Cary Audio CAD 211 FE tubes upgrade.

I'm running that combo, too, in one setup.  I have an SLP05, which is a much better match with the CAD211fe, but it's in another system.

Anyway.  I'd suggest next targeting a replacement for the stock 6sl7.  Then, assuming you have new production EHX or Tung Sol 6sn7 in the SLP98, changing at least the front two 6sn7.

Those two spots will likely give you the biggest opportunity for change/improvement.


If you get the 845 Tii, please post back on what you think.

What about Shuguang tubes?

Replaced 845 stock tubs to 845 Tii. Stock tube give a lot bass, boom not tight, less vocal, with Psvane 845 Tii, I can tell the different right away, more vocal, less bass, that what is want to hear.
I don't know replace 300 B will make the sound better or not. Any one replaced the 300B to 300 Tii, please post feed back.

When I used the 845 tii, they opened up a bit after about 30-40 hours.  Not a huge difference, but bass improved, and a tiny bit of an edge on the upper mids seemed to smooth out.

I'd suggest getting used to the sound difference the 845 tii made and then swapping the 6SL7, assuming you have new production TS in there, now.

Really, I'd suggest targeting the 6SN7 in your SLP98.  I find the bigger changes/improvements are generally had working from the front rather than from the back.  You didn't say what you have in there, now, but, if they're stock new production EH, would be a good place to start, particularly on the front two.  Unless you are one of the few folks that like 'em.

But, if you go with the 300B, next, please post your impression!
