a "super clock" and the option of a "plug & play" upsampling board, fancy footers and an upgraded power cord. Depending on what you want to spend, the base unit is $700. If you go for the unit fully loaded with options, you can feel your bank account drained to the tune of about $1200.

Take one look at the frequency response of this unit and you'll see that it is far from "neutral". To top it off, distortions are higher along with a lack of suppression of AC harmonics. Jitter is pretty high for a unit with a "superclock" i.e. higher than other units i've seen with no "superclock". As such, this unit doesn't appear to be a "killer" of any type other than being able to "flatten your wallet in one swift motion".

Obviously, "high end" has come full circle. That is, it would appear that "audiophiles" are more concerned with asthaetics and reputation than actual performance and fidelity. The folks that used to laugh at Bang & Olufsen are now falling for looks at an even higher price. While the sonics may differ from Bang & Olufsen, the end result is that none of these units are "accurate" or capable of being called "high fidelity" units any more than Bang & Olufsen gear of yester-year was. The fact that B&O are now trying to jump back into "high end" with some truly innovative products just goes to show that one can't judge a company or product by its' cover any more.

Having said that, the above mentioned products can't really be called "Hi-Fi components". What they can be called are "flavoured audiophile toys". The funny thing is that J. Gordon Holt had commented on this type of situation arising within the industry and there are letters in this issue agreeing with that point of view. J. Peter Moncrieff also talked about that in IAR Hotline 76-80 quite a while back and found it rather pathetic. Count me in with that crowd too.

I do have to credit JA and the guys for having the guts to print these test results. While there is plenty of "dancing" in all of the reviews along with more than enough "gushing" ( the Pass review in specific ), it was pretty obvious that JA really DID make mention of the technical problems that each of these products displayed. As usual, Stereophile remains consistent in the fact that they continue to test, measure and display the results for all to see. For this, i offer a very hardy pat on the back, vigorous hand-clapping and whistling. THANK YOU from all of us that like reading and interpreting spec's for ourselves. Having said that, JA still tried to down-play these flaws somewhat by giving the "old soft shoe" at the end of his technical comments.

As i've said before, one has to buy and use what they like and makes them happy. With all of the various and BLATANT "flavouring" that is going on with audio gear nowadays, one really must know what they want and how well components will blend together in their system. It would appear that the days of trying to achieve "accuracy" and "musicality" with with each piece of gear are over. Now audio is kind of like Baskin-Robbins i.e. you've got to know what you like before you order what are VERY specific "flavours" for each product selected.

Let the buyer beware.... Sean

PS... I've got my flame repellent armour on along with an oxygen tank and a full battery of weapons. After this post and the responses that i think i'll get, i know that i'll need all of that and maybe more : )

To all of our supporters, acquaintances, friends and others in the audiophile community:

Recently Stereophile reviewed a pair of XA 160 amplifiers that are rated at 160 watts per channel into 8 ohms. In spite of what we consider to be a rave review, they did not meet their full power spec. Unfortunately, we did not hear about this until after the review. Although their policy is to inform a manufacturer of such a discrepancy, this didn't happen, so it was a bit of a surprise.

When we received the amplifiers back, we did indeed confirm the wattage shortfall, which was due to maladjustment. This was easily corrected, and the amps do indeed measure 160 watts.

How does something like this happen? Tracking it back, this particular pair was taken home for subjective listening and they did not receive a final test.

Does this alter the "tone" of the review with regard to the sound? We say only to the extent that they possibly sound a bit better, having a little more power, slightly lower distortion, and slightly higher damping factor.

Do the US owners have reason for concern? NO. First, such a maladjustment does not have an effect on reliability and only a slight effect on the sound. A customer concerned that his XA 160's might not meet power spec can arrange to have the units examined at the factory and readjusted if necessary without cost, and Pass Pabs will pay the freight both ways. This offer will extend indefinitely to the XA 160's from the first units made to those shipped through September 2003.

Like any other human endeavor, mistakes do happen, and we feel the measure of a company is in its response to the customer. As always, we do our best to insure customer satisfaction.

Respectfully,

Peter Perkins, domestic sales, Pass Labs

Unsound, I don't quite follow your logic. I guess I would agree with you, I just don't see how that differs from what I said. It is all an act of expression. That could be an expression of perceived accuracy or simply something different and pleasant.

