I would like to improve my stereo music quality and having demoed General Skanky's Primare A30.5 I've decided that a power amp is a good way to go about it. I will be upgrading my speakers sometime this year, possibly to B&W 700 series so I'm going to need some more power anyway. I'm considering something like the Parasound A 23 or the Rotel 1075. Obviously I have more options with the Rotel plus I can also use it for the centre speaker, but how will stereo compare with the single amped Parasound or biamped Rotel? I will hopefully get a chance to home demo the Parasound soon but Rotel isn't so easy in these parts. I would have thought it would be the other way around! Any other suggestions on amps to demo are welcome.
