Most here do not realize that everything has a sound.....everything makes a difference. I have spent over 45 years listening to wires, solder, resistors, caps, damping, shielding, etc into infinity. You can lose harmonics or add juiceiness, etc. from a solder joint.....a single one. The measurement people think that as long as it measures flat and has low distortion then it is neutral. Simply is not the case. I can take any amp....including the Benchmark and make is sound all over the place by modding it in different ways........and none of these things I do will change how it measures. Only those that have done these kinds of tests understand this. There are many audio companies that know some or much of what I say.....other companies and designers simply do not believe in parts and execution. What I believe in is what I BE LIVE......that is, experience.....and in audio that means how it sounds.
I could make the Benchmark amp sound more detailed and more warm and more holographic (more neutral, to me and most). No problem. However, it is too dang cramped to work on. Next!......and now we have a pure digital amp.....so, no need.
Most people who own the Benchmark amps have never heard an amp over $10K.....so they have no reference as to what is possible. If it beats their current $2K or $4K amp then they think it is perfect. Sorry......there is a big world out there. When the Hypex NC400 module was first released it became the darling of the measurement crowd "nothing will ever be better". Well, I modified it with better caps on the output filter (you can look up the sonic results still posted by several people on Audio circle)...and it sounded much better. So, was it "perfect" before or after I did the mod? Neither. Would not want a modded NC400 now.....yesterdays toy.
The guy at 10 audio.com loves his Benchmark.....However, he changed the fuse to a $150 fuse and he liked it much better (still his reference). I doubt he has ever listened to mega buck amps......but in the price range he plays in (under $7K for an amp).....he likes it best out of the very few he has heard. If I made a list of possible competitors under $10K.....I would have to type for a half an hour.....he he. There is soooooo much out there. Please try the $2000 pure digital amp from Peachtree......sooooo pure sounding....no dac, no analog cables, no preamp, no feedback or non feedback normal amps......less is more....
