Have you rolled any tubes in that Music Hall?
I've been emailing Chis Johnson from Parts Connexion regarding some DIY mods for the Music Hall. He has been quick to respond and is being very helpful. I think I might try the Burson opamps as they seem to be the biggest upgrade for the DAC. What's scary is that I'm pretty happy with the way things sound now, but at least the socketed opamps are reversible. If I do pull the trigger, I'll update this thread with some info.

As I understand partsconnexion's description of the two types of mod they replace the existing 6922 tube with a better one ( assuming that the supplied Russian tube is still in the DAC) with a better one in the RCA mods but not in the XLR mods. This suggests that the tube is not used in the XLR path through the DAC, do you think that this is the case? If it is, t'is a pity, as I have now replaced the passive line controller with a preamp that provides XLR inputs so I am now using the XLR outputs from the DAC. If the tube is not used in the XLR path I guess I won't be tube rolling any more; I was looking forward to putting in a Bugle Boy.BTW I can't get my FM tuner to work through my set up, and I suspect that it's an impedance matching problem. Does anyone know of an active thread that could help me with this? I'm at the point of denying that FM signals exist at all.

I'm at the point of denying that FM signals exist at all.You are correct that the tube buffer is only on the RCA outs and not the XLR outs. I don't know why the DAC was engineered this way, but it is. I LOVE the tube sound I get from this DAC, so I am modding only the tube buffer outs. I have no interest in using the XLR outs, but I have read many posts where people are equally satisfied with them. At this point, I am only upgrading the opamps to the Burson's as I'm really very happy with the way things sound right now. I almost wish I had not purchased the Burson's, so I really hope they make things sound "better".Sorry, I can't help you with the FM issue.
Make sure you let me know how the comparison turns out. Make certain you listen for things like stage width and depth, separation, and extension for both the treble and bass.
reviving old thread, which deserves some love.In the market for a DAC which place nice with Song Tower RT <= AVA Omegastar 260EX =< Parasound 2100 preSources/Transport : CD, CCA, squeezebox Touchso, what DAC? anyone tried Denafrips with their salk speakers?Another option I see is get a AVA Dac & later change the pre also AVA??TIA.
