What did you do to your stereo rig today?

I guess I had one too many beers last night sheesh. Sorry folks, didn’t mean to incite a riot! And Drew thanks for the offer, I’d love to hear one one day but no need to do that. I doubt I’d hear the whine in my listening room anyways, my neighborhood isn’t particularly quiet and there’s always a bit of ambient noise. I’m sure it would outshine a small whine. I wonder if it’s somehow mains power related. I’ve had equipment in my old **** house cause some weird stuff when mixed in with my electrical system
My statements were way more intended to dig on ASR than that benchmark as they seem universally liked.2 Channel in my home attic/bar/man cave

Finished up replacing the battery packs for my Musical Surroundings Nova Phonomena. I couldn't find the packs for sale anywhere and Musical Surroundings offered no help. Found a suitable battery pack on Tenergy.com. Ordered 2 for less than $90.
Michael Yee is definitely one of the good guys of this business. We exchanged numerous emails and he responded quickly and enthusiastically without any hope of remuneration. He helped me figure out how to connect the new batteries without buying a $300 crimping tool and also helped me align the light sensors that control the battery mode.
Now it's making very nice music in battery mode being fed by an Audio Technica ART-1 MC cart.

@invalid I think you might need to work on your reading comprehension. Here's my original quote:
"Because I'm one of probably under 5 customers of Benchmark that have EVER complained about this particular issue?"
I put the relevant word in bold for you. In this case "probably" means I'm guessing and theorizing. Whatever the number, it's surely low. As I'm sure you already noticed, there's zero results when Googling this symptom on the AHB2 and seeing any relevant discussions/complaints.
But just to ease your curiosity, I've emailed my contact at Benchmark and politely asked how many customers have ever reported this aside from me. Will let you know as soon as they reply.
@invalid Benchmark replied to my inquiry and said "Only a couple, including you" - Sounds like under 5 to me.
They also offered to put it on the bench and test everything out, noting that it could potentially be a bad/failing PSU. Great service. -
Hey, Drew. I would not be surprised if they came back and stated that a capacitor went bad within said LPS. That's cool that they have taken an interest in testing it.

SMPS, but yeah. I imagine some inductor coil in the standby SMPS is acting up and resonating at a specific high frequency. Could be out of tolerance, bad batch, etc.
"Coil whine" is a pretty big/well known issue among PC gamers using high-end powerful GPUs. In fact, many consumer electronics are now shipping out of China with coil whine, either while powered on or in standby. (KEF KC62 I'm looking at you) It's just something that not a lot of people notice/talk about it seems. -
Dunno Drew... A few plus you is like 3...
5 is a gross exaggeration by percentage increase margins 😝- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
A few, a couple, a little bit. Itty bitty, if you will.

Should have used a linear power supply in that amp.
-
Yeah if they did they would've prevented three customers complaining about a noisy standby SMPS.

Plus it would have sounded better. You were the one that bragged about how quiet it was on the linear power supply thread kind of funny. -
It would've sounded better? I wasn't aware you've tried one in your system, when was that?
-
This is worthy of another thread.
Are well built SMPS PS's noisier than a well built LPS or is it a cost associated, nose in the air placebo?

I've heard the benchmark in other systems, it's not bad, but always seems like something is missing, not my cup of tea.

Maybe a LPS? J/k (or am I?; not even sure if I know 😅)
I actually wish I could A/B the node 2i stock vs. the LHY LPS upgrade. Tbh, I subjectively felt like imaging improved, but that transparency decreased; not sure I like that trade. I ❤️ transparency.
Since I can’t A/B can’t really reach a conclusion, hence why I haven’t done a review.
Unlike when I purchased an outboard LPS for the Dacmagic, the LHY LPS from my perception is not necessarily night/day better.CD Players: Sony CDP-211; Sony DVP-S9000ES; Sony UDP-X800M2 (x2); Cambridge Audio CXC

Some people find the complete lack of distortion to be unpleasant/uncomfortable or simply not enjoyable in some way (it does take a bit of time to acclimate to it), and quickly go back to traditional solid state A/AB or tube amplification. It is what it is. -

There is no such thing as lack of distortion in an audio system, the speakers have the most distortion. Measurements are not as important as you think. we do not measure devices in the working conditions they are used, and we do not need a human weighting standard. -
I was talking about the distortion profile of the amplifier, and you know that.
But yeah by all means go off on a nonsensical tangent about how measurements aren't as important as I think they are and blah blah blah.
You're impossible to have a rational intelligent discussion with. * B o z o L i s t ' d * -
What I said is true, there is no agreed upon weighting standard, and we do not measure equipment in the working conditions they are used. Measurements are fine, but designers wouldn't even have to do listening evaluations if all that was needed is measurements.

That’s my issue with so many audiophiles (not aiming what I’m about to say at you, but speaking to the thought paradigm)…
Some say it’s all subjective, ignoring the fact that manufacturers do measure their equipment, and certain measurements clearly affect what is audible to most listeners…
Others say measurements are all that matters, and any perception that hasn’t been measured can’t be heard.

I have no idea. Those that rely on measurements only are a laughable crowd (to me). The statement in bold below used to be part of my signature;
~ Not all things that can be measured can be heard and not all things heard can be measured ~
Measurements are overrated IMO and can't tell you how the perception of imaging is changed, it can't offer any information on height, depth or other locational cues of the reproductive effort. Measurements can't tell you how the perception of space or the size of venue is observed/perceived to the listener. They are and can be a very useful tool for those who are not intimately familiar with frequencies, nodes and the like and how they affect the end result as to what hits your ears but along my audio journey, that's it. It's a guide. A useful one but one that has its limits.
I built my system guided by my ear, tuned it by ear, adjusted everything by ear and while I may not have achieved perfection (I never will), I damned sure have exceeded excellence.
Our esteemed member, @heiney9 has a quote by Nelson Pass in his signature that really puts a nice focus on this.
"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it. Differentiation by numbers is for those who do not".
It's like the measurement crowd needs confirmation bias to prove to them that something sounds good. That's why I stated that they are a laughable crowd.

I think measurements are important to verify a manufacture is putting out what it says it is putting out.

My contention is that there is value to be found in both measurementsand subjective listening experiences.
The laughable crowds (to me) are those who land in either extreme. Polarized views don’t make any sense to me in this regard.

Of course measurements matter, but there is still a big gap between what we can hear and what we can measure.

Depends on what?
Depends on whether what is being measured relates directly to that which may be heard.
For example, Frequency response variations are audible. The interaction between tube amplification and speaker impedance typically results in these types of variations and may be perceived by human hearing.
This has often been cited by John Atkinson @ Stereophile in tube amplifier reviews, as well as, speaker reviews.
It’s the same reason that modern surround receivers include room correction.

On the other hand, consensus among persons whom perform measurements seems to be that THD% measurements are far less audible , and chasing infinitesimal THD% isn’t a meaningful exercise.CD Players: Sony CDP-211; Sony DVP-S9000ES; Sony UDP-X800M2 (x2); Cambridge Audio CXC

I agree with what you say about most tube amplifiers, but there are exceptions to that rule, there are quite a few systems that have low impedance speakers that a few tube amplifiers had better bass than big powerful solid state amps. I've heard a few apogee speakers with tube amps that had better bass than my krell amp with my Apogees.
