Aesthetix Calypso vs ARC LS25 MK2

Husk: Keep in mind I don't own the Calypso but rather the Callisto Sig and Io. Check my thread from a few months ago on the tubes I tried with the Callisto here.

It's anybody's guess if what worked so well with the Jupiter models will do the same for the Saturn.

My dealer was nice enough to let me hang onto the tubes till next Monday, so I will try to do a comprehensive tube roll this weekend. I know the Supra LoRad pc worked wonders on my cdp, and again, I have two more to play around with. I'm going to leave the one on the cdp and try a couple of different combo's. Pre & cdp, monoblocks & cdp, and will report my findings for anyone interested.

ARGHHH, I hate swapping stuff in and out, it's too much like work.
But when you have access to stuff for free, you gotta try it, right?

Perfectionist, Can you tell me exactly which tubes you are using and where you got them? Is there any tube noise with the new tubes? Thanks, Husk

Husk01, the tubes are listed above, but here they are again.
Tungsram, Brimar, GE longplate, all 12ax7's from Upscale Audio. They are all very quiet except one of the GE's pops every once in awhile, but it's really not that bad.

Well, do to some personal issues in my life I didn't get to spend as much time A-B'ing as I would have liked. And then there's the powering up/down, warming back up, etc. What a pain in the ass. Is it a fair comparison to pull tubes that have been on for a few hours and pop in cold tubes for a listen? Do the tubes need to be on for 20, 30, 60 minutes before they "settle?" Or are they good to go right away as long as the pre is still warm? I'll say it again, what a pain in the ass. But, I did make some headway. I finally settled on the Tungsram 12ax7's, with the GE Longplates (ca.1963) a close second. I quickly ruled out the Brimar's which are smooth and laid back, but I listen mostly to rock and they are a little shy in the bass area IMO. I felt the GE's were decent in the bass, but the soundstage wasn't as wide and open as with the Tung's. Also, one of the GE's would "pop" on occasion, but were overall quiet. But tube noise is no longer an issue with this unit, nice and quiet thank you. I am also ordering two Supra Lorad pc's, one for cdp and one for pre. These are excellent pc's for the money IMO. Very detailed and open sounding. I was only able to briefly put Lorad's on my monoblocks, hence, I really couldn't "make the call."

Thanks to all for the "sound advice" over the last few weeks.
