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 : )

Good post. It invites stimulated , diverse opinions and has stayed civil. Its why I continue to visit this site daily. Kudos for having the nerve to invite such wrath . I would like to see a special dedicated forum on a weekly basis between any given two AG vets such as Sean and Zaikesman or say albertporter and tok20000 just to name a couple that display spirited and constructive debate about a particular subject the two disagree on. Occasionally these posts become mini think tank extrapolations of often misunderstood audio principles. I personally would pay to see these " clash of the audio titans" .
Sean, I disagree that components are getting worse, but I totally agree that many high end components are actually expensive sonically flavored toys. There has never been a greater number of well built, good sounding, reasonably priced components as there is now. Unfortunately, sonic accuracy seems to be taking a beating in higher end products. People are seemingly pursuing musicality over strictly accurate reproduction. It's not unusual on Audiogon for accuracy to be used in a perjoritive sense. While a good system should not deconstruct music down to its bare elements, neither sould the pursuit of musicality ignore the fact that components must first accurately reproduce the input signal fed into it. If you divorce audio reproduction from accuracy you end up with audiophile systems that are put together to simply make one's records sound "good". Sounding good and being accurate should be the goals of true music loving audiophiles.
I think a couple of issues about specs hasn't been properly addressed. Are the specs produced from proper testing procedure? Lets give them the benefit of the doubt even though I've always had trouble with Stereophiles quite frank admission about room anomolies, microphone placement issues and speaker measurments that consistently seemed to produce like errors. It seems as though many have taken a leap of faith that the specs and their deviation from what might be considered standard expectations were designed in. Is it possible that there might just be a bigger issue with quality control in the high end? I suspect that it might be a lot of both.
I also think it would be interesting for a manufacturer to step forward bravely and allow JA or others to test a piece of equipment, say 10 of 100 that were built, and those 10 represent the beginning, middle and end of the build run. Then plot the findings as a statistical analysis showing the standard deviation within the build run. That way we would get to see what variations can occur between units built to a particular spec. It would be a huge risk to agree to but could also be an important reward for such a participating manufacturer. So many times in Stereophile we have seen the review sample returned to the manufacturer for "problems" and a replacement sent back that was analysed and listened to that sounded and spec'd better.
Onhwy61 makes what I suspect is a very valid point about evolving audiophile perceptions regarding the desirability of 'accuracy'. It is of course not a new observation, and whether it's one that is causally, or only tangetially, related to the point of Sean's original post is open to debate. But I don't want to come across, with my above statements supporting individual preference and the marketplace, as seeming to be totally cavalier about this legitimate issue.

I would generally support the contention that during hi-fi's 'golden age' - despite the state of the art then not being as 'accurate' as is possible today (yeah I know, some would argue that point...) - the *goal* of achieving literal 'high fidelity' to the signal encoded on the recording medium was more enthusiastically embraced by the audio community as being the Platonic ideal the hobby ultimately aspired to. Today, it does sometimes seem that such an ideal is currently regarded, by at least a sizeable proportion of self-described audiophiles, as being distinctly subordinate - if not outright antithetical - to the goal of pursuing the 'Absolute Sound'.

Although I'm all for the recreation of the 'Absolute Sound' as our overarching dream for in-home music reproduction, it is alas an essentially impossible one. As I see it, the problem in attempting to simulate such a perception through the introduction of deliberate non-linearities into the replay system is that such an approach devalues and is often in direct conflict with the necessary (and uncontrollable by the listener) imperatives represented by the signal that is recorded on the software. To me, we *should* be pretty much completely dependent on the recording and software to capture and encode that 'Absolute Sound', and call upon the replay system only to try and transmit that as best we can. But by the same token, it is hard to argue with the position that our replay systems will *always* be non-linear - and in significantly arbitrary fashion (and the same goes for recording systems) - so *why not* attempt to tailor the reproduced sound to render recordings (some, if not all) in the most subjectively pleasing light? After all, isn't this hobby all about personal enjoyment?

Well, yes it is - but: I personally cannot fully enjoy music reproduction that I consider - or the evidence shows (and such evidence could be measured, OR HEARD, and maybe not able to be measured) - to strive for something other than hewing fairly closely to the ideal of 'accurate' reconstruction of the recorded signal. But I realize that's just my preference. I think it's a logical preference, one that I'm most comfortable with, but not one that's shared by all audiophiles. So I'm not going to get upset when gear manufacturers make gear for that segment of our market which has had enough of the pursuit of 'accuracy' and gets more pleasure out of trying create a convincing and pleasing illusion with their systems, even if they know that might deviate from what's strictly on the disk, and despite the problems I myself find with this type of philosophy. In an imperfect world we have to pick our poisons, and if the marketplace didn't naturally dictate that diversity was the right solution, then we wouldn't have the proliferation of firms in this business that we do. I for one can gracefully accept that fact, and still keep my opinions.
