What is the warmest receiver...

Is the receiver going to see duty as a multi-channel processor/amp for movies or will it be used in a two channel system only?

If you're looking for a music only amp and can do without a tuner consider the 100wpc Jolida 1501 RC which uses a tube preamp section and solid state amplification. They go for around $750 new.

Good luck!

Give a listen to NAD. You might like what they offer.

You might look into Marantz receivers. The 300 series, to many problems with the 400 series. They are very musical/warm.

I own a B&K but I love that Marantz sound. I used to own the SR-14 but wanted bass management, Still....the Marantz is easily the warmest of the bunch you mentioned and honey sweet.
