Audio Research and Wilson Sabrina

@deep_333 do you mind taking it elsewhere please? 

Believing ChatGpt is like believing an extra lady friend you’re the only one.  They both tell you what you want to hear based on minimal information

I have Sabrina’s. I have run tubes before but I prefer Moon Audio 600i v2 integrated. Personally I think your preamp out ranked your amplifier by a long shot. If you want to stay with tubes get the 150 SE or if you want to sell that equipment, you could buy a really nice integrated with lots more power and control and pocket the money left over which would be thousands potentially

I have had Wilson Sophias for several years with many many different ARC amps and preamps.  I owned the REF 75SE for several years and absolutely loved it.  It was a perfect match for my Sophias and no strain and much higher db that you are needing.  I got a REF 150SE for a short time and heard no appreciable difference.  Doubling power doesn’t do much for output, just a few db.  The REF 75SE is such a great amp and design, I think it actually sounded better.  The design is so much better also for the bias.  Adjusting the bias on a 150 is a major PIA where you can easily check it whenever you want and dial it in on your REF 75.  I highly recommend staying with your REF 75 until you are ready to move to the newer amps.  I got the REF 160M a couple years ago and that was a definite upgrade over the REF 75.  I would expect the new 80S or 160S would provide a similar upgrade but stay away from the 150.  The 150 also has a more unpredictable resale value.  I bought one a few years ago for $4000 and have seen them also go for $8000+.  The REF 75SE has a very solid value around $5000.  If you could get an 80S for around $8000, I think that would be a great upgrade.
