Jolida FX Tube DAC

With the Jolida Glass FX Tube DAC can you roll in other 12AX7 tube types such as 5751, 7025, 6681 or 7058 tubes? If you have rolled in these kinds of tubes what were your thoughts on them with the FX Tube DAC?

I totally lost track of this thread.

Thanks for sharing Sfar. I've definitely made not of what you have tried in the FX DAC. So far I have a lot of NOS tubes from the mid 60s and 70s to try. The only new tubes I have are the Tung Sols, Mullard reissues, and various Groove Tubes that I got from music shops. I finally did get a Jolida Glass FX Tube DAC and will definitely try the 5751 tubes in place of 12AX7 tubes. The reason being is that I used the Glass FX Tube DAC with NOS RCA Grey plate 12AX7 tubes and holy cow I only had to move the volume control on my headphone amp up by a hair before the music got too loud. I'm hoping the 5751 type tubes will help.

Plosive. Thanks for sharing your exp as well. I'm going to be doing something similar to our set-up. I have the Oppo BDP-83SE and will use it as a transport to the Jolida Glass FX Tube DAC. I'd love to hear the BDP-95 W4S DAC-1 combo you have. I like the BDP-83SE's sound in my system and am hoping the Jolida will add a different flavor to the music. I too have a Jolida 502 amp. This should be fun.
