All Ci does is to reduce DC gain at unity, it doesn't make or break the feedback loop. This discussion should now move to the DIY forum, don't you think ?

point taken - but thanks - I am greener than emerald when it comes to DIY - but somehow, my solder joints are very good

Have you guys heard of these. I think they may have been slowed down by the economy but the one in Menlo Pk. is going great.
TechShop is the SF Bay Area's Only Open-Access Public Workshop -- Welcome

For someone who has heard nearly all SS amps you can back your opinion of it being better than any other SS. I am talking about someone who hasn;t heard many other amps and still claims it's the end be it all of amps..

I should have explained that clearer I guess.

Leaving the B22 out for JUST a minute, that is specifically why I take my builds to meets - to see how they measure up to 'commercial' offerings. I think once Pete Millett heard my BH, he actually was intrigued for a few seconds about electrostatic - which he never has been before.

The previous generation MH had better parts and performance (per other observers) than the Headroom because I used Black Gates, tant resistors and stepped attenuators (as opposed to RK27), along with all silver wire. The parts were better, and, overall, it showed. The case was NOT as pretty because that means less to me than others.

In fact, I wrote reviews about a m³ and the Millett Hybrid, but, you know what? No one cared, because few people had ever heard them, as opposed to, at the time, ASL, the Singlepower toasters, and CI / Sudgen Headmaster / DAC1, et al. While the sound matched up, the obscurity was such that 'discussion' (other than meet threads) was virtually nonexistant.

The vast majority was met with benign neglect, and, in fact, the DIY forum was on the verge of collapse due to the then 'mod' trying to insist DIY had to include making your own ion implanter to make your own chips. It was, to say the very least, a totally hostile environment, that, I STILL suspect, was meant to help sponsor sales.

That most people cannot DIY makes them uninterested in the designs many of us enjoy. Better? Who cares, but we have the options to take equal (or better) designs and make them far better depending on what we want to spend.

I simply prefer to spend my $$$ on the circuit, not the casing.

Great post. I think you have made valid points, and I respect your choice to prefer DIY.

Agreed.

Yup, she's a plain jane in a boring case with precious little in the way of frills or fancy stuff on the outside but I don't think that anyone that heard it at CanJam came away wondering why I'd bothered to build it.
