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!

Thanks alot for the info. I've been doing some reading on tube roles for this pre-amp. The only info that is consistent is that 10M gold pin is the way to go - but the price!!! also, I have no idea where to find them.

Anyway, Any other info you have I would greatly appreciate it.

Mhz - the volume control is generally between mid 30s to high 40 depending on source CD. not a slam dunk info to decide what setting to use, but I will keep on listening both ways for some time before deciding. Quick question for you: do you know Jim McShane contact #? thanks! Dion

The best tubes for your Calypso will depend on your system and your ears. So its a very personal choice. The experienced tube dealers mentioned will work with you to achieve the sound you prefer from the Calypso.

I have several pairs of tubes for the Calypso which I selected to allow me to tune the system given my mood on any given day. Some sets provide a bright, sunny day presentation others more of a vibrant cappaccino. Perhaps you want to add some dark chocolate? This ability to tailor the sound is just one of the major pluses of a responsive tube preamp like the Calypso. I suspect you will really enjoy owning this fabulous preamp and hope I've helped.
