I'll be awaiting hearing about how he "showed us" over at the placebophile asylum.
Is 24-bit/192kHz good enough for your lo-fi vinyl, or do you need 32/384?

Not near enough grey hair, but yeah, similar to the (self assessed) elite aural athlete Olympic gatherings.

In audiophile circles, you're viewed as a hero if you can hear stuff that others cannot. In real life, you're committed to an institution.

The Zoom recorder has a 1/8" input for line signals. Although the preamp has RCA output jacks, they are obviously taking the signal outside of the differential domain. One of the advantages of running differential circuits is lower noise. My concern was thus increased noise in doing a direct connection since I would be loosing the differential operation, plus it was a hassle to pull the FocusRite from the studio. So I set up the Zoom. This particular preamp is about 25 years old, being one of the first MP-1s built and so is a little nosier than later units. The Zoom was simply placed on a table, but what I didn't think about is that there is an arch between the living room where the speakers reside and the table. Imaging detail is diffused by both the arch and the flat plane of the table forward of the microphones in the Zoom.

There is a hum in the recording- the hum comes from the furnace fan. Having lived in Minnesota (which gets cold) and the same house since 1971 I no longer think about it.

I was asked to record a quieter portion of the LP. The first cut is a good 6 db louder through most of the track. I did prove my point despite the usual remonstrations.

And you couldn't just hooked it up to a computer?  You're full of shit.

I live in a cold climate and since you said your home was built in 1971 I can imagine what that looks like and how loud the HVAC system is.  You aren't fooling me.  That type of hum (especially that of AC coil whining through the vents in a small home) is quite different.  A furnace is distinctive in its cycles and operations and most will just make a sound similar to large fan blowing air through the vents.  You just hear the air moving through, although you may hear the flames fire up before the blower turns on during a cycle.  Terms such as 2 ton blower going through vent systems that has a capacity of 2 tons has been brought up by AC & Furnace repairmen alike.  Did you purposely stay up until 3 am to record this as those usually when you get the most furnace cycles?

All the more reason that you're so full of shit for not using line in on a recording device, dude.

Which hospital dude?  Regions, United, Fairview, Abbott Northwestern?  Those all got psycho wards for you to visit and stay a while.

Any possible losses due to taking the signal outside of the differential domain vanish in comparison to losses inherent in taking it outside of the electrical domain and into the acoustic domain.

Look at it this way - the designer of your preamp obviously designed the recording output jacks for the purpose of driving a recorder, which is the task at hand.

If you have so little respect for the preamp's designer's implementation of recording outputs, what are you doing with the rest of such a piece of junk in your system?

Time to update your signature, delete all your vinyl rips and throw away your 32/384 ADC greynol. You need to buy a Zoom and rip your vinyls with the built-in mic. :))  :))  :))

Again, you're simply revealing your lack of understanding. Differential inputs are for rejecting common-mode noise*, which is rarely an issue in a domestic hi-fi situation, hence why it's uncommon.

The hole's getting deeper, it might be prudent to quit while you're behind?

* noise in the sense of unwanted signals, not noise in the sense of white noise due to unavoidable factors

Transform from a "LoFier" to a "HiFi" guy. Got a nice sneak preview of the kind of sound, those stricken with audiophile disorder are experiencing. You can't make this stuff up.  ;)

Behind??
In his mind he can go back to Dunning-Kruger corner and revel in victory with the inmates. He showed those HA LoFiers incontrovertible proof of silent HiFi vinyl, despite the usual remonstrations.
Its a heck of an effect. Try an audio fashion jewelry show sometime, its even funnier.

I had enough laughs when I looked up his MP-1. Might've cut it back in the '40s but two huge boxes and 16 valves just for a pre-amp? Even Mullard's didn't need half that many back in the '50s.

My! Those guys needn't us "remonstrating" against their shoddy, make-believe claims.

They need professional help!

That MP-1 preamp is made by a company called Atmasphere, which matches his HA user name. Does this mean that he is something to do with the company? Was his agenda all along to promote his preamp? Because if it was, then I think it has backfired.

FWIW, I don't think so. I believe he does use his name both as a nickname and for his boutique amp company. I don't think he had marketing or promotion in mind joining here.

I'd be more impressed with the resolution-reduced volume controls, except that I know what you can get out of a $3 chip these days...

Ok, but I take it that you do think that Atmasphere the HA member is indeed something to do with the company of the same name? Perhaps he could confirm that himself just so we don't jump to any erroneous conclusions.

Yep. He might be the founder of Atmasphere the company. I believe he posts under the name "Ralph" on audio-asylum.com:

Yes Clive, Atmasphere = Ralph Karsten.
He's the "silent vinyl" prankster. You should see his jokes about amplifier distortion at AA.  ;)

No, highly doubtful.
He's an audiophile. They exist in their own little magical echo chamber. Believe me.

Couldn't tolerate the Zoom recording and remastered it. If Atmasphere need the flac to impress your Asylum friends, send me a PM, price negotiable. ;)

There are some hilarious disconnects from reality on that link!

He thinks the difference between "high-end" and "Hi-fi" is that Hi-fi is all about money.
So "Hi-end" doesn't show a profit? Yeah ok, whatever he says.

And: if you have a Class A solid-state amp it will produce about the same heat for the same power (as valves/tubes).
Right, so the 707W of heater power (per channel) of the MA-3 is "about the same" as the zero-watt heaters in a 500W/ch solid-state amp? Ok, we'll just forget about that then, it doesn't count.

Actually, if he had a stereo pair of MA-3s running (1.414kW of heaters), he could turn the furnace fan off and not get 60Hz hum on his Zoom recording!

Don't be surprised when the 60Hz hum doesn't go away.
Is 24-bit/192kHz good enough for your lo-fi vinyl, or do you need 32/384?

By coincidence I looked up the user manual for the MP3 and google returned this link:

https://www.atma-sphere.com/Manuals/Atma-Sphere_MP-3_Owner's_Manual.pdf

(Executive summary: Please skip to the last line of the quoted  document)

Follow the link and on the second page you will find the following:

"You have purchased one of the world's finest preamplifiers and certainly one of
the most unique. It was over fifteen years in development and represents a
level of performance that others will be struggling to achieve for years to
come. At the time of this writing, it is the only fully balanced differential
vacuum tube design in the world and undoubtedly heralds a new breed. You do not
have to wait all you have to do is set the preamplifier up by following the
simple instructions in this manual.

Every part of the preamplifier has been extensively tested and engineered so
the product will perform flawlessly for years to come, with little if any
service.

Please read the manual carefully and follow the instructions closely. If you
have any questions, do not hesitate to contact your dealer or Atma-Sphere Music
Systems, Inc.. Here's to many years of happy listening!

Sincerely,

Ralph Karsten

At the 2:34> mark I can hear ticks, pops and noise, including what sounds like talking or maybe a tv going in background? WTH?  :)

yup- forgot to turn off NPR. There is also one spot where a slight tick is heard when the furnace went on...

Wait, are you joshing, or seriously, you recorded acoustically, rather than digitizing the preamp out?  :o