Sean, sounds like fun with all the systems. I truly am jealous. Is it new gear or old gear? And if they all sound different which one is more correct? Logically, if we are pursuing accuracy there are clearly systems that are "right" and systems that are "wrong". Taking that a step further, If you have 5 systems that all sound differently that means that, at the very least, you have 4 "wrong" systems. The fact that you are keeping them around tells me that you enjoy, at least some of the time, inaccuracy. I also have a "wrong" system. But I have a "good" system (for me) and I bet you have 5 "good" (maybe "great") sytems for you.

As far as attending live music shows...good for you. Again, that statement was not directed at you personally, just audiophiles as a whole.

When I talk about live music and knowing how an instrument generally sounds, I am not talking about amplified music in some large venue. That is the very epitome of inaccuracy. Worse everything than we all have at home plus distortion. If we want to compare our systems to that then nearly everyone here has far more accurate systems than what is heard at these venues. To hear accuracy you need to hear an unamplified instrument. Generally, to hear an unamplified instrument you need to be playing it. To KNOW accuracy (unless you are extraordinarily gifted) you need enormous experience playing.

Finally, since I feel I'm getting off track with Sean's original post... Without knowing 1/100th of what you do in your area of expertise, based on what you say, I agree with you that those particular components seem to be trying to pull the wool over our eyes. Maybe they sound great, or maybe they sound like crap, but it doesn't seem likely that they would be pushing the limits of accuracy if, in fact, that's what they were trying to accomplish.

Zaikesman, I really like how you phrased that, "live acoustic music can never really be accused of sounding overly bright or etched: it is what it is." I completely agree. I was not very clear in my previous statement. I meant acoustic and should have specified that. I used those terms as they seem to be defined by audiophiles. A lot of what I hear accused of being bright I find to be more accurate than something accused of being "neutral" (I do, however, prefer the "neutral" or "warm" sounding equipment). Live acoustic music, "Is what it is" I was just pointing out that, in audiophilese, it is generally bright (while the bass can sound fat).

Also, I have never set up a tubed system. I am embarking on my first, but I have had the pleasure of listening to some and generally like what I hear. However, going back to my assertion that live music is "bright" and tubes are always described as "warm", clearly this is not a match.

Lastly, I am talking about the sound of an instrument, you are talking about the sound that instrument makes through and amp and out a speaker. These are two completely different things. Granted, if you play electric, there isn't much of a sound without the amp and speaker. I don't play guitar much so I don't have much experience comparing tube and SS amps. But you talk about the pleasing distortion of a tube amp, then call SS dead and lifeless. Perhaps dead and lifeless is more accurate? I have no idea in this case--I simply don't have the experience. You appear to have chosen a sound that is pleasing to you and attached the label "accurate" to it. Then you dismiss SS for not sounding like it, therefore it's inaccurate. THIS IS NOT A SS vs. TUBE COMMENT!!! I'm just pointing out a flaw in the collective audiphile logic. We all speak of accuracy, but we are all talking about different things; usually we are simply (perhaps unknowingly) referring to a particular sound that we like.

And I can't stop now without getting this off of my chest. Assuming one knows what accurate is, the second that individual invokes vocabulary words like: warm, bright, etched, rolled of highs, lack of lower octaves etc. you have automatically identified that component (or chain of components) as inaccurate. An accurate component "is what it is". There would be no description.

True and False statements (amplification gear):

. 'New gear is getting worse'
*False*

. 'Some of the new gear is getting worse, especially if we consider the Quality/Price ratio. Example: Pass Labs.'
*True*

. 'Most of the new gear is getting much better, either by achieving unprecedent and exceptional results (example: Pathos Acoustics); or by getting previous results, but at a much lower cost (example: NAD)'.
*True*

. Stereophile is one of the best 10 hi-fi magazines in the all world.
*False*

Kind regards

From reading some of the above posts, it seems that certain people are under the illusion that modern recordings are a faithful transpcription of a real event. With few exception, nothing could be further from the truth. Modern recordings have more in common with Hollywood style films. Both are skillfuly crafted, totally artificial constructs intended to simulate an idealized reality. When Julia Roberts gets a close up in her latest release behind her and completely out of the visual image are 100s of technicians making sure the image is picture perfect. It's the same thing in modern recordings except instead of 100s there are only dozens of techs.
