Yamaha A-S1200 + KEF R3 Meta + KEF KC62 — Good Match?

@kevron99 I’ve had the Yamaha as1200 for just under a year and have been very happy with it. It’s driving a pair of 1982 Polk monitor 10a with updates. Excellent sound quality that improves with time. It replaced a vintage Yamaha integrated and sounds equal if not better. 
My only regret with the amp is not getting the 2200, it supposedly has the same preamp as the 3200 and uses thicker occ wire. I doubt it makes a huge difference though. Also the price puts you closer to a Luxman which may be better. But unless you live in Japan, the Yamaha is a great value.

You’re asking for advice after you’ve made a purchase. Usually it’s the other way around but hope it works out.

Yamaha makes great gear and I think their industrial design in the 2 channel realm is really beautiful.

And no, all amps with good specs are not indistinguishable from each other. But I suspect JB likes that word, lovely as it is,

It's been about seven years since I've had a Yamaha integrated in the main rig. I wrote this post before realizing that I had the A-S3000 not the A-S1000 which compares to your A-S1200. However hopefully you will still be able to glean some insight from my experience with the Yamaha integrated amps.

I don't believe there are fidelity specs or sonic differences between the 3000 and 3200, only feature differences which I'm sure also applies to the A-S1000 compared to the A-S1200.

The A-S3000 had a nice sonic improvement over my previous Yamaha flagship integrated, the A-1000 from 1985. I know this because I used the same speakers: Infinity RS4b's. The only negative aspect of the A-S3000 compared to the A-1000 is the A-1000 had more power. The RS4b's are harder to drive than most 8 ohm speakers as the spec sheet has them listed 8 - 4 ohms. Power differences were evident on the volume dial where the A-S3000 was almost at 12 o'clock and the A-1000 was at 9 o'clock for the same audible volume level.

I would have been happy with the rig had I not decided to upgrade speakers. At the time, my thinking was if the amp sounded that much better than 1985 technology, what sonic improvements would the addition of new speaker technology add?

I picked a similar size box speaker with similar size double woofers, a midrange and tweeter to the RS4b's: Magico A3's. The A3's perhaps sounded a little better than the RS4b's but no where near what I'd heard at the dealership. My next move was to add a Dynaco PAS-3X tube preamplifier to the A-S3000. I picked one up for $500. The sonic improvement over using just the A-S3000 was incredible! It sort of bugged me that sonics were better with the addition of using inexpensive, old, tube technology versus using the retail 8k A-S3000 alone. Since then I've changed power amps three times and finally properly matched amplification to the A3's.

One other thing that impressed me about the A-3000 with the RS4b's was that sonics were very engaging at very low levels.

I would bet using efficient speakers with the A-S1200 would work out nicely.

that is a tremendous match. great buy. now go enjoy your music and stop fretting @kevron99 

A Fosi V3 would suffice and save you a lot of money, though lacking the bragging rights of the A - S1200.

@jasonbourne71, I had to send one of my PS Audio amps in for repair. I didn’t have another amp to use in the interim so I bought a pair of V3s from Amazon. I am not disappointed. I fully expected them to be disappointing but I can’t find anything to complain about. They are performing well with my Maggie’s. I initially thought that I would return them to Amazon once my PS Audio amp came back but I’m going to keep Fosi amps on hand.

I’ve never owned a Yamaha product before but I’ve always been Yamaha curious.
