Transport & tweaks for audio logic 24MXL

Rcprince's advice is spot on. As a long time AL owner, listen to his thoughts carefully. I am among the crowd of AL owners who have an earlier model, in my case the M34DSB. I use a CEC TL2 and the combination works very well. If you search the threads you will find many who are using the CEC/AL combination. The only thing I would add (which has been in prior threads) is that this DAC responds VERY well to good air isolation. I use a Townshend Seismic Sink and I believe that Rcprince is still using a K-works. IMO, air isolation under this DAC improves any tube that you will use.

Glai:
Rcprince's experience with tubes from his use in the previous response are all good recommendations and are all in the upper crust of the 6922 tube family. There are a wide selection of tubes in this family, spanning from "modest and affordable" to really expensive. You might find it helpful to try a small selection of "affordable" choices to get a taste of the changes you will find in your system. In addition to Siemens and Telefunken, you might want to look closely at the Ameperex family: there are a lot of choices. I have had very good success with carefully selected Brimar ECC88's.
