Hello Roger, I've purchased your tubes several decades and liked the quality and longetivity.
Funny how people denigrate my Marantz 7T although I only use it for 78 rpm phono stage. It sounds much like a 7C.
My Dynaco ST70 on my second system has magnificent bass as it was modified from its ultralinear design to a voltage regulated design (taking off the 2nd transformer tap). Added very large storage cap, ss rectification but kept the tube for soft start. Just a wonderful low powered amp.
My friends and I have found some early ss receivers with low power are superior to higher power receivers in the same line. E.g. Yamaha CR 620 is superior to the CR 1020 and higher power receivers. The Sherwood 7100 is superior to the 7200 and 7300. They have fewer stages on the low powered units. I use the Yamaha for video/audio systems although a friend uses them on his Legacy Focuses. Even the Sherwood brings out great low and tight bass on Legacy Signature IIIs (its shocked the seller when I used it to audition them).
I really like your answers on many of this forums questions.
There only place where I strongly disagree is in the use of premium fuses. My amps had standard fuses replaced by SR Blue fuses. The difference in SQ was very substantial. The manufacturer of my big amps went one step further and replaced his fuses with circuit breakers. Now his amps sound nearly identical (we can't tell the difference) from my amps with the SR blue fuses. He is a huge skeptic and this is his only tweak to his system.
I'd like to know what you opinion is of the VAC IQ (continuous autobias) amplifiers. They sounded great wherever I heard them and they appear to be conventional designs well executed. They must have good impedance outputs to make them adaptable to drive many types of speakers.
I heard those Jadis amps on new Magico speakers (maybe the S3 or Q3). I wondered why the highs were rolled off and soft sounding. Probably due the loss of power in the highs. Terrible sounding.
