Having just acquired a Marantz 2265, I'm curious: What are the differences for THIS model and it's "B" (2265B) version? I know that in general the "B" can mean almost anything, from a minor fix to major changes. Does anyone know the actual differences for this particular model number?

Do you have them both in possession?

Sort of (technically I own both), but I can't get at the 2265B right now. Eventually, I'll be able to put them side-by-side and compare them, but not all that soon. Just wondering if someone knew the answer in the meantime.

EDIT/CORRECTION: Big, big OOPS!!! I do NOT own a 2265B, but a 2252B. For some reason, my brain got the numbers mixed up. Oh, well, at least now I've learned something, and if I run into a 2265B, I can still get it without fear of duplication!

Updated circuitry. The appearance is changed going from silver with blue dial to silver with silver. classic-audio.com has a Marantz database that shows both.

Thanks. :thmbsp: I should have reserached there (and elsewhere) first, before taking the lazy way out and asking here. "My bad". :nono:

Yeah, the 2265B is the newer model, all silver panel with the same classic blue lights and red stereo light. It probably has a few more or different features and the amp's distortion specs are slightly better. Many think the 22xxB series is Marantz's best looking.

Ah, do I take it then that all the "B" series have that changed-to-silver dial? I can see the difference in the dials clearly by comparing the 2265 with my 2285B; they are on both sides of me right now. Hhhmm, I'll go look at the pics online to make sure this applies to lower numbers in the 22XX series.

I have a 2250B and its the black/blue on silver, unlike the 2252B or 2265B which is all silver. I have those too. I like both styles but do favor the all silver ones a tad more. Soundwise you'd be hard pressed to tell them apart. Although the 65B has a slightly better sounding phono section.

The main differrence between the 2265 and 2265B is that the B has the Dolby Decoder Option.

I'm a little confused.
While this is easy for the 2265/2265B (I'll refer to them as blue faced vs. silver faced, with the silver faced having the tuning wheel below the dial), as least as far as appearance, it doesn't hold true for all of them.

For instance, the 2235 and 2235B look identical. Their specs look identical. They look like they overlapped in manufacturing dates.
Then some "B" units are from different years, are clear successors, some have balance sliders some knobs. It's all very confusing.

Making it worse is the 2238/2238B difference, where the B has the "silver" face, and the 38 has the blue face but with a silver panel over half of the black framed glass part of the face. But they were manufactured at the same time. (It seems all the silver ones from 77-79 have this: 2252/B, 2265/B, 2285/B)

So what gives - is there a "B" line? What's the difference in 2235/2235B? My guess is that there is no rule. Thoughts?

For instance with the updated circuitry the 2265B has 0.05% THD, and the 2265 has 0.3% THD.
Good improvement.

But I will admit, between my 2265B and 2270, I find NO REAL audible differences on the same speakers.
Both sound smooth and clean.
I also have a 2220B running my Advents. It supposedely has 0.5% THD as well, but cannot hear it is it is there and my hearing is excellent.

The 2265 and 2265B was also sold during the same time period. I think it might have been a transitional period to see whether consumers liked the all silver receivers.

There are also variations of the blue and silver faceplates.
