How close to the real thing?


Recently a friend of mine heard a Chopin concert in a Baptist church. I had told him that I had gone out to RMAF this year and heard some of the latest gear. His comment was that he thinks the best audio systems are only about 5% close to the real thing, especially the sound of a piano, though he admitted he hasn't heard the best of the latest equipment.

That got me thinking as I have been going to the BSO a lot this fall and comparing the sound of my system to live orchestral music. It's hard to put a hard percentage on this kind of thing, but I think the best systems capture a lot more than just 5% of the sound of live music.

What do you think? Are we making progress and how close are we?

Fas42, assuming the goal for all equipment is as much accuracy as possible, I do lay the entire blame on speakers. Solid state electronics can be designed to be, for home audio purposes, perfectly neutral, in that their noise and distortions are inaudible, and their frequency responses are flat regardless of load.

Speakers, on the other hand, are usually "voiced" Sometimes this is because the designer wants to achieve a certain "sound", but they are also voiced to apply judgment of how much high frequency roll-off the designer wants to apply to make the speaker sound natural in a room with certain absorption assumptions. I suppose you could argue voicing in the bass might also be necessary, because of room variations.

The latest speakers, designed with the latest driver technology and sophisticated crossovers designed with the latest software, can produce awesomely flat frequency responses these days. The latest speaker designs seem to have frequency responses that remind me of curves we used to see for amps in the 1960's. (Distortion levels too.) But lots of speakers are still "voiced" to sound a certain way according to a designer's biases, and the best drivers and crossovers (and cabinets too) are actually very expensive, so a lot of high end speakers still have response curves that look like saddles (too much bass and too much treble), and compromised crossovers that produce anomalies at the crossover points.

The differences in solid state electronics are far smaller. With tube electronics, one can design them to be as neutral as SS types (VTL comes to mind), but things like SET amps will have nearly unpredictable interactions with a particular speaker.
I also tend to believe that practically, in most well thought out real world setups, that a higher % of those using SS amps will sound closer to the real thing to me.

I say this based on the fact that I hear more variations from what sounds rel to me more with tube gear I hear and use than with (good) SS rigs.
I suspect that Mapman is correct for reasons coming from the other side. I have been surprised how my new Tube guitar amp changes character depending on how long it has been on and such. If I can change the source based on tube temp? than it makes sense that a tube output system may display this as well?
Paulsax, if I don't leave my ss gear on 24/7 it takes at least an hour to sound its best. With the high cost of tubes and electricity, few leave their tube gear on.
