    Thoughts on Benchmark AHB2 sound ...

    I think the amp has warmed up sufficiently. I'm using it with the Wyred 4 Sound STP-SE Stage 2 pre and an Audio Mirror Tubador SE dac. The Benchmark gain is set to its lowest setting and I am using it on my Avantgarde Duo XD.

    The benchmark AHB2 amp has some awesome qualities to it butis not sweet and warm. It’s very, very smooth, totally not aggressive, extremely articulate and it has powerful bass. It's absolutely and amazingly dead quiet with spooky details popping out of nowhere. Everything can be clearly heard and late night in the dark listening is a whole new experience. Itreally is a great amp but vocals could be a little fleshier and meatier. It's absolutely wonderful at low/medium volume like I love. Clear asa bell yet with zero fatigue. I have the tendency to crank it up too much when I love the song that's playing. Of course better quality music or high res is excellent. Lower res streaming, while good, is not ideal. Some songs sound better than others.

    I think adding a tube dac and sweet balanced tube preamp with balanced outputs, for my taste, would be a killer system.

    The jury is still out for it to be a long term only solid state amp for me but is in the top 2-3 so far.

    Re: Thoughts on Benchmark AHB2 sound ...

    Nice, sounds like it is a good match for you.

    I would think it sounds considerably different from many European brands, such as Goldmund/Job, T+A, etc. I think Benchmark gear is very dependent on your other gear.

    I know you love your Stage 2. I think taking the transformer out of the picture with the Hattor would really surprise you. I would love to know how it works with the Benchmark.

    Would be interesting to hear with the Chardonnay or even the upgrade model the Cabernet with a NOS set of 40's RCA VT-231's. That would give that meatier character you are looking for. Have you tried the combo with the Linton's yet?

    Re: Thoughts on Benchmark AHB2 sound ...

    Hi Jack,

    That was my thought with regard to the Supratek as well. I bet it would be stellar.

    Not yet on the Linton, but I did on my brother's pair of Harbeth C7 40th and it's superb. Absolutely amazing.

    Well that should translate. The Chardonnay and the Van Alstine SET 400 has turned out to be a good combo as well.

    Great on the combo. I've always had respect for Van Alstine.

    I have a few combos that I'm thinking of trying before settling down for a while.

    Re: Thoughts on Benchmark AHB2 sound ...

    Joe,

    Thanks for the wonderful description. Try it with your CJ Gat 2 and tell us what you are hearing. What are you waiting for?!! You have such a wonderful valve preamp in your stable.
    I have the Benchmark LA4 preamp. It is scary how close it comes to the Ayre KXR 20 in performance.

    Re: Thoughts on Benchmark AHB2 sound ...

    Congrats on the AHB2. I was a favorite of mine but sold it a few years ago. I will buy that again very soon. Would have been today if not for some unexpected car repairs.

    Yesterday, I bought the Benchmark HPA4 and the DAC3B. The HPA4 has the same sounding amp as the AHB2 but for headphones. I was planning on buying a DAC from an different manufacturer but learned of a synergy issue that would result in the HPA4 not running to it's max ability. That was related to the the type of interconnects used between the HPA4 (preamp + headphone amp) and the AHB2. It seems the Benchmark products run best when used with professional-grade XLR interconnects that run at 24 dBu. The other DAC I was considering, AudioByte VOX, of Rockna fame, ran at 12 dBu and was also noisier (SNR). Since I am picky about getting things wanting to run at there best, I went with the Benchmark DAC3B (not saying it is the better DAC, but better synergy). I will also use the very low priced Benchmark XLR's between all the Benchmark products since they are professional-grade (not consumer-grade).

    Just thought I would post as an FYI.

    Re: Thoughts on Benchmark AHB2 sound ...

    Thank you so much for your recommendation and congratulations on both the dac and the hpa4.

    There’s definitely a wonderful quality about the amp. I’m sure the other pieces are just as good.

    Interesting I have the LA4 too.

    Two others have similarly compared it to the mbl 6010d & Robert Koda (K10, I believe). The owners of the mbl and the RK own the LA4 too. It is not embarrassed in such company.

    The GAT2 with the Benchmark could be great. Gain on the GAT2 is pretty high but but with the selector on the amp, should be manageable.

    So glad you are enjoying the Benchmark Joe. It is always good finding a new piece of gear that you really like. I have been tempted by the Benchmark amp in the past and may try one at some point. I'd really love to compare it to the T+A which is similar in both size and pricing.

    Would like to try the LA4. When I had my AHB2 it was paired with with an Ayre KX-5 Twenty. I liked that combo except for the mechanical noise of the Ayre's volume control.

    I didn’t mind the Ayre clunking sound even though I often change volume a lot. I’m can get a little tiring.

    Re: Thoughts on Benchmark AHB2 sound ...

    The clicking sound when changing volume on a pre never bothers me. I actually prefer it because it is a feedback mechanism that my change requests has been received ... I know the Stage 2 does it as well as the Hattor. In the Hattor I suspect it is a physical changing the resistor path .

    Two years ago, when I purchased my Ahb2, I already had Shunyata Venom speaker cables-spade to spade.
    About a year ago, I purchased Benchmark cables-speakon to locking banana. After a 30 day trial period, the Shunyata cables were sold. No contest!

    Hi Joe, did you happen to try the AHB2 with the Lintons at any point? I've got the Lintons on trial but find something missing with them. I'm running them with a NAD C390DD and wonder how the experience might be different.

    Re: Thoughts on Benchmark AHB2 sound ...

