The 2100 is home. Not near enough time to have much opinion. First impressions as the 2000 came off the stand and 2100 went on; they look an awful lot alike. Almost the same size except the 2100 is taller. Top plate, bottom plate, these things look identical. Power supply looks different. Bias trim pots better quality. Just some things I could see from the outside.
I tested the CD and phono so far. Again just initial first impressions. The phono has been improved. Sound overall is quite different to these ears. Lots of bottom end and with a different character. My suspicions it was a 2000 with meters have been alleviated. Clearly a different sound. When I get more time with it I will write more.
The remote is much better. Can choose source by individual button instead of back and forth click by click. Important first impression is it has more "umph" and nice highs. I dont expect it to blow away the 2000 since that was a great amp for me. we'll see.
An interesting listening impression, and thanks heaps for posting! One FET and one BJT amp!
The 2100 using FETS at the output. In the 2100 both l&r channel deploy a pair of n-channel power Mosfets. Two per channel of Sanken MLE-20 n-channel high power devices rated at 150w. The 2000 OTOH deploying six small wafer type bjt (TO-3P) Sanken 2SC6011 npn power transistors, again npn used for both channels. Yamaha of course have re-named these quasi-complimentary designs....."Floating and Balanced Amplifier".
I knew it was Mosfet but I thought the 3000 used more expensive transistors. Interesting.The A-S3000 is MOSFET same as 2100. Both amps use same devices Sanken MLE20 mosfets.
certainly is pretty. I have seen, but not heard all the recent Yamaha amps. Very nice in the flesh. I am soo glad Yamaha in their wisdom decided to retro-design their amps. It was a very wise decision I reckon.Thanks for sharing your impression of the A-S2100 and how it compares to the 2000. It's a beautiful piece.
Yamahaha, great review! I was really wanting to get your impressions compared to the 2000. I think I may have a buyer for my 2000 and if so I am going to pull the trigger and go for it. Thanks again for your insight, much appreciated.
Did you get one? Look forward to your take.
