Aesthetix Calypso vs. ?

I have this on loan from my dealer, and am wondering what other preamps I should try within this price range.

I think the Calypso betters my BAT 3iX, without the 3iX's somewhat closed in on top and darkish midrange.

The 3iX does seem to win in the midbass, and I still very much like the its overal soundstage presentation. I'm wondering if I should try some tuberolling with the 3iX before I give up on it. I just have the standard Electro-Harmonix 6922s in it right now.

(I tried some Tung Sol 12AX7s I had in the closet in the Calypso. Lovelier midrange and deeper soundstage than the Sovteks, but too much hiss).

No. Mullard CV4004's work well. I have tried some GE 5751's which are lower gain and quieter but prefered the CV4004's.

Not sure why your dealers unit does not have the gain jumpers. If you buy a new one it should have them and it lowers the gain by 12db's.

If you use low noise NOS tubes the Calypso sounds better in the high gain position IMO. Unless you use really efficient speakers like 100db plus.

I think it's just a very old unit. If I go with the Calypso, I'll probably get new unit.

The new Calypso will come with the lower gain and sounds great with the Vandy quatros in a balanced system
Later look at the matching Aesthetix Atlas amp
or a pair of Balanced Quicksilver V4s

"Primaluna Dialogue 3 would "smoke" the BAT ... (he doesn't think the dark character can be changed much.)

My BAT preamp is very, very dark. But this can be changed. They make a version in silver as well.

Personally, I would be concerned about the Primaluna or any preamp if it smokes. That probably indicates a need for service.

Groan.

Seriously, which BAT do you have? I have to say that I still prefer the 3iX's big soundstage presentation. I may just stand pat.
