Weird that there are very few comments on the phono stage in any of the reviews I've read. Has anyone seen any? This would be a great deal if it was good enough for me to sell my phono stage and my amps!

Also, Freo-1 I noticed you auditioned the TBI Millenia... Any comments on differences? I know it's apples and oranges but I'd actually be moving from the TBI to the Yamaha so it would be really helpful.

Regarding the differences between the TBI and the A-S2000, the take away is that the differences are significant.  The TBI is a low power amp, and has somewhat limited applications.  One should not use speakers that go below 6 ohms with the TBI, as it is just not designed to handle sustained low impedance loads.  Furthermore, the amp max output is 32 watts with a 24 V rail, and 18 watts with a 12 V rail.  It is not a good match for speakers that are under 93/95 db/w or so.  Now, some will state that they are using the TBI with speakers that are under 90 db/w, and my response to that is that the performance will be sub-optimal in that setup. 
A better comparison would be between the Pass Labs INT-150 and the A-S2000.  The Yamaha competes with the Pass Labs VERY well.  It is not easy to tell the differences between the two for normal listening.  One of the things I noticed about the Yamaha is that dynamic contrasts are slightly better subjectively with the Yamaha than the Pass Labs, which I contribute to the outstanding power supply regulation.  The floating balanced approach employed by the Yamaha ensures that there is no distortion crossover effects ever, since all the devices are N types in the output section.
Lastly, the TBI is Class D, and while it is a nice sounding unit, it still has some of the issues associated with Class D with regard to soundstage and HF (IMHO).

Does the Yamaha S-A500 compare with the S-A2000?  I have to imagine that
they use the same design and circuitry.  I'm interested because I have the
TBI and because of its low power I would consider the Yamaha S-A500 as
an alternative.  Also, like Freo-1 mentioned, the TBI is limited, but the
Yamaha has all the bells and whistles.

Actually, while the S-500 is a nice sounding unit, it's not the same design and circuitry as the S-2000.  The S-500 has a more pedestrian power supply, and is not a balanced topology.  The balanced design makes a big difference with regard to dynamics and increased resolution.

Thank you Freo-1 for your knowledge and input.   :thumb:  Sorry
to keep talking about it, but how does the A-S500 compare to
the TBI?  I wish I had the discretionary cash to afford the
A-S2000, but I'm a working stiff and can't afford it.  Although it
is nice to know how high the bar is and who knows, I might hit
the lottery.

  I took the top metal lid off and the top center metal piece off and the bottom metal plate off my Yamaha a-s2000 and then I put some ankle weights from Walmart under the front center and under the back of my a-s2000.

 After a few days I was shocked at the difference this had made to my system!

  You might want to try this out sometime and see how you like it.

  I also have a Audio Magic nano-liquid fuse in my a-s2000, it takes a 10a small fast-blow fuse and you might want to try one of these fuses too sometime.

I don't have much first hand experience with the A-S500, but I think it's a excellent buy. Here is a quick and dirty review:

Sounds like HiFiSoundGuy has improved performance by employing dampening to the chassis.  I'll look into this.  My A-S2000 is in a very heavy cabinet, so there is already some dampening.  The adjustable feet with the spikes heal as well. Do you use those?

   Using magnetic metal material for the top lid and top center metal piece and bottom metal plate that has the adjustable feet on it has a BAD EFFECT on the sound quality and by removing these metal pieces improves the sound quality a lot!

  The new Yamaha a-s3000 uses non-magnetic material for these pieces.

I used my A-S2000 with ATC SCM40's for a year and thought that I couldn't get much better sound without doubling my investment. In hindsight, I went from the SCM11's to the SCM40's and probably should have tried the SCM19 based on everything I've read. The ATC and A-S2000 combination--for a lover of neutrality and accuracy--was hard to beat. I would say that the A-S2000 is not capable of driving the SCM40's properly but could be perfect for the SCM19's or SCM20's.

I'm currently using the A-S2000 with Yamaha's NS1000 speakers and despite the difference in age between the two, they are getting along very well.

Freo.   We’re a year plus after your review of the A-S2000.  What are your current impressions?

The reason I ask is that this amp and CDP are on my short list.  I had the Yam CA-800 intrgrated back in the 1970s mated to some DCM Time Windows. A nice combo.   I sold it for separates a few years later, but always remembered how much I liked it.   So much so that I bought another one off Ebay.

I'd like to chime in here.  I owned the original A-S2000.  It was a good amplifier but not excellent; resolution was not top-notch; bass didn't have the slam I like; and the whole sound seemed  a tad soft to me.  I traded in the A-S2000 for a A-S2100 and wow what a difference.  The A-S2100 is in another category compared to the A-S2000. It has superior resolution, great bass and sparkling treble compared to the A-S2000.  It's as good a solid state integrated, as I've heard.  Yes, it's $1500 more than the A-S2000 but well worth it in my opinion.  I wonder just how much better the A-S3000 is at $7000.

My one complaint with the A-S2000 was the XLR input overloaded above 2.8 VRMS.  The matching CD-S2000 worked well with the A-S2000, but the Oppo BDP 105, not so much. 


I wonder what was changed on the A-S2100 to improve it's performance?  The preamp on the A-S2000 was rather pedestrian,  so maybe that is where it is improved.  I had tried the A-S2000 as a power amp with a Classe Preamp, and that did sound better than the A-S2000 straight up.


A couple of other integrated amps worth looking at is the Electrocompaniet PI-2, and the Sony TA-A1ES.

Opinions seem split on this amp. jim,  your experience mirrors the What Hifi review. But other reviews like the one linked to earlier in this thread,  and Freo`s do not seem to reflect this. Very curious. www.whathifi.com/yamaha/s2000/review

Hi Freo,
Though I am aware that I'm  resurrecting a dead thread, I would like to add my observations on my experience with the Oppo BDP-105D & the A-S2000. Since I own the Darbee edition & the A-S2000 (Mated to a pair of Wharfedale Dentons), I am happy to inform you that I have not experienced any overload/distortion on my setup in any way.
The reason for posting is that I was all set to NOT purchase the Oppo because of your post for more than a year. But then the lady of the house fell in love with the Oppo & I had no option but to get it. & I DO NOT regret the purchase one bit. Though I expected the XLR points to overload, I was happily proved wrong. Yes, it is the 105D & not the original 105.
Please treat this post as an FYI update.

Thanks,
Aaron
