What is the art of sound?

"Very low noise" also suggests that some noise exists ;)

I'm not saying the detrimental sonic effect is huge - it's simple a case of covering all bases for complete piece of mind. I am somewhat of a perfectionist :)

Noise always exists, no component available will not generate noise. I suspect a forward biased LED will be no noiser, and given the correct choice less noisy that the two diodes in series that Glenn seems to like using in his preamp cathodes.

I know that displays are particularly noisy which is why a lot of CD players and AV amps have a 'display off' facility, but I'm sure I'd be hard pressed to hear a connected LED effecting the sound. Given the level of mains borne interference, is one tiny little LED really going to upset the whole thing?

Oh, white pinpoint high intensity LEDs - they're the new blue LEDs. :)

Nick, I take your point. Glenn recommended it so I went with the programme. He's certainly not the type to do these things if they don't offer some benefit :)

Also, many CDPs offer a display on and off facility. I can usually hear a slight degradation in sound quality when the display LED is left on...

Anyway, LED or no LED the preamp sounds stunning. I will be doing a full write-up shortly :smoking:

Ah, yes, the backlight of a LCD is a different matter, they are often powered by a switching DC to DC converter so much more likely to do damage.

I know Ian certainly seems happy with his modified pre.

Thats funny he told me it sounds better WITH the blue ledsh:)

Aye, that's only 'cos you complimented him on his 'pish catchers' and asked where you could get a pair :lol:

Marco.

Dunno about that mate but it seems the whole Italian team played in their PISH CATCHERS last night:lol::lol::lol::lol::lol::lol:

Too right, mate. The Dutch could have played in clogs and still won!

That was a very impressive display of football.

I grew up listening to live music so I want the same kind of impact when listening to it at home. Its kind of impossible task but I am a lot closer I also want to listen to the music and not the sound of my system I guess for me as long as I am enjoying the music thats the main point I try not to think in terms of bass resolution etc they all matter but basically I want kick drums to kick harmonics to cut through tablas and cymbals to sound real and natural and music that can make the hair stand on my back

That's exactly it, John. I would also add that I don't want to hear the sound of my room. I want the recording's acoustic to take me to the venue, not a facsimile that doesn't sound like the original. That has been my goal for many years and I believe I am closer to it now than I have ever been.
