The RB-1090 has been out of production for 10 years. Replacement is the RB-1590. Here is Stereophile's review of the RB-1090 from 22 years ago. https://www.stereophile.com/solidpoweramps/100rotel/index.htmlHere are some measurements:
They are now part of Sumiko.
I know they are old. However, most of Rotels class AB power amp series had the same construction with only minor mods over the years. I doubt there are significant measured differences between the amps of the same model serie. Measured performance was usually excellent. If they went class D, that is another story.The RB-1090 has been out of production for 10 years. Replacement is the RB-1590.

LOL - You really are a master of strawman B.S. In fact, I think you qualify for my "Giant Strawman " award.But then again, someone will chime in and say all amplifiers are the same and no one can hear any difference.
Rotel is swimming in the same pool as Denon, NAD, and Cambridge, and compares favorably in that group. You could argue that this niche has been replaced by the new wave of budget gear from Topping et al, but time will tell how those stand up. Rotel has been around since the 1950s, so has nothing to prove in that respect.Rotel is a brand that was pretty much dead in the 80’s. I can’t figure why it was resurrected it serves no real purpose today. In my opinion.
That actually looks more like a strawwoman.LOL - You really are a master of strawman B.S. In fact, I think you qualify for my "Giant Strawman " award.
It appears that you are oblivious to the concept of "qualifying" parameters and "conditional statements" People who are even minimally familiar with psychoacoustics and audio electronics design might state that "well designed and engineered amplifiers that are used within their limits and operating parameters, and in carefully level matched blind testing will almost certainly sound the same".
If you compared those amplifiers in sighted listening sessions - and without level matching and instantaneous switching, you are very likely fooling yourself (or your brain is fooling you).
