Albert Porter is a true fount of information on tubimg Aesthetix products, so hopefully he will post here. In the meantime, you might check the archives for threads involving Albert and the Aesthetix IO, as I recall some very detailed information about that unit that might carry over to your line stage.
Aesthetix Calypso, Tuberolling questions?
What results have owners of this preamp had with different tubes used. I'm running stock tubes into a pr. of Parasound JC-1 mono blocks now and the sound is very good. Would like to open up the treble a little if possible without messing up other areas. Any info on what people have tried and to what results would be of great help. Thank you

Albert is indeed the resident guru in the Callisto and Io but Jadem6 has probably done more tube rolling and tweaking to the Calypso than anyone else out there. A good place to start is JD's review. |
I am using a Calypso with JC1's also. I've rolled Brimar-England, Tungsrams and GE Longplate 12ax7's, all from Upscale Audio. Still running stock Electro-Harmonix 6922's, have not rolled those. I listen mostly to rock, blues and some jazz fusion and chose the GE's. I auditioned all of these tubes at the same time, and the GE were the best for me and my system. A great rock 'n roll tube, IMO. All of the above tubes were very quiet. The stock Tesla's were decent, but a little closed in & rolled off in both directions, again IMO. |
Perfectionist: Please describe the characteristics of the GE tubes in comparrison to the others when in your system, and explain why you feel that the GE is "a great rock 'n roll tube." I too have the Calypso and primarily listen to Rock & Jazz. When I do get around to rolling tubes, I do not want to lose the detail/resolution & punch that I get from the stock tubes. However, I would be looking for a warmer/richer sound. I really believe that this is system dependant...synergy is key. Thanks! |
