Maybe as a generality, but there certainly are tube amps that are voltage sources, and solid state amps that are current sources. Most tube amps, even the ones that have quite high output impedance still fall on the voltage source side of the dividing line. Remove the feedback loop on a pentode amp and it does become a current source.

What hasn't been said yet, is that (until recently) the triode is the most linear voltage amplification device made by man.

In my double blind listening tests, people actually preferred MP3's over the original uncompressed files. I say, stick with mp3s.

Those "spirit" generic capacitors are prime candidates for modding.

Try Glen Moray 16yr
Very smooth, not much peat, yum. My current favorite.

I suppose that some music these days is so highly compressed and has such a limited dynamic range it may not matter. But anything well recorded? Really?

Yes. Very good. I don't consume much alcohol, so don't buy much (usually cider for the wife). A bottle of scotch would last years, my limit is close to as little as you can put in a shot glass and still cover the bottom. I get my samples from visits to friends.

Nothing wrong with Crown, makes a dandy cocktail too.

You are absolutely correct. In fact my ultralinear probably acted more like a voltage amp than a current amp, since I used about 30 dB loop gain (a lot for a tube amp!) and tweaked the phase with feedforward compensation until it was stable. Nevertheless, it was distinctly more "tubey" than solid state amps and distinctly less "tubey" than any tube amp I ever heard until the mid 90s. It was quite unique for its time (not a reinvention of the wheel by any means but at the time nobody cared about tubes at all except for nerdy me ) and would certainly be considered a fancy boutique amplifier by todays standards.

It had full frequency response (power bandwith of 20 kHz @ 20 watts RMS very good for a tube amp of 37 watts RMS) , it was very dynamic, it made every single speaker that I hooked up to it sound better, it had 4/8/16 ohm outputs, it had 3 dB of voltage headroom, it had very soft clipping with no nasty artefacts at all, it was all that and a bag of chips.

Again this is true, but the benefits of an ultralinear pentode push pull amp can't be denied. With thoughtfully applied feedback, it becomes virtually a moot point.
