- We should derive pleasure from what gives us pleasure. IF someone gets a
- bigger bang out of reproducing a 3.1415927 khz square wave "perfectly" with
- their audio gear, then they are well within their rights to search for
- the gear most capable of doing such. They just shouldn't chant "this
- gear makes the most lifelike music".

- What I've found fascinating is that my listening the past two months has
- shown me that the most "lifelike" sound I get from my system is from
- using the DSP with lots of "lesser equipment" driving the "other 5
- channels of sound". The fascinating part is I don't read much about
- the "highenders" even considering DSP.
-
- If I consider the subjective example where I went and listened to a
- blues musician friend play at a local blues club (JJ Blues in Mtn View,
- CA) and then came home and tried to get as close as I could to the sound
- with my home system. One method was to turn my main amp on VERY loud
- (which duplicated the 'difficult to talk while the music is being
- played' experience) and the other much more enjoyable method was to add
- the DSP with its "inferior electronics and speakers".
-
- Now you could ask me "which gives you more pleasure: listening to a CD
- with just your two highend channels or with 5 additional midfi DSP channels?"
- My answer might surprise you. Some days I prefer the more lifelike 7
- channel DSP sound, but most others I prefer the easier to listen to
- 2 channel sound - maybe because I ENJOY listening to cymbals decay, base
- thumps decay, identifying individual instruments, whatever else I feel
- like listening for.
-
- I'll add one more experiment (accidental) that I did last week. I had
- just purchased Vols 1 & 2 of Chesky's Jazz Sampler and test CDs. I was
- cooking dinner in another room of my townhouse while I had the CD
- playing for the first time (system is in living room) and a piece came
- on that all of a sudden made me think "boy, that sure sounds like the
- Yamaha E1000 is on one of its DSP modes". I went and got the CD booklet
- and sure enough the recording was done in a famous jazz club to show the
- effects of reverb. It turns out that the jazz club was the same one
- modeled by the E/A-1000 DSP chips!
-
- Now why don't we read more about DSP giving more "lifelike" recreation of
- music? Is this similar to saying one likes "Telarc", prefers Bose, or
- just has the nasty D word in it?
-
- >The fact that the majority of highly skilled and trained professional
- >subjective reviewer's find LP reproduction closer to the final goal
- >of life like reproduction supports my argument. The fact that CD
- >measures better awakens us to the existence of inadequacies in the
- >subjective model.
- >
- I don't think LP comes close to good DSP. Add good DSP to an LP and I
- might agree, but I haven't heard that yet.
