ASR/amirm has opened my eyes.

[afinepoint]

Their mono kits won't be available until the end of September

 

[afinepoint]

From Nord:

We offer an amp based on the ICE1200AS2 £749 its stereo but you can use one channel and it will output 1200W
The M700 uses an old ICE module.
We offer far better options using either Hypex NCx500 or Purifi modules with our class A buffer that will perform far better than the M1200 at considerably less cost.
Mono block available.

The intent of Audiogon was to be a buying/selling space for high end gear. It was replaced by eBay and hasn't really been relevant for 10+ years. There are still some very smart people that comment there, but not as much as when it first started. If you have a sexy tube amp you want to sell for top dollar, it might just be the first place I’d recommend though.

I’ve been on audiogon for years. In fact, it’s where I bought my turntable years ago. The guy I bought it from was super cool and the price was right. So, I do browse there on occasion still, mostly to see what headphones are selling. In all those years, though, I never read the forums. Dodged a bullet there… lol

It’s about a thousand to 3 in terms of what Amir is up against over there but he does an incredible job of explaining what he does in a reasoned an well tempered way and he is just getting slandered left an right. Kudos for Amir keeping his cool in the middle of that snake venom.

There are some truly eccentric performances in that thread. Some of it is like a casting call for audiophile cliche characters.

Amir entering a thread like that is like Dawkins showing up at church service.

Seven years ago? This place didn’t exist, just marketing pap regurgitated in forum after forum, thank you Amir.

A forum called Computer Audio was a place I frequented for many years, from 2012 to 2020. It was a fabulous source of information. It changed it's name to Audiophile Style and while dong so created a separate thread for "objective" comments. i.e. if you have to talk about measurements do it here.

The home page is now covered in ads for extremely expensive gear and, like Audiogon, it has completely lost it's way. IMO the non objective threads are full of egos and nonsense.

I am truly grateful I found ASR, it has led me to some terrific gear at inexpensive prices. Our hobby needs Amir more than ever.

I've been watching Audiogon and a few similar sites for years, but even long before ASR was there, they already seemed mainly talking bullshit over there. I come from pro audio, and have studio and mainly live circuit experience as sound engineer, and so know the basics of the real electronic and acoustic engineering behind this all. Also, being a longtime fidler with diy repairs and builds (mainly speakers), i know how stuff works (at least the basics). And then it was not hard to see trough the bullshit. I may have a subjective preference for gear with harmonic distortion, but for the rest i'm glad ASR came (and a few other sites, altough less radical). Not everybody has that knowledge altough and that is why those sites had success. ASR is a big treat to them (that's why the hatred and attacks) because Amir and others take time to explain the basics in a way non-engineers can understand it. That is probally even more essential than all the tests he does.

I may not agree on you on the subjective part of the equation, but i do love facts, data and science based opinions, not a lot of woo and myths and snake oil. I know what my tube amps and class A amps do, how they colour (or distort if you wish) and what kind of distortion i like because i studied it on scientific methods. And i can also see why clean neutral low distortion gear is popular (and i even have some myself next to the coloured gear). Next to the tube amp and class A amps i also have a few NCore amps and a minidsp flex now, that i use where appropriate and love in the right setup.

This has caught my eye and for $1200 less than the $4200 I can get the PS M1200 for though 700 watts less. I wish this had a bit more horsepower.

What do you need all that horsepower for?

 

[Killingbeans]

Goldenear Triton One.R has a sensitivity of 92dB.

Unless your listening room is absolutely huge or you want the SPL of the music to be painfully high (or both), the 1ET7040SA will have plenty of headroom.

Or you’d like to destroy your speakers and/or your ears.

Doesn’t the thing already have a 1200W active sub? Surely 200W is then more than enough for the rest.

1500W. But I might not always have these loudspeakers.

I would dare to say that both Amir and I suffer somewhat from "Someone Is Wrong On The Internet" syndrome, and a place like Audiogon, particularly a certain coteri there, are like the Horn Of Plenty in that regard.

Hence, sometimes against my own self advice, I get sucked in to countering nonsense by the usual suspects.

I have that problem sometimes on the Hoffman forums. I avoid the cable threads since I don't wanna get banned.

I don't think so. You are gabby but it's mostly readable and @amirm does not pick apart everything like that kind of person would sometimes.

 

[afinepoint]

True. But I've heard an amp with greater Watts strains less at lower powers. Kind of a big block vs small block to use an automobile analogy.

But point well taken regarding the amp's load. It will be driving the mid bass, mids and highs. I made the same point with PS Audio regarding 1200W and the One.R having its own powered subwoofers.

Here's my part of a comment I made in a post I started in the PS Audio forum:

"Lastly even the PS Audio tech concured that for wattage the M1200s are way overkill for my loudspeakers. He still (of course) recommended the 1200s."

And some of the replies:

"Keep in mind that the “excess” power an amp can bring to the equation isn’t simply unused and therefore wasted. It’s been my experience that amps tend to sound their best when they’re far from being fully taxed, and they have substantial reserves of power for transients. So while the M1200s may appear on paper to be “way overkill” for your speakers (I assume he meant relative to your speakers’ sensitivity), the presence of that much extra headroom will make an audible difference, in my opinion."

"For whatever reason, 1200 watts is bothering you. It shouldn’t. Seriously.
I listen at under 1 watt of power going to the speakers. With 2 amps (monblocks), a preamp, music source, and 2 subwoofers, I use about 130 watts of electricity total when listening to music (according to my P12 regenerator).
My M1200 monoblocks sound WAY more dynamic than my 45 watt per channel tube amps, again, while listening below 1 watt.
The M1200’s sound more dynamic and sound really good at lower sound levels, and with much more “magic”."

"I was using the M1200’s with 97db speakers (until I recently upgraded the speakers), and the M1200’s sounded fantastic with them, and have a wonderful full sound at low volume. So I really would not worry about overkill."


It goes on and on.

So since I'm currently driving the loudspeakers with 750W/channel on tap now I thought to get closer to that. And yes I (still) agree with the PS Audio on the one point we both agreed upon that 1200W is overkill for these loudspeakers.

So Huffman forums is yet another anti-science audio forum to avoid.

I've also got to school myself on Op amp selection.

The choices for this Apollon purifi are Opa 1612, Sonic Imagery 994 Discrete and Sparks SS 2590 Pro. From least to most expensive. I guessing the Opa 1612 for no additional charge is the common choice. I haven't the slightest idea.

Have you downloaded the data sheets for these OP amps and compare them?

I'm banned on both btw, and i don't mind at all.
