Pass X-250 and Tube Preamp

I'm very happy with Pass X-250 and ARC LS15 for the past year.

You can increase your odds of success* by keeping the interconnect cable short; 2m or less would be good. The lower the output impedance -- closer to 100 ohm than 500 ohm -- the better your chances are.

* avoiding loss of dynamics, truncation of frequency extremes, and loss of immediacy.

Best of luck,

I've never liked my speakers (thiel 2.3) with tubes. I currently loving and enjoying my pass labs x-350 and x-2 the synergy and musicality is awesome.

Try to find a tube preamp with balanced outs.

An inexpensive good tube preamp (true balanced, use XLR)that worked wonders for me was the Cary SLP-2002. Use 6CG7 gain tubes instead of the 6922's to reduce the gain to match the high gain output of the X250. I used to run this combo & liked it better than a Pass X2 pre w/the X250. There are many past threads on this subject you can reference too.
