I think this is true, but it only applies to classical music, chamber music, maybe some folk and jazz which is recorded at/as a live performance. ...

I believe an amp with a differential input (aka long tail pair) is entirely reliant on the performance of the LTP if it's going to sound any good. ...

I think you might be referring to a circuit that Hitachi published for their complementary power MOSFETs. Maplin used to sell a very popular power...

Yes, I agree, different types of distortion have different effects on the music being reproduced. For me, minimising the most objectionable...

To argue that a hi-fi amp should even have a voice strikes me as bizarre. Sure, musical instruments are voiced to create a particular sound - and so...

Switch mode power supplies are very complicated compared to linear power supplies - at least, I think so. :scratch: They're operating at very high...

Err.....well, that's a very accommodating attitude and I'm not quite sure how to respond other than to say he played everything so loud - way beyond...

Maybe you should just read the lines instead of imagining what you think might be between them. The Guardian forum moderators thought your views...

Yes, exactly the point I was trying to make.

I'm not saying that we should tolerate anything in particular or be intolerant to anything either, I'm just pointing out that you appear to think...

I remember visiting one chap who demonstrated the difference in sound when he placed something underneath his CD player. Somehow he seemed oblivious...

Is this meant as a joke?

Modern capacitors - and I'm counting 15 year old capacitors as modern - such as encapsulated film types shouldn't exhibit any deterioration and...

It might be helpful and/or interesting to spell out what these requirements are so potential builders can look for suitable drivers in their chosen...

What would be the problem with "over" damping? I would want no resonance at all, therefore it couldn't be over-damped. I'd damp it till it was...

Get a Rothwell Simplex. I've paid good money for the privilege of saying that - so I might as well say it :lol:

Interesting. Which hi-fi rules do you consider to be bollox? I ask because I agree with Scotty when he says "ye canno' change the laws of physics,...

I wouldn't have any qualms about using one. The people who claim to hear a difference when they change a fuse in a mains plug might think...

Obviously, if you box in the woofer it is no longer an open baffle. I'm not sure how active EQ would defy the purpose of an open baffle though.

Yes, I think so. If you put one watt in and stand 1 metre away you'll hear 96dB. If you put two watts in and stand 1 meter away you'll hear 192dB. ...

I'm really saying that the bass limit is set by the size of the baffle and trying to compensate for a tiny baffle by using massive EQ isn't a great...

It seems to me like a very illogical thing to do. The bass effectively disappears because the "positive" bass in front of the baffle and the...

It may be useful to consider the failure mechanisms for loudspeakers. Firstly, a voice coil could get so hot that the wire literally melts, like a...

It is an active preamp. Having unity gain doesn't make it a passive preamp - it's still an active preamp. I agree. The two big advantages of...

Why "of course"?

Just as an aside, I think it's worth pointing out that - although rarely referred to as such - Quad electrostatics are open baffle speakers. I'm not...

This would be where I got the idea of RF filtering from.

No, you didn't mention RF screening, and neither did I. I mentioned RF filtering, which is something else. Shielding a mains cable wouldn't filter...

Here's a punch for IEC sockets without fuse and switch http://uk.rs-online.com/web/p/punch-die-combinations/0543614/ They've gone up in price since...

I've heard this argument many times, but it seems illogical to me. If the audiofool (your expression) mains cable is filtering out noise, why would...
