View Full Version : "Warming" the sound a little on a SB2

Compared with my Marantz CD player (CD80) which has a decide "warm" sound, the output of the SB2 is somewhat cooler. This adds to the clarity of the sound and sometimes I am very pleased with this, but at other times it is a little bit too much on a system that already produces a very clear and transparent sound (transistor pre-amp and amp; Quad electrostatic speakers). Any ideas on how I might "warm" the sound a little (I am now using the analogue output), short of replacing the power amp?

go into AudioAsylum.com and visit the Cables section.

One thing you might care to try is to change out the stock switching power supply for a linear one.

I have compared a linear to the switcher. I felt that the sound of the SB2 with the stock supply was fairly harsh in the highs. With the linear supply the sound was smoother and more natural.

There are internal changes that can be made to the SB2 that would take it further along this path. Another option would be to try out an external DAC.

I thought about adding the Musical Fidelity X10 tube buffer stage: http://www.musicalfidelity.com/mf/en/Products/SmallX

Haven't had the spare cash to do it, yet...

Thanks for pointing me in the right direction. Perhaps I had better start with cables and take it from there.

Luuk,

As a very simple thing to do, just changing the external 5V switching supply (wall-wart) for a 5V linear will go some way to acheiving what you want.

Hi,

Are these linear 5V supplies something that can be picked up easily?

Is it any linear 5v supply we are looking for or are some types better than others?

Cheers

I'm not sure that anyone has identified a cheap, easily available
off-the-shelf model that fills the bill. If they have, I've not heard
about it.

The Bolder Cables company sells what looks to be a high quality unit,
priced accordingly.

Vinnie at Red Wine Audio will put you on batteries, among other things.

You could rig your own battery/charger system.

Other list members have been working on designs for what may become a
DIY kit or someone's product.

There was some discussion here a while back:
<http://lists.slimdevices.com/archives/audiophiles/2005-May/thread.html#290>

Enthusiasts at diyaudio and audiocircle are also hard at work.

Part of the delay in finding options for a quick and easy, external
linear PSU upgrade seems to be that the more talented and ethusiastic
designers and modders are setting their sights higher than that.
They're seeing bigger gains in more extensive internal changes.

For myself, I'm waiting to see how it settles out before carving up my
SB2 or spending big on an external PSU that may or may not work well
with whatever mods turns out to be The Way.