    I returned the Benchmark at the end of the trial. Not because I didn’t like it but because I have a few amps that I prefer a little more. I do wish the AHB2 had a little more meat on the bone. I absolutely love the quiet and black background. It was totally different than I expected from reading the reviews. It was smoother and more natural but I feel it needs a very sweet tube preamp in front of it. Something like a 6sn7 type or similar tube.

    So unfortunately no, never tried it with the Lintons. I enjoyed it with the Harbeth.

    Perhaps it would offer more enjoyment with a tube preamp, but that’s a condition that shouldn’t be required of a good power amp in my opinion.

    As I think you know, I bought an AHB2 early on and before any reviews had been published on the rave recommendation of a fellow Avantgarde owner. It has some highly desirable features such as adjustable gain, is very nicely built and has a sensible price.

    However I found it decidedly dull – no sparkle or excitement to its music - and I wanted to turn the volume down rather than up – that’s never a good sign.

    Re: Thoughts on Benchmark AHB2 sound ...

    Hi Peter,

    The Benchmark spent most of its time on my Duo. I do a lot of low volume late night listening and the Benchmark was actually really wonderful. Spooky quiet with details emerging from nothing. It was quite remarkable and wonderfully entertaining.

    My SIT3 and especially my Luxman 590AXII are superb performers on my Duo.

    Something you should consider on your new Duo is the Luxman 590. It’s serious perfection. I could easily live with the 590 and SIT3.

    Re: Thoughts on Benchmark AHB2 sound ...

    Hi Joe.
    I've heard good things about the Luxman 590, but I don't think it's what I want. If I used vinyl or even needed other analogue inputs, it may fit the bill, but if I'm buying an integrated, it must offer digital inputs, even if no analogue is catered for.

    I tried the Bakoon 13r recently, but it's another "room heater" that I'd prefer not to have in my home. I'm not an Environmentalist as such, but I do have concerns about these inexcusably inefficient amplifiers. Same goes for the SIT-3 I believe - worse still as it offers no way of turning it off short of fiddling around amongst the cables to find the rear panel mounted power switch!

    In the EU, these devices are only permitted if fitted with auto standby (or off) circuits so they power down to 0.5W or less after a period with no input signal. My Accuphase is EU spec so has this feature, but I still baulk at burning 300+ watts to provide 5 watts of audio output. Peter

    Re: Thoughts on Benchmark AHB2 sound ...

    Ah, understood.

    I’m very curious about what you think of the M33 should you decide to demo it. That’s something I’d like to hear/own based on all of its features.

    Re: Thoughts on Benchmark AHB2 sound ...

    Hi Peter,

    I have read good things about the Bakoon amp. Could you please let me know what you thought of the Bakoon amplifier sound quality (heat aside)? Could you compare its sound to that of your Accuphase A36 as well as the NAD (I am very familiar with Accuphase Class A sound as I own the A70 amplifier).
    Thanks!

    Hi Anshul

    Please see attached sketch to see how I rigged my kit to compare results. Here are edited notes I sent to the dealer who loaned me the Bakoon 13r and Bakoon DAC-21 (now discontinued):
    I had the Bakoon units rigged up as shown and with power via the Puritan filer box and power cables. The NAD and Accuphase were rigged as usual – power via Isotek and Belden power cables.


    With volume levels matching I could use the Bakoon remote to select the 3 inputs in turn, but hard as I tried, I really couldn’t say that any one was better sounding than the others. Even the SATRI link seemed identical to the conventional RCA one. Viewing this with a cynical eye, one could conclude that if SATRI was really a better technology, then other brands would do things this way too.

    Then I compared the amplifier options, again as per the sketch and description below. I used my Silver Cabledyne speaker cables from the Bakoon and standard Chord Odyssey cables from the Accuphase or NAD.

    The Accuphase, as I’ve previously noted, is slightly warm / soft, so not my personal first choice. The difference between the Bakoon and NAD was so small one has to factor in the massively greater convenience of using the NAD. If asked for details I’d say:

    Bakoon has no balance control – OK for a power amp, but not so as an integrated
    No balanced input – minor criticism

    Speaker sockets are not colour coded – inexcusable

    The input sockets are bizarrely arranged – they should be grouped in pairs – and marked so you don’t need to turn it upside down
    The IR remote range is very limited, but this may be down to battery level.

    No Auto Standby after a period of no input. Surely this is incompatible with EU regs, particularly for such an extravagant consumer of power?

    The DAC-21 can’t be run from mains when the battery is too low – easily remedied as per Red Wine equipment


    The convenience of a single unit that can be totally controlled from the IR remote, or app on phone or PC is a feature I value, as is the need for no cables apart from speaker cables. NAD M32 wins.

    I’d like to get best performance from my system, but I’m sorry to say, the Bakoon units are not the way I want to go.


    I hope this helps. Peter

    Peter,

    Thank you for this write-up -- very helpful! I think I am going to skip scratching my Bakoon itch. Very eager to find out more about the NAD M33 amp.

    Just received the following Design Details document on the upcoming NAD M33. It's expected to ship in August retailing for $4,999 (US). One point of interest is that NAD is licensing the Purifi amplifier technology but are only using its power output stage. The power supply and input stage will be of NAD's own design and they'll be building the entire circuit including the licensed output stage in house.

    Like you, I purchased the Benchmark amp before a lot of the reviews were out. I have to disagree with your impression that the reviewers have reservations about the amp. The majority of the reviews that I have read have made the Benchmark their reference amp.
