Basically you are saying the Cambridge DAC/Pre-amp will significantly drag down even a $10K level amp...I wonder if others agree with this?Uh, that’d be yes x 1000!!! NEVER underestimate the importance of a preamp — it can make or break a system. The DAC is up there two so you’d be doing a nice amp a disservice on both counts.
This conversation needs to start with what sound characteristics are most important to you and what you’re looking to improve upon over what you are hearing now. Otherwise — and as you can already see happening here now — you’re just going to get a wide range of personal preferences that may or may not have anything to do your own, which is basically useless or even counterproductive. So start by stating your personal preferences and goals and you’ll get much better recommendations here. My $0.02.
