@bthartman your experience supports what I recommended earlier in this post which is to connect DAC to amp and use DAC’s preamp section.
The McIntosh preamps and integrated amps tend to homogenize the input signal from different sources. It could be a good thing if that’s what you’re after. But if you’re looking to easily discern differences between components and cables, this won’t work. This isn’t a knock on McIntosh…there are other brands that stick to the same design philosophy.
upgrade question regarding DAC and streamer
I want to improve my system's imaging after having carefully placed my speakers and done some room treatment to reduce reflections.
My system includes a McIntosh MA8950 integrated amplifier, Sonus faber Olympica Nova III speakers, a Silent Angel Bonn 8 network switch and its LPU, and an Innuos Zen Mini Mark III with its LPU. I use the Mini with its Sense app to stream Qobuz to the McIntosh's DA2 DAC.
I am considering a DAC+streamer such as the MSB Discrete (with render/streamer add-on, and its separate single LPU) and the dCS Lina (with built-in power supply). My budget is about 15K.
In the future, I will get a separate preamp and amp, perhaps using the MA8950 as the preamp for a while.
The dealer with whom I have a great relationship carries MSB, dCS, and Innuos (their Stream3 may also be a good option when it comes out). Of course, I will listen to the DAC+streamer options with the same/similar integrated amp and speakers at the dealer's.
For the purpose of improving imaging with my system/room/good speaker placement, does upgrading the DAC and streamer make sense, or should I upgrade to separates first? Or something else?
