Not just you. The total package is something that for me ALL HeadRoom amps have over the competition. But you know I think that. I wouldn't consider another commercial amp maker at this point, due to the combination of sound quality, features, design, and rock-solid build and support that the HeadRoom amps offer. And indeed if I could go back to the time before I found Head-Fi, I could absolutely still live with my Supreme from 2004, which I bought used and WAS a steal for the price, as my only amplifier. It's the overall package which keeps them from flooding into EBAY.
But $400 for a Cosmic with a module from before 1997 to me seems ridiculous, and yet that is what people sell them for. I just can't possibly say in good conscience that that amp will sound as good as the other current options (including HeadRoom's own) at that price point - it won't. I admit I have not heard the original HeadRoom modules before 1997, however I have heard their future incarnations which were simply parts upgrades without any significant redesign, and I have a pretty good handle on how they compare with current offerings. And to me it's a shame that people end up paying this money simply because they don't understand what's inside. And I never read any ad copy. I just sat there with an amp and a pile of modules and listened.
