I've been using the SR4 with the Silver DC cable (teflon coated) and it was always a bit on the bright side. After reading that the SR4 performs better with a high-end power cable, i plugged a spare Shunyata Sigma Digital cable into it and through the Shunyata Denali and everything snapped into place with much more weight and bass definition together with those accurate mids and highs. I am powering an EtherRegen with it and, yes, it is a tad "better" than the Ultracap LPS-1.2 it replaced and way ahead of the supplied power brick.

 

 

It sounds like you are saying that the SR4 needed a better power cord for it be a "tad" better the LPS-1.2 on the EtherRegen.  Am I interpreting that correctly?

 

I'm trying to figure out which power supply I'd like to purchase for my ER.

I upgraded my LPS-1.2 with the Ghent Audio Gotham DC cable which is probably why the SR4 was only a "tad" better in the lower end.

 

I already had the LPS-1.2 to run my UltraRendu and when the EtherREGEN performed better with a better power supply I needed to purchase another so I chose the SR4 this time so I had a platform for comparison. Either unit is good for the EtherREGEN and much better than the power brick that comes with the EtherRegen.
 

 

Thanks for that reply.  
 

I liked what I heard from Ghent’s Gotham cable with an LPS-1.2 previously, so nice to hear this benefited the ER as well as I still have this cable.

By the way Stephen from Paul Hynes LTD mentioned that the appropriate specs for the stock fuse on the SR4T are 5 X 20mm, Slow blow 1A so I plan to replace it with an SR Orange with the same specs. There are, however, conflicting views on the internet as to whether replacing the stock with an audiophile fuse with the same specs might be a good idea. Some say the replacement fuse must have a higher amperage rating for best SQ results.  Others (particularly the manufacturers) tend to discourage that idea of using a higher amperage fuse, and sometimes quite vehemently too, so what gives?

 

A downside with respect to the SR fuses is that the instantaneous inrush of current on power up can cause them to blow.  The next larger size is often ordered to minimize this risk. Only a Pass phono stage suffered this issue in my case, and I for many years I have uses SR fuses in all the components that have fuses.

 

I have never read a single report arguing that there are SQ benefits to going with a higher amperage SR fuses.  
 

I will soon be receiving a pair of Orange fuses for my amp.  Previously I went with the manufacturer’s rating and had no issues with either Black or Blue fuses blowing on power up.  This time though I went one size larger just so I didn’t have to sweat the risk of these blowing.
