the classic tube sound & the modern tube sound


as a hobbyist since 1965, i have noticed the disappearnace of the classic tube sound, and the emrgence of the modern tube sound. the classic tube sound is exemplified by early conrad johnson amps and preamps, such as the pv 1 and premier 3 and the mv 45, mv 75 and mv 125, audio research sp 3, sp 6, cary audio slp 70 and mac gear of the 60's.

most preamps in production today, manufactured by cary audio, audio research, conrad johnson, art audio, etc., are attempts by designers to produce preamps and amps which are "neutral".

are we better off with the modern tube sound, or do you miss the vintage tube sound ?

which do you prefer and why ?

My dad owned and operated an electronics repair shop in Brooklyn and was a very strong proponent of tube equipment, mostly because of the ease to repair it ... replace a tube versus attempting to repair a printed board. I have been around tube gear all my life. My first tube systems were strictly hobbyist set-ups. Two that I remember were:

1. a Philco (before being acquired by Ford) tube amplifier and a Voice of Music turntable (crystal cartridge)
2. a Grundig tube amplifier with a Garrard turntable (crystal cartridge)

Speakers were homemade infinite baffle designs with Alnico speakers that my dad had available.

When I started working, I purchased solid state equipment and did not return to tubes until 4 years ago, when I purchased two Prima Luna tube amplifiers.

With all that said, what I liked best about the 50's/60's tube sound was the richness and immediacy of vocals. The sound always had presence. I don't remember being too concerned about accuracy per se, because there was a smoothness to the sound ... music just sounded good, regardless of the type of music. I had no problems using tone controls to even out the sound, that was what they were there for.

Then, I became an educated listener. I trusted wholeheartedly what EPI speakers was saying about not using tone controls and listening for linear sound. Thing is though, I was not always thrilled with the sound coming from my systems. Part of this was changing over from vinyl to CDs, though I was happy to be rid of pops & clicks. The big thing though, I was not getting the richness and warmth from solid state that I had gotten from tubes.

A few years back, I purchased two Prima Luna products ... the PL2 integrated and the PL5 power amp. I got back the richness of sound and almost holographic imaging that I had 35 years previously. What was different was the accuracy of the new tube amps ...they were almost as accurate as any good solid state amp that I had owned. The sound was not only immediate, but instruments were more distinct. Granted, I have comparatively way better speakers and source components than back in the day. But I don't remember the music coming from any amp in my dad's shop, sounding this clear and clean or the background sounding so quiet.

As an aside, I would accept on the face of it, when reviewers would say that a solid state amp sounded tube like. Not really. Even the most tube like sounding solid state amp does not sound like a tube amp.

To answer Mr. Tennis' question ... I prefer the tube sound of today. It is an improvement of what I remember from the older tube amps.

Best regards,
