Post Subject: Input tube and DC heatersPosted by Paul S on: 11/25/2008

I don't suppose the input tube was a 437A?

And perhaps (at that price) silver trannies? I have never never knowingly heard silver trannies (apart from my Ortofon step-up), and I wonder why anyone would pay that much for them when amorphous models work so well while costing far less. In other words, I wonder about the cost/benefit of silver trannies in DHT amps.

I am followiing along because I am always interested in how designers handle the variables, which variables turn out to be audibly significant, and which significant changes prove to be for the better, in which contexts.

The Cogent crew had good-sounding 300Bs; I'm thinking Wavelengths; but they did sound like good 300Bs; very clear and very nice on their musical choices, but certainly less crisp and incisive than good 2A3s or 45s (AC candidates...). The Cogents did not play anything "tough" while I was there, and, as reported, their speakers had obvious problems that made serious conclusions about the amps impossible.

Best regards,
Paul S
