Aesthetix Calypso owners - need your help

I just bought a Calypso used. Pretty excited about it, but I need some guidance:
1. anyone knows the difference between low and high gain aside from low high volume? I got it with the setting at low, and tube noise is pretty low but sounds reserved so far. Changed it to high setting the next day, and now its sounding much more alive. But alas, I can hear tube rush from my seat. is this a common problem?

2. Anyone knows if the HT by pass bypasses the tubes? I am combining with my processor for movies but don't want to waste tube hours

3. I've been reading alot of threads about calypso, and tube roll was mentioned alot. I'm pretty much out of budget but willing to invest 100-200 bucks on NOS tubes if it brings alot of improvement. anything good at this price? the ones that I got are Sovtek for 6922 and Teslov for 12AX7. I also got another set of tubes which I haven't tried yet

lastly, anyone know Aesthetix service phone number?

look forward to your comments.. thanks!

Try 805-529-9901
I'd buy the 12AX7's first Mullard CV-4004 as the output has more affect on the sound, under $200
That being said the Sovtets are thin sounding (bad) and with the Mullards the sound might be depressing! Between the two these are the worst.
You need to replace both pairs!!
When you do H/T put the Russian tubes back in!

Those are the tubes but you are looking at the"Bought the Gear here" price, if you didn't they're $100 each, gold might be good for preamp output circuit.
I think the "prime" year is '81, but '85 beats nothing!!! The best 6922 I found "in my system" with the CV-4004 was the Amperex Holland 7308 very detailed with a fuller mid than the US 7308.
