What are the true benifits of a Pre/Pro vs. using a receiver with Pre-outs?
Would you really notice a difference?
I think there are two reasons. While at Bat's GTG I mentioned that I really liked my Monitor Audio speakers but they seemed to sound a bit harsh at extreme listening levels (where I rarely if ever listen), and someone suggested buying a bigger power amp and using the front end of my receiver. That would be cheaper than buying a whole 'nuther receiver with more power.
The second reason: There's little in the way of advancements in power amp technology, but front-end tech seems to be changing yearly (HDMI 1.2, then 1.3, then 1.4, then 3D, then Dolby Digital TMX Pro EIEIO with Ninja™, etc; its cheaper to just buy a new front end and keep using your decent power amp, which can be perfectly sufficient for the next 20 or 30 years.
If I had it to do all over I think I would've gone with the Marantz prepro/power amp.
EDIT: I'm sorry Neil, I didn't read your question very well, your situation would require a separate power amp in both cases.
I guess starting from scratch it'd make no sense to buy a receiver knowing you'll be using the pre-outs, why pay for the amp section if you're not going to use it? But, in my case, where the receiver purchase has already been made, I'd see no problem using the pre-outs. Sure, a dedicated pre-pro might be designed better or have better features but that's an argument that could go either way depending on the specific equipment, and the "golden ears" in the room.
