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).

Try 3 Herbies Iso cups with lampblack balls under the Calypso. Two in front and one in the rear. You will be amazed. They really focused the soundstage and improved the sound for the better in my system.

Also good NOS tubes are mandatory to get the best out of the Calypso.

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.
