In Reply to: OP Amps, Whats Your Opinion? posted by AudioSoul on June 24, 2015 at 09:48:49:
Indeed you can build an operational amplifier with valves.
There are a lot of potentially very good (op-amp) chips available now and for at least two decades.
Most need real attention to their grounding, heat sinking and Power supply arrangements as do everything else.
Even if you did mostly listen to simple stereo recordings and not to multiple mono-mike pop mix-downs the sound you hear has passed through quite a few op-amps. And if you are a typical audiophile, hundreds of them, over and over.
