@yyzsantabarbara thaka for the info, reply, the Holo Serene is interesting. I agree on the Krell Amp, I’ve been lucky enough to be able to try various amps and it’s been my favorite. Noise and synergy are what have me asking the question. I have found it’s hard to match a pre to the Krell. I had a Krell Illusions ii Pre, no surprise it paired the best out of any pre I have tried, dead quite. Sound wise, didn’t love it the way I should have.
@soix my system sounds really good currently but the gains / synergy between the gear is where I think I could potentially improve. It’s that synergy that has me wonder about a high end integrated vs what I have. My next upgrade is likely a streamer if I stick with separates.
@grislybutter I’m chasing synergy but I shouldn’t at the expense of quality of my set up. I’ve had a Krell Pre with a DAC on my system, the gain match was perfect, was quiet. Sound was very good but not great. I found separate DAC’s improved sound and various Pre’s also sounded better. But, matching this amp with a pre has been more of a challenge than I would have thought. Seems to be really sensitive to the gain / voltage settings in the Pre.
Thanks for all of your responses, appreciate it.
