Do you consider yourself an audiophile?

[twentythreedom]

difficult to say how this particular one would work without measuring the room, but diffusers def have their place in a studio.

You're no fun

I like the German physicist bit. And it "preserves artistic integrity"

They mean "buy our amplifier please"

they used to use MOSFET transistors instead of err normal transistors (I guess) in guitar amps where they wanted to simulate valve sound. dunno the technical differences. They definitely never sounded/behaved like valve amps tho (not that you'd want a hifi amp to behave or sound like a guitar amp).

I've owned a fair few MOSFET amps and none of them ever sounded like any tube amp I've heard. I'd be sending it back if it did.
I'm still using an Arcam Alpha 8 and a set of Ruark Epilogue speakers for my PC audio, and it sounds nothing like the 'warm' (see 'distorted') sound you get from a tube amp.

I fear this kit is probably aimed at clueless people with money... oh... yeah... 'audiophiles'

my mission bookshelf speaker started rattling when i turn it up full, can i open it up and do the screws up tighter or have I blown it?

I had the same issue with my Mission's which I got ripped off for on Ebay (shill bidder ).

As soon as they arrived any amount of bass would make the front baffle rattle against the cabinet. had to send them off to mission to get re-glued. One of them is starting to do it again when lots of bass is being put through it I'm thinking of filling the tiny crack between baffle and the cabinet with epoxy resin - should sort the fucker out.

Audiophile piece of wood, anyone?

The most important component of any media room is the room itself. Many audiophiles spend thousands of dollars on components, while acoustic treatment is often overlooked. The AD 2 v.4 is a 13 root QRD diffusor (Quadratic Residue Diffusor), based on the mathematical calculation developed by German Physicist, Manfred Schroder. The AD 2 v.4 does not reflect or absorb sound, but rather it scatters sound in a predetermined 180-degree pattern diffusing direct reflections while maintaining dynamics. The AD 2 v.4 divides the sound waves into 13 parts. The AD 2 v.4 has an effective range between 950hz - 5khz. Core Audio Designs Acoustic Diffusor Collection is an elegant approach to treating a room while preserving artistic integrity. The AD 2 v.4 is designed to integrate within traditional and modern décor.

Diffusion panels are an important part of any well designed acoustic space. So while they look like a rather expensive version of one I think we can let that pass.

All good music rooms need a large wooden thing which no-one really knows what it does

I was told that Schroeder realised the design for acoustic diffusers after being inspired by the observation that light splits into a rainbow type effect on the eyes of flys.

I've been rehearsing with these guys who built the (10 room) studio we rehearse in so I've been hearing about these important bits of wood/stuff they stick on the walls and in the corners.

Yes that sounds like it! (except mine were £10 on ebay sorry). if it's just glue I'll glue it.

I sent mine to Mission because it would have been too fiddly to do myself and I don't have a high quality glue gun with a very fine nozzle/ very small to actually insert into the cabinet and go around gluing the baffle on the inside. I also wanted guaranteed, long lasting results!

I've seen friends Mission's rattly baffles fixed by jamming folded paper/ card in between the baffle and the cab...

So yeah, when the time is right, I think I'll be laying down my cabs with the baffle facing up and filling the baffle/ cab gap with some badass resin.

my mixes never used to translate well on home stereos and it was an endless fluffing about and back- and forth until I had my studio measured and panels / diffusers installed. I built most of them myself. now there's no need to check mixes at home anymore.
best 300 quid I ever spent.

 

[rutabowa]

the band is rehearsing with 4 drummers playing bits of sheet metal, 3 twin reverbs and an ampeg bass stack so i dunno how much difference it makes for us... but they say it's important.

for rehearsing it might just smooth off the sound a bit. the real difference is audible when recording and mixing.
sounds like a fun band btw!

It's more often the bottom end that catches people out. Getting proper bass traps made can work wonders.

exactly! the bass would always fuck me up, usually it was just way too much.
thing is, I got so used to compensating for it that I'm now overly cautious (often sub consciously) and the bass gets almost lost, so I actively have to tell myself 'push the bass, it's fine!'.

They definitely never sounded/behaved like valve amps tho (not that you'd want a hifi amp to behave or sound like a guitar amp).

I think the difference is that overdriven MOSFETS don't clip the signal the way traditional transistors do. But that's a hell of a long way from saying that they perform like valves. And anyway, assuming this is just a CD player, why would you be wanting an overdriven sound anyway?

think it was describing the amp wasn't it? anyway like i said i don't think they make anything sound like valves so i was just saying what they meant, rather than saying i agreed.

Ah, I may have conflated two posts - I thought someone was talking about a CD player. And yes, when I said "you", I wasn't referring to you, personally. More "anyone"

 

[rutabowa]

i did get mixed up earlier about there being a cd player too. the cd player makes no sense at all!

Surely not an actual real scientific fact??!! 111 It must be a first

Shroeder was in the grip of synesthesia, surely.

Ah the Audiophile wood company?! This is the same company/guy that sells a portable music player for wait for it....1680 Euros. http://www.tera-player.com/

The amusing part is that it doesn't even have a screen, you can't see what tracks you are playing?! It only plays wav format too.

The sad part is people actually buy the thing.....

Yeah but it boots in...

It's basically the worlds worst iPod

 

[ViolentPanda]

I think they're referring to the separate power supplies for the analogue and digital circuits.

This bit has me stumped, and sounds only a lot contradictory.



WTF do they mean by that?

From what I recall from long-ago arguments with friends on valve versus solid state, MOSFETs can be induced through overdriving them to "clip" the signal in a similar way to valves. Does it sound "valve-like", though? Not to my ears, and I say that as someone who's owned both types for amplifying instruments.

 

[rutabowa]

Don't think anyone can argue that solid state guitar amps can compete with valve ones....

Hey man, you can clearly hear the difference between 192khz and shitty old 96 kHz. Amateur.

Surely that site is a pisstake. All that engineering genius and web design from 1996.

I think it was the late Bob Penfold, from Practical Electronics magazine (and author of dozens of books on audio electronics), who went to the trouble of using a 'scope to analyse the waveforms, and found that while MOSFETS clip the signal flatly, valves don't just chop the peak off of a waveform, they do it in a sort of linear progression, progressively attenuating the signal so that what you hear isn't abrupt/harsh, it's a more rounded over-driven sound.
Bear in mind too, that most audiophiles will do almost anything to avoid over-driving their systems, so MOSFETs would make no real difference to them, except psychologically.
