A new trend on amplifier performance

[JSmith]

everyone knows equipment on a glass shelf makes the sound more clear

I find it more edgy, sharp and hard sounding. Maybe even sandy in some strange way... like something in the sound has potential to break and shatter, but doesn't. Oddly the glass shelf seems to have more of a bright sound during the day and a slightly darker sound at night. I might try a crystal one...

Spikes are no good, it's another of those useless inventions of the industry.

The advent of spikes with built-in vibration absorbers amuses me.

You just have to love how people tend anthropomorphize materials in this way

 

[sngreen]

most likely, but in theory microphonics could influence the electronics but if it is audible?

I have seen this mentioned by the reviewers, but as you say - is it audible?

On our bodies, we might avoid it but in hi-fi, we embrace it.

Now it's all starting to make sense. I always wondered why McIntosh used glass front panels? It was to project the sound forward. Then, coupled to those oiled walnut (or were they mahogany?) Panloc cabinets--making the sound more rounded and balanced.

And I always thought Frank and Gordon weren't in to this sort stuff. How wrong I was.

Surface under speakers, turntables and to some degree CD players - maybe - does have an effect on how the equipment sounds. That is what the spikes are for. For amplifiers it is mostly about the temperature (warm amplifier will sound better than the colde one). Wooden box on the amplifier will keep it warmer than the metal case, it's a known fact. Does it matter what it stands on, I have no idea.

If you mount the amp vertically everyone knows all the bass runs out the faceplate with nothing to keep it inside.

The question is, what kind of glass? Silica? Soda lime silicate? Boron? Chalcogenide? Float glass? Obsidian? They all will have different sound signatures, and What Hi-Fi should be ashamed of not telling this to audiophiles and publishing this highly incomplete article.

I needs to be multi-layered to correct for chromatic aberration.

 

[Blumlein 88]

Clearly, the sound will be more transparent and reflective of Artists vision.

It can only reflect an artist's vision if the glass is mirrored. Come on, I thought everyone knew this kind of stuff about hifi. What HiFi you ask? Exactly.

Some of the world's most sensitive metrology instrumentation comes in metal boxes with plastic feet and sit on particle board shelving all their useful life but ... yeah your ears are golden and microphonics are smearing your detail.

i wonder what the sound is like if you got a set of vestal virgins (I really dont know what this is) to rest your equipment on their arms?

it would have to be topping smsl high rack width 1 rack unit high and obviously not a McIntosh MA7200 etc.

Like the sound of one hand clapping.

I lost the other one building the damn thing

They aren't virgins at all. The gods have been cheated again.

Darko will not allow links from ASR......

I think I saw somewhere that Nordost is planning to develop an amplifier base from a machined 500kg pure @ 99.999% silver block. Grain orientation treatment in a special atmosphere controlled furnace and then cryogenized. MSRP to be confirmed. Looking forward to it

My dual mono ICEpower modules both disagree.

Only if the design dictates that optimal operation is in a particular temperature range. Heat kills electronics so there can always be too much of a good thing as well.

I might have mentioned this before: in my audio cowboy days I happened to be at my dealer when some new gear arrived. We were checking out the new Counterpoint tube preamp, from California. Counterpoint was a visual knockoff of the then famous Mark Levinson preamp--1 U rackmount form factor, which required tube sockets to be mounted horizontally, sideways as it were.

Anyhow, one of the cognoscenti thought he heard a little 'smearing' of the sonic image, when compared with a Conrad Johnson tube preamp (which had it's tubes mounted more traditionally, in an upright manner). His explanation was that the filaments in the tubes were not meant to be heated in a horizontal manner, and that this adverse mounting caused the electrons to 'bend or flow downward', and thus could have been responsible for the slight 'veiling' he (and then we all) subsequently heard.

Of course back then we were all audiofools. So I guess it made sense in a nonsensical way.

Just an image, but he said it number of times in his reviews;

Switching it off and on kills it too.

I guess the future Nordost silver base could be used that way too
