Recommended integrated amplifier for upgrade

Technics SU-R 1000 would be on my shortest list. Gorgeous looks, + modern GaN technology. I have owned a LSA 350 GaN amp for over a year, and love it, love it, love it. If the recording is warm you'll hear it in its glory. If the recording is not, you'll hear that too. But if all recordings sound warm, then it's a coloration.  Now you may like it, but it colors the really good recordings, too

I have and love the Pass Labs INT-25, but I wouldn't recommend it to drive the Sonus Fabers. An INT-250 def could and beautifully i'd imagine. I had an INT-250 driving a pair of JBL 4365s and loved it. I also really love Luxman - the 509x is great, I personally like the 590axII better (I have both) but once again Im just not sure how it'll drive those Fabers. The 509x on the other hand would have no issues and the first 8 watts are class A. As for Mcintosh, Im really diggin the sound signature of their new stuff - mostly solid state though. Ive heard the hybrids and idk they just aren't there. A bit muddy. My opinion. That being said I loved the MC462 with a schiit freya+ driving it. The MC462 also sounded great with a c2700 in front of it. One combo i wish i had kept - it felt so overwhelming though - so many meters and glass lol. I have a MA9500 on order now. Maybe that's an option for you - god knows it's gorgeous. Lastly Musical Fidelity has a really rich warm but clean and articulate sound - I would def check them out if you want quality and don't want to break the bank. They have some killer integrateds. And if you do decide to go Audio research - I LOVED my Gsi75. Another one i wish I had kept. Good luck on the search and please post what you end up getting.

Appreciate all your feedback .

Initially I was interested on ASR report, as I read more , I feel their review are biased. I got my first edition of Topping D90 replacing my decade old Cambridge audio DAC Magic after ASR review.

Thanks @snapoli2 for your Luxman recommendation, Luxman 590axii and 509x is above my budget of $6,000.

@wsrrsw Ya, I have subscribed to ROON, small and dedicated audition room setup (12’ x 12’) .

I can't speak to Audio Science's possible affiliations or commercial biases.  I'll be honest, though - I'm a litle biased against it.  The sheer number of reviews suggest that they are really just lab tests.

I did read the Topping review linked above.  His one paragraph listening test consisted of hooking up 1 speaker.  You may each reach your own conclusion as to the ultimate value of this lab test.
