Regulated Power Supply & Noise Floor
« on: 9 Aug 2012, 08:37 pm »
Hello,

I just scored some inexpensive Gallo Reference 3 speakers (something I lusted for greatly when they came out), got the wife to sign off on replacing the monitors in our living room, and hooked up my Sensation 451 (Sonicaps, bypass, 30v/130w PS). 

Really excellent sound quality as a I had hoped, especially once I remembered to undo the high pass filter and send a full range signal.

But I'd like to reduce the noise floor a bit if that's easily done.  So...  anyone here move from the 30v/130w switching power supply to a regulated power supply like the Alstron LS-10A and find a reduction in speaker noise/hiss?

Thanks!
Dave

Batteries are definitely the way to go if you want lower noise. They are very quiet.

Thanks, dboulet. 

I have to put the power supply on the floor so I want to avoid using batteries because I have two kids under 3 years old and can imagine one of them messing with it when retrieving lost cars, etc.  I'm guessing that would not be all that safe with batteries wired up.

I think I'll just stick with the 30v/130w switching unit.  It's really gorgeous sounding as-is so I think I'm all set.
