Preamp for Pass Labs X150.5 or X250.5

Upgrading my Musical Fidelity M6i Integrated and M6 CD/DAC with one of the Pass Labs X.5 amps. Using Usher Be-718 DMD speakers with subwoofer (for now). Was going to look for a used X1 or X2.5 Pass Labs preamp and new DAC but thought maybe another option would be to look for an all in one Preamp/DAC that also has HT Bypass along with ability to connect my sub. After doing some research, a couple that come to mind are used Classe CP-800, or new NAD M51, and Wyred 4 Sound DAC2(not sure if sub will work). Any other suggestions or would it just be better to stick with used Pass Labs Preamps and then an economical DAC? My budget is $3k or below for the preamp/DAC.

I would prefer to go with the Pass Labs amps (per the recommendation of the Usher dealer) but another totally different option would be to go with a better integrated such as the Hegel H300 which has all in one package including HT bypass.

Thanks for the suggestions. I did look at the INT-150 but don't believe it has HT Bypass.

With regards to the other suggestions, do I need check that the impedance of the amp and pre are a good match? A bit confused as to what I need to look for and what potential problems I could run into.

Thanks again.

I've a lot of experience with Pass and unless you are willing to spend a LOT more money than the Pass preamps go with Pass. And in the cases of spending a LOT more money even most of those won't be as good.

FYI: I used my Aesthetix preamp very successfully with my XA30.5 amp. A very good match.

Consider the new AVM AUDIO pre's The new PA5.2 HAS WHAT YOU ARE LOOKING FOR, PLUS YOU CAN ADD STREAMING, DAC AND PHONO OR TUNER. IT IS A LITTLE MORE THAN $3000.00... BUT YOU CAN ADD OPTIONS DOWN THE LINE WITH ITS MODULAR DESIGN
IF SOLID STATE IS WHAT YOU WANT LOOK AT THE NEW PA3.2 MUCH CLOSER IN PRICE TO YOUR BUDGET AND SOUNDS GR4EAT

UPDATE:

Ended up not going with the Pass Labs...maybe somewhere down the road. Decided to stick with Musical Fidelity and simply sold my M6i Integrated and purchased a demo M6 500i while keeping my M6CD/DAC. Wow!!! What a difference over the M6i. Very happy so far. Finding myself listening to my music at much louder levels. The M6i was good but seemed to struggle with my inefficient speakers at higher volumes....not a problem with the M6 500i. It's a beast and even sounds great at lower volumes. Really amazing integrated if you're needing HT bypass and power to drive inefficient speakers.
