Khaki - Any problems with the power tubes of your Diavolo? I'm considering an Art Audio amp but have heard that the power tubes tend to be very microphonic and "sing along" with the music. How does your Diavolo compare to other SETs such as Cary designs (warm, a bit soft)? Is your amp on the warm side or cool side? How has the company been to deal with, if you've had any dealing with them? Thanks in advance.
Art Audio Jota - Tube Modifications
I have the Art Audio Jota 52BX running 32 BX tubes in it. Speakers are the Avantgarde Duo's with the Sony SCD1 and TACT 2.0 RCS on the front end of the system.
I have been experimenting with various tube configurations and wanted to share what I found withother Jota owners.
In March of this year, I purchased a matched pair of Telefunken 6DJ8's and a matched pair of RCA 12BH7 1960's Classic Reds Low Mic Superline's tubes from Vintage Tube Services. The finishing touch was putting Top Hats Tube Dampers on the Telefunkens.
After a solid 40 hours of burnin, I did my critical listening. WOW! I finally found the sonic qualities I had been looking for.
Today, the tubes have well over 500 hours on them and just keep getting better.
The sound is a DRAMATIC improvement over the standard tubes that are shipped with the units.
I had tried several eserteric Russian tubes, several different Sieman's, RCA's, etc. Nothing came close to the detail, air, soundstage and tight bass that this new conbination of tubes produce.
