Is there any such thing as a high end receiver?


I am putting together a system for a friend who knows nothing about electronics, has no technical skill, but is a professional acoustic musician and likes sound that is smooth and sweet above all else. I intend to find her some LS3/5a's and maybe a tube cd player and I don't want to burden her with amps, preamps, tuners, interconnects and the whole rigamerole. Therefore, my question: Anyone know of a receiver (under, say, $750 used) that sounds sweet a la e.g. a Grado cartridge or LS3/5a's? Do all receivers sound like Sony's?

Two companies that used to produce really decent sounding receivers were NAD and Rotel. The NAD receiver were entire entry level separates placed in a single box. The problem with most receivers is that each of the separate sections share a common power supply. That often limits dynamics and clarity compared to separate components that have their own power supply. Another issue that most receiver tuner sections are an afterthought and are not very good. If your friend is going to listen to quite a bit of FM my suggestion would be to go with an integrated amplifier and a separate tuner. As others have mentioned, the Creek is a great sounding integrated in your price range. They also make a very good tuner.
There's a mint demo Magnum Dynalab MD208 up for auction right now at about $1500. Phil's suggestion regarding classic Luxman is also certainly worthwhile.
Yeah, I'll throw in with the people that have mentioned the Magnum Dynalab MD208. Magnum Dynalab is known for their tuners and the preamp/amp section of the MD208 is based on Simaudio integrated amps. Expensive, but well designed and nice to look at. But for $750 used , I really can't think of any receivers close to the Magnum Dynalab. Maybe a good integrated.
