@jfrmusic Luxman and CODA are known to have great synergy with Harbeths. Take a look at their integrated amps and even separates. I would definitely not add another Benchmark. It’s not going to be on the level of your digital front end.
Benchmark AHB2 in Mono Block Configuration
Hi:
I've owned the Benchmark ABH2 Amp for a few years but am now considering one two alternative upgrade paths:
A New Amp or adding a second AHB2. If I purchase a new amp so far I like the Bryston 3BCubed which is a dual mono design with 200 watts into 8 ohms or possibly the 4BCubed at 300 watts. In either case this is more power than the single ABH2 at 100 watts into 8 ohms. However adding a second ABH2 increases the power per channel to 380 watts .
So much for raw power. What about overall sound quality? The Bryston 3BCubed got an excellent review on Absolute Sound as an amp that would require significantly more $$ to better. Another review I read easily preferred the Bryston 43Cubed (300 watts per channel) over the ABH2.
I'm in the process of completely upgrading my system after several years of the same components. I will shortly have:
An Aurender N20 Streamer into an MSB Discrete DAC with dual power supplies feeding the single ABH2 which drives my Harbeth C7es-XD speakers.
Everything will be new except the older ABH2. Hence the consideration of an amp upgrade.
Now Benchmark will tell you that adding a second ABH2 is only needed when the single amp clips. Other than that there is no sonic benefit to adding a second. I Ffnd that hard to believe. I would think having a second would offer improved soundstage, separation and possibly better performance from the speakers. So my question is:
Have any of you added a second ABH2 and if so what were the overall sonic benefits if any? Also any opinion or experience on the Brystons vs the Benchmark? Or any suggestions of a better upgrade path would be welcomed.

@jfrmusic btw worth exploring what folks use with this level of digital and your speakers on a Harbeth forum. |
You have insane source equipment roughly $26K retail. However, you're feeding this signal into a $3500 amp. This is a big system imbalance no matter how good the perception of the Benchmark is (yes, it plays well above its price). I would not scrimp on a new amplifier, considering it appears you have a healthy budget. The world of audio amplifiers is your oyster. Give the source components a chance to sing! |
You can easily try the AHB2 with the option to return. Is there anyway to demo the Bryston with an option to return it? Even if this cost a few hundred for the trial, it would be worth it. Ideally, you would have both for a week or so and then decide for yourself. I don’t think you will know how they sound to your ear, in your system, and your room unless your try them both. I have an AHB2 and have read many reviews and you might like either one better. The 4B3 is about $7500 and two AHB2 are $7000 so the reality is they are about the same retail price. At the end of the day, both are detailed SS amps with a great reputation so either way it will sound great. Please keep us posted because I may be making a similar decision some day. Given what you spent on the front end, are you going to change your speakers as well? |
I will check out Coda and Kidman. And thanks for suggesting the Harbeth forum. Yes the Benchmark doesn’t match the quality of the new front end. That’s why I’m looking for an alternative. My dealer carries Bryston. He has all the equipment I purchased so I can demo the exact combination in the showroom or borrow the Bryston for a few days. He doesn’t carry Benchmark. I just got the Harbeths and really like them. So they’re staying. |
