Nothing better than system synergy a Pas Labs Pre with a Pass Labs Amp. If you want an Integrated a Pass Integrated such as the INT-150.
I've owned several Pass amps and preamps myself. I likes the amps very much but not the preamps. If it were me, I would keep your cd player and put all the money towards the best preamp you can. The M6 is a great player. Getting a better preamp will be a much bigger change. If you are willing to buy used, I would look at something by Aesthetix, Ayre and BAT. There are other great brands as well, but this is what I would start with.
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.
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
P.S. I AM A AVM AUDIO DEALER...
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.
