As you most know I deal in dozens of them, and have played with several of most everything they made. I'm certainly no expert, just reporting on what sounds good, and works good for me.
I get real good, and clear, FM reception here, and these 2300s all have very good tuners, so they are very listenable. Most sound almost as good as LPs/CDs (when properly aligned)
The 2300 models (2325, 2330, 2330B, 2385) are all in another class above the 2200 models. Although the best in that class are the 2270, 2275, 2285, and 2285B.
The 2500 and 2600 are a step near to the limit in receivers.
In the 2300s I like the 2330. It's alot like the 2325. The 2330 seems alittle more refined if you know what I mean. Most of the 2325s I see need work. Not sure why, but very few come across the shop table, that don't need several things fixed.
The 2330B is a different model really, not anything like the 2325 in the way it's constructed.
The 2385 don't seem to be a ton different than the 2325-2330-2330B. Just more powerful of course.
As usual, it comes down to $$$ How much do you want to spend??
