I think you could easily try running the squeezebox to the NAD assuming this model NADs pre and amp sections can be decoupled in the rear like many NADS can to use the pre-amp inputs to the power amp section only and see how it sounds in comparison as an easy test.
Squeezebox 3 As A Preamp?
I am having the constant upgrade itch, however, I am on a budget and I am sticking with my Squeezebox 3 as a source. My question is, how can I upgrade my Squeezebox 3 sound the cheapest way possible? I have an old NAD 3155 integrated that I am impressed with, but it does not have a remote and it is not quite what I am looking for as far as sound goes. I was thinking about keeping the 3155 and using its strong 55 WPC amplifier section and buying a great, used preamp. I was also thinking about buying a great used amp and using the Squeezebox 3 as the preamp. Keep in mind that I do not want to buy a DAC at this time, that will come next. Power is not important to me, just the most lifelike sound possible with a budget in mind. I cannot have too much power, I live in a condo with grouchy neighbors.
