Is this why my analog rig isn't so hot?


Hi All,

My system is quite decent, but...

Could it be the voltage output of my Benz Glider is too high?

My photo stage - a 47 Lab PhonoCube - could handle low outputs down to 0.12 mV. Since my Glider has a medium output (0.83 mV) - is this why I'm not that happy with my system? I seem to want to hear more, specially the top.

If I got the same Glider but with a lower output, would it make a difference? Or should I get a better cartridge? And which one?

My system:

Basis 2000 table
RS-A1 Lab arm
Benz Glider (0.83 mV)
47 Lab PhonoCube phono stage
47 Lab Chooser passive preamp
47 Lab Gaincard amp
Konus Audio Essence speakers

Thanks!
George

Raul,
What's the difference between static compliance and dynamic compliance value? some cartridge company gives you static compliance and some dynamic compliance. What does all this mean? I just know that my cartidge is a high compliance according to the manufacutres website and from professional reviewers.
George, with your system as it stands, how much can you turn up the vol pot on your passive pre? 8 o'clock? 9 o'clock? 12 o'clock?

Compare this when playing CDs and LPs.

Also what cables are you using between the source (phono/CD) and your preamp?
I don't think making sure the loading is correct in the phonocube is wasting time. You already have all the equipment George, you might as well make sure you've got it properly dialed in... how else can you make a reasonable decision about the sound of your rig? You'd have to do the same with another TT anyway...
Quite a fascinating conversation, George is certainly getting an earful. If I were in his position, I would certainly explore all reasonable no-cost or low-cost solutions before dumping my whole rig and starting over.

I'm not saying Ken is wrong about the Basis. I've never heard one as I mentioned, but I'm no fan of acrylic tables and I have no trouble believing that adding the suspension could impair clean, strong bass response. I've written about the theoretical danger of that several times. OTOH, I've never heard anyone call the Basis bearing "loose". I thought it had a rep for being one of the best. ??

Ken,
You didn't say why you'd avoid Clearaudio or Teres or make any model distinctions. Why the blanket slams? How about some specifics. What have you heard?

In the case of Clearaudio I suppose it might be the acrylic thing again, but what are your objections to Teres? With the exception of the one person already mentioned by Dan_ed, the response of every Teres hearer has been positive. In side-by-sides with Linn, Basis, Clearaudio and Nottingham a comparably priced Teres has usually come out on top. I don't know of anyone who's A/B'd a Linn vs. a Teres and preferred the Linn.

I can tell you for certain that the two Teres rigs I've heard have snapping dynamics, unlimited HF response and clarity, and clean bass to well below 20Hz. (Mine plays cleanly down to at least 16Hz, the lowest I can hear, and I suspect larger models would do even better.) As Dan_Ed said, proper support is vital, as are a suitably matched arm, cartridge and phono stage.

Which gets us back to George's problem...
Hi Doug,

>>Mine plays cleanly down to at least 16Hz, the lowest I can hear, and I suspect larger models would do even better.<<

I find this statement bewildering, I wonder how you could hear and then measure this low from vinyl, and clean bass to boot. Let's forget that analog never went that low (33-34hz max) and that most analog recordings are in the +40hz range, what I don't see is how your system could even approach 16hz. The 803 Nautilus at best is capable of 60hz-70hz of real bass and anything below isn't really natural bass. Yes, I'm sure you get some boom boom below that but even B&W doesn't claim 16hz.

I SERIOUSLY want to know how do you get clean bass down to 16hz!

>>I've never heard one as I mentioned, but I'm no fan of acrylic tables and I have no trouble believing that adding the suspension could impair clean, strong bass response.<<

I did mention upper bass hump of Basis suspended tables but it doesn't mean that all suspension is evil. Take the Goldmund Reference for example, its one of the finest tts ever made and its suspended. Regarding acrylic, most Teres tables are also fully or part acrylic, I'm not saying that I like them but you do! High quality acrylic isn't all bad if used correctly, the Reference's platter is a sandwich of metal and acrylic but it doesn't have any of the sonic defects associated with this material today. I agree with acrylic's coloration when it comes to many popular tables these days. Its probably because they use acrylic for cheapness of design and production rather than anything else.

>>I've never heard anyone call the Basis bearing "loose"<<

I said that because the bearings are loose. Please go and play with one of their tables and you'll see what I mean. People are buying up these things and never questioning their quality due to lack of experience or because of some review. There's no mystery here, pick one up in your hand and judge it like you would any other object costing thousands. Ignoring the brand propaganda could you pay that much money for anything else made this way?

Here I must concur with Ken that there are other brands with the same faults. What I disagree with is his blanket dismissal of high mass tables, again its all a question of design and implementation. Some of the best turntables ever made have all been high mass units.
