I have to say my 2 favorite receivers I own are, the 2285b, & the 2330b. I also owned a 2238, passed along to my son. Of the extensive sampling of my Marantz collection, that's my choices. My 170dc's(2ea) & 3250 preamp, or 250 amp, & Model 33 preamp is also right up there, & look as great as they sound. But the question was regarding receivers. I do have to mention the speakers I use & love are 4 Pioneer HPM-100's & 2 Klipsch Forte's. When I bought my 2285b in the 1977 I sampled almost every speaker on the market then, and bought the HPM-100's. After 38 years they still sing & added a second pair a few months ago, the second cost almost 2X, what I paid for the first pair. The Forte's also sing, from Classical, Swing, Bop, Jazz, Blues & all forms of Rock. My tube stuff performs exceptionally well with these speakers too!
As for the rest of my collection, my son will have to pry them from my Cold Dead hands!!!
