    What a quiet, classy guy. I was the only one in the room with him for about ten minutes. Dan was kind enough to answer my questions without bravado. But mostly he sat back and listening like a proud father.

    Blasphemy Fred, complete Blasphemy!!! :razz::lol:

    Can't say for sure as I haven't seen that one in person. I rather like them on the X and XA series. I think I actually like what they represent more.

    Thanks for posting that. It reminded me that I needed to get the 3rd party VUs for my Touch, since I think the built-in ones are so ugly. In fact, I prefer the VU meter screen saver on the Classic to the stock one on the Touch. The 3rd party ones are nice though.

    I was going to say Pass X350 and the XA series I think all have them. However they don't move a lot but they have meters.

    They are an indication of bias current pulled through the output stage and not power output so won't vary much unless by chance there is a problem.More cosmetic than really functional IMO.

    Not really cosmetic, we got Ricardo's to move a bit on his X250 with his Maggies hooked up. It indicates bias current, but the main thing it indicates is when the output stage is moving out of class A and into push/pull A/B. Also when it's pegged you are essentially approaching the limit of the amp. IMO, much more informative than a "power" meter which is not very accurate, but cool to look at.

    Kinda my point Brock,for the most part the needle will deflect very little.Maybe fun to look at the first few times but thereafter essentially becoming a fancy on/off indicator.Ofcourse all stated as IMO YMMV.

    I'm sure they are some nice sounding amps...at $85,000 per pair. I'm skeptical about their testing methodology though :wink::smile:...

    "We began the work with a group of listeners and upgraded the uniformity of their playback systems with components chosen for the ability to reveal differences between amplifiers. We did not do AB or ABX testing - people lived with prototypes as long as they liked in their own system, and the only changes made were to the amplifiers themselves.

    We built sets of modular prototypes which allowed us to alter any given part of the amplifier - the heaviest parts, the heat sinks and transformers and such, stayed relatively static so that one person could easily make the changes.

    At the same time we began an examination of the characteristics and sound of some other types of gain devices (tubes and SITs) and also alternative versions of the Jfets and Mosfets which comprise our current products.

    The process took about three years. In the first year we had settled on most of the power supply design and the physical chassis and heat sinks, and in the second year we finalized the basic power output stage and front end. In this last year we have been tweaking the front end circuits and the biasing arrangements and values of the output stage."

    This is weird -

    Just went to their website - 20W per ch ??

    http://www.luxman.co.jp/global/product/ia_l-550a2.html

    I bet they are the cleanest watts, beginning with the first 1/2 watt

    what's weird about that? 20 wpc is 7.7 dB more RMS juice than my amplifier is rated for at reasonable levels of distortion. I honestly don't know what I'd do with 20 wpc.

    No meters, though, on mine...

    And to think this total hack, Nelson Pass, has been extremely successful even though there is no ABX testing of anyof his products. It's all done ear by several trained and experienced listeners. It's also amazing that he has more patents in the arena of stereo amplification than just about anyone else and is considered one of the best if not the best designer of SS amplification around. This methodology has encompassed his entire career and he is considered my many to be the preminent SS amp designer of all time. His products sounds damn fine as well.

    How can that be? I think the world is going to end now.:wink::cool:

    So I guess most are looking for dancing meters that signify nothing? :lol:

    The fancy off/on meter tells of current draw and when you have left Class A, to me that's important, but to other's maybe not so much. :wink:

    VU and flourescent power meters are woefully inaccurate and extremely slow compared to the speed of the signal, to me they are useless other than pretty to look at. I like me some Magic Eye tube's, however :lol::cheesygrin:
