Best Tubes for Raysonic 168?


Can you 168 owners give me an idea of what tubes you have used? I replaced the stock EH 6922 with Jan Philips. I like the Philips much better than the EH 6922's. Better mids and highs. Anyone try cryoed 6h23n-EB's?
Thanks!

In my system and room the Jan's were to bright and thin,I put the origonal EH's back in! I bought a quad of Amperex White Label PQ US and put a pair in the bal I/C section with the EH's in the outside S/E spots. This sounded fantastic, I am now using all PQ's, there is a reason people pay for Amperex. Before you spend a lot maybe try a pair of Amperex 6DJ8 Orange lable to hear Amperex sound in your system and room.
The best 6922s I've used in my Shanling have been Amperex Bugle boys and Amperex (holland made) Orange label.
I have been using the Amperex 6922 white label tubes with fantastic results. Warm, detailed, very musical tubes. Definitely upgrade the EH 6922 Russian tubes! You wouldn't be disappointed with the white labels.
