The Paul Hynes SR7

Recommended Posts

Ah , my brain us getting old, thats where i got my DC blocker from, i suppose you could ask for assembly into a case than just a populated PCB , its on offer it seems.

Really nice guy and well made...the product that is..

@austinpop if you think that would help with such a large in rush current. ?

 

Thanks again Austinpops, another great year for the thread. Your work is very much appreciated as always.. et al..

Thanks for the pointers to the soft start devices, guys. There is actually a "built in" current limiter in the PS Audio regenerators like the P12, on the outlets marked Zone D High Current, so I have that option.

 

More importantly, Paul is working on a solution to incorporate soft start in his future builds, so once he has it, I will send my unit back to have it added.

I have a SR7 and have a question. Several of my components are plugged into a Shunyata Denali Power Conditioner. Does anyone have any experience using the SR7 and Denali together? The option is to plug the SR7 directly into a dedicated outlet. Currently I have the SR7 into the Denali but am considering redoing things to try direct to the outlet. 
 

Any thoughts would be helpful.

My advice would be to try both alternatives and go with whatever sounds best.  I know physically re-configuring a system can be a PITA, but it's the only way to know for sure.

Thanks for that write up and the photos. Extremely impressive job on that cabling, especially your tackling of the 24 pin! 

 

PHD really does seem to be thriving under the standard production arrangement with Stephen & co. -- I'm aware there will still be some desiring more esoteric builds from Paul himself and consequently facing the same issues with respect to very long lead times, but having a lineup of supplies available within a reliable timetable really helps make the value of their products more evident to more people. I've been so happy with my SR4T that, only five days in, I'm considering doubling down and placing another order.

@Iving

 

Congratulations on your SR7T, and I, of course, am not surprised to hear of your positive experiences. I thought I'd suggest one more experiment for you to consider.

 

Do you have another "good" 12V PSU available - for example, an LPS-1.2, SR4, Farad, etc? If so, use it to power the EtherRegen. This frees up the 12V/12A rail on your SR7T to...

 

...independently power the CPU via the EPS (8-pin Molex) port on your motherboard. You'll of course need an XLR to 8-pin Molex cable, or an adapter from 5.5x2.1 barrel to 8-pin Molex. Ghent Audio can build you these.

 

The outcome of this experiment is not necessarily clear. I do know that independently powering the CPU via a separate beefy 12v rail does wonders to the SQ of the server. However, it is also true that the ER benefits greatly from an SR7-quality PSU, so you'd be downgrading the ER PSU relative to your current baseline.

 

Still, you may find that the net effect is better than what you currently have.

 

Thank you for your thoughts.

 

Being a reader of the "novel" thread I was aware of this possibility.

 

A sig. constraint is building cables. I make my own. They are highly shielded and end up stiff. They are precisely measured to hardware. What I am saying is that once I committed a good length of expensive Mundorf Silver/Gold plus extra materials to making the eR cable terminating in a DC barrel plug, I can't now easily re-deploy the same wire to a molex job for the CPU. I'd have to build another very expensive cable just to do the experiment. (And the first cable would be wasted.) So I kinda had to commit to one or the other - and this is the permutation I chose.

 

It has crossed my mind to get an SR4T for the eR and use the SR7T 12V for the CPU ... but (we have confidence in the HDPLEX 800W Converter, right, and anyway) I don't want too many such thoughts to cross my mind ... and my hobby fund is depleted!

 

If ever I do it, I'll be sure to post.

 

I sure hope to read other SR7 experiences on this Thread.
