lookin for 3D

cuibono · 21st November 2006, 12:27 AM

I've recently built myself a pair of SL's Pluto speakers, based around TI's LM3886 chips. I've modded them a bit, and am very happy with them. My only desire though, it to get more depth to the soundstage. Neglecting source and room changes, what could I do to the electronics to try and help this - or am I out of luck...

What effects the depth//linearity of low level detail anyway? Distortion?
Please, teach me..

Did you build them to SL's specs? The set that I've had in my room imaged like no other speaker I've heard (meaning really good).

Sounds more like room problems to me. I doubt you can do anything electronically. Read up on room treatment, there are several good threads here, or buy "The Master Handbook of Accoustics" by F Alton Everest.

I origionally built the Plutos to spec, and since then, improved them quite a bit by building a better enclosure for the circuits and upgrading almost every cap to BG or Auricaps. Any you are right, they are very good speakers. But not the best.

I have done a fair amount of room treatments, and set up in a number of different rooms. I will work some more on this, since a few people have suggested it.

In my head thougth, I'm thinking better low level resolution and/or better high power dynamics...

Is there any possible gain to the latter by increasing the PSU capacitance?

I wonder if the real lack of depth I feel is because my source is CD. I am comparing these speakers to a very expensive system using vinyl as the source....
