I power the Ultradigital with a LPS-1 at the moment and this sounds pretty good already. Barrows told me the LPS-1 might not be the best partner for the Ultradigital

Any recommendations regarding power supply to the Ultradigital?

 

UltraCap LPS-1.2?

but seriously, the switching of the capacitors and the high frequency processor do not have a bad influence on the performance?  

 

Nope.  Not in the least.  And the once every 4-10 seconds alternating between the 70 Farad banks is 100% glitch-free and transparent.  I defy anyone to see the alternating on a scope.

Of course the other benefits— leakage--loop blocking, ultra-low noise, and ultra-low output impedance are some of what make the UltraCap LPS-1.2 the ideal mate to fine components such as the Sonore ultraDigital and ultraRendu.  And it doesn’t hurt that their aluminum cases match exactly.

Yeah, looking to go from SPDIF to optical....

 

I thought you were looking to go from USB to Toslink (optical).  At least that is what you stated in your e-mail to me.

There are many USB converters on the market that provide Toslink output (in addition to S/PDIF), but since the performance of Toslink is limited (by the standardly available transmit and receive parts), a lot of the better DDCs don’t include Toslink as it is not the usual choice for the target purchaser. 

 

It looks like your Meridian 218 also includes an S/PDIF input (on RCA jack right above the optical jack), so perhaps you can use that instead.

For anyone interested, after a weeks listening the  Ultradigital definitely sounds better with a 5v LT3045 before it powered by an LPS-1.

 

That's why the newer generation UltraCap LPS-1.2 has paralleled LT3045s as it output regulators.  The LT3045 did not even exist when we did the original LPS-1 design.  

I think you know all that.  Just posting for the benefit of others as there is no need to add outboard LT3045 DIY boards when an LPS-1.2 is used.
