As noted above, well tested, low microphonic tubes are required in a phono amp. better tubes can help, e.g. Siemens of Telefunken, but an 834p will never sound detailed or clear, at least, not without extensive modifications (with which I have no experience.) Lush and smooth, yes (in my system, too much so, just as you suspect.) But you have ss amplification, maybe it balances out. An 834P is a good place to start, but looking at the rest of your system, it is not up on the same level.
Which 12AX7 tubes for EAR 834P phono stage?
I am experimenting with vinyls, and acquired EAR phono stage for a starter. I've compared the sound of EAR against Camelot Lancelot, and Sutherland PhD on two different systems. To my ears EAR sounds lush and smooth, perhaps a little too much so. I would like more lively and dynamic sound, like Sutherland phono stage. Can I replace the tubes in EAR and make the sound to the direction of more lively and dynamic? Or do I need to look for a different phono stage? I'm currently using a Rega table with Benz Micro MC cartridge loaned from my friend. I will be using a B&O table with moving iron MMC 20CL cartridge when I have everything set up next week or so.
