Now, everyone, I too have my challenges: HOW can I make an acceptable phono preamp, (plug in card) that will retail at $500? Can I do it? I'm sure that many here think that it is easy, but I have to go out of my way to find cost-effective EQ caps, resistors, and IC's that work well enough so that I am not embarrassed by my effort.
Any suggestions about caps, anybody? Please be serious, as I critique any suggestions. (you were warned, no more mister nice guy) '-)

Some have tried, the attempts have failed. The common ground of the shows is flawed.

Is this the common ground you speak of?

Yes, PMA, until you open up to new ideas, we will have a problem. Of course, you are an excellent design engineer, but fas42 is in the right as well. We don't want "funniness" but we have to do what is necessary to make audio equipment sound its best. That is a fundamental key to excellent design, rather than just good engineering.

Truly transparent electronics is what we design (and adjust) for. Everybody knows that, but just making it work in engineering terms does not get you there, for the most part.

I'm talking about the trade shows, everyone goes, there are always excuses for this or that component not showing its best and nothing is resolved.

BTW when I took my TT out of storage and the cart was bent the headshell also was permanently damaged so I went to one of Cambridge's oldest repair shops for a new one. They had a big yawn over the idea of "vinyl revival" no evidence here.

There's is no excuse for having poor sound at a trade or audio show , bad product..?

Room? Come on, there numerous equivocations about room acoustics in trade show threads. Also this is not about poor sound vs the only good sound. No one said it was poor just not good enough to declare a winner.

I was reading some of Paul McG's stuff on his PS Audio blog, it came across as eight legs bad three legs good no IC's in here dogma to me. This is how the posses are formed.

The ac voltage in most of Vegas is bad all over the place and noise this you can design for but like Scott said the rooms and noise from other rooms is a problem. As for Paul McG look in the power plant they have lots of 8 legger in them tucked away. I am using a p300 as we speak. the oscillator board is soft ware driven in the latest models guess CPUs are ok 8 legs bad .
