Linear Power Supply

Check out the two rail Uptone Audio JS-4.

I used the now discontinued JS-2 for my DAC and it worked well. The JS-4 is the improved successor model.

So to update the discussion.  I bought and have deployed a Linear Tuber Amplifier LPS; just added to the set-up.  In the first few hours, I can say there is definitely an increase and tightening of the bass.  Voices are more present and realistic. However, the soundstage is more forward and so far a bit fatiguing.  I am little suprised that it hasn't added as much weight to the music as I had hoped for. Hopefully with some more time and run-in it will settle down a bit.  I will keep the forum posted.

A further update; not so positive this go round.

As the air conditioning season has started in New England an unwanted feature has occurred.  When the AC ( central ) goes on, the LPS is faltering and the music stops to be replaced by static.  Our AC and my stereo cabinet are on different circuits.  This is a very reproducible event and does not occur when I go back to the wall wart power supply.  I did a bit of research and came across a couple of solutions: a hard start kit for our AC, vs a UPS.  Of course returning the unit is also on the table.  Any suggestions would be appreciated.

Give LTA a call.  Hopefully, they can diagnose the problem.

Just a guess - wondering if it might be a ground potential difference as the AC starts up.  Try putting a 3:2 cheater plug on power cord to the LPS.  See if it helps or not.  But don't keep the cheater plug installed over the long run.  Not safe.

Thanks for the advice.  I plan to call them tomorrow.

I will let you know what they come up with.
