The Paul Hynes SR4 PSU

[Apmusson]

Hi,

 

Great to see some familiar names in this forum @austinpop@str-1@TheAttorney

 

I'm thinking of buying a PH PSU.  I currently own a couple of Sbooster Mkii powering my Chord Hugo 2 in desktop mode and my Mscaler.

 

I'm thinking that an SR4T or SR5T or an SR7 might provide a good jump in sound quality but am really struggling to get any idea from the internet.  Usually I can find good reports and comparisons but I'm at a loss:

 

Is the SR4T any improvement in the SR4?

Is the SR5 or SR5T a big improvement in the SR4 or SR4T?

 

I saw the audio bacon review but a few of you guys seem to have owned a few of these PSUs.

 

Any advice for one confused potential purchaser?  Happy for a PM if you'd prefer.

 

Thanks

Thanks Rajiv,

 

Ill look through your posts.  I got frustrated as the PH PSU reviews have been low volume (like the units themselves).  I know owners are enthusiastic but that is the norm in HIFI land...

 

Thanks for your response.  It's appreciated.

Update:  I ended up ordering an SR4T in a fixed 5V version (for an increased amp rating at 4amps constant) together with a copper DC cable (6amp rating).

 

I'm scheduled for delivery at the start of May.  I've also ordered a Synergistic Research Orange 1amp Slow Blow fuse.

 

I'm coming from an Sbooster MKii Ultra setup which delivers 0.8amps (constant) so we'll see what the additional 'ampage' and Paul Hynes design does for my setup.

 

Thanks for all your comments above btw.

You may like to test out this cable. I was feeling a slightly better result with this one. It may be imagination 😀

I've ordered one - custom micro USB terminated. 😁

🥴 Count me amazed.

 

I've just added a SR Orange mains (230v 13a) Fuse to my Stax Energiser.  How can a fuse change the sound so much?  I'm getting immediate improved separation (amongst other audible changes - speed/tightness of bass)  - it's obvious and noticeable and doesn't sound artificial.

 

The reason I'm posting here is that I'm also planning to get one for my SR4T when it arrives....  Was there any consensus on using this fuse?

Have you got any comments from Paul Hynes about changing fuse on the SR4T ? (If ever discussed)

No.  Ive never spoken to him.  I wouldn't expect him to endorse or recommend anything which could cause a fault.

 

I'vechanged plenty of fuses and the fuse holder is placed to be easily accessible (see earlier posts from others - it just pops out of the IEC socket) without opening up the main chassis and I will use a like for like equivalent (1 amp slow blow rating).  I'm not concerned, if I don't like it I'll swap it back.

I received my SR4T 5v fixed this morning.  It is now installed in my system and settling in.  I have a Ghent DC to microusb cable as well as one from Paul Hynes Design DC6 gauge.

 

First impressions are good as an upgrade to an Sbooster MKII with Ultra MKII.  Out of the two cables I prefer the Ghent (thanks for the recommendation @R1200CL).
