Looks awesome

Yay!

Looks like you resisted the temptation to look at the innards?

Looking forward to hearing whether it makes a difference - hopefully after all that!

Can you give us the physical dimensions, please Antoine?

It's not as beautiful as our Devialets but I agree it does look awesome or impressive.  'Built like a tank'.

 To be honest I hadn't even thought about looking inside. Wanted to set it up quickly to still be able to give it a listen yesterday evening and as you read had to modify the 'lowboard' which slowed things a bit. I may open it later and when I do I'll make some photo's.

Sure, but keep in mind this four rail version of the SR7 is bigger than it's two rail version, which is bigger than the SR5, which in turn is bigger than the SR3. I only have the dimensions of my unit, they are approximately:

34.5x22.5x13.2 (LxWxH) in cm. These include the feet under the SR7 and the cooling fins on the front.

Pictures are in the last post of the previous page, in case you've missed those.

Hi Antoine, look forward to your first impressions on any SQ improvements that you feel the new PH multi rail PSU brings.

Clutter be gone! Removed all this from the system:

[attachment=1278]

Breeze Audio LPSU
HDPlex 100W LPSU
SMPS wallwart for powering the TPLink fiber to ethernet converter
3-way power distributor
2 AC power cables


The PH PSU is now connected directly to the PS Audio Power Plant and it's powering the microRendu, Mutec MC-3+ USB, DSPeaker Anti-Mode Dual Core 2.0  and the fiber optic ethernet converter. All four rails in use!

So I also modded my Mutec today and removed the internal SMPS and IEC inlet. One of the DC power leads that came with the PH is now soldered directly to the mainboard power input of the original internal PSU. This has taken me quite some time BTW, To remove and desolder the SMPS the entire board had to be removed from the chassis and thus I had to also remove all 10 nuts from the BNC connectors etc. etc. It also took me a lot of time to figure out how to remove the push lever of the female XLR receptor. Without this there would be no way to get the board out. Luckily I found a manual otherwise I would have never figured it out. http://www.neutrik.com/zoolu-website/med...es+chassis

This change is fully reversible should this ever be necessary.

The parts removed: (these look big BTW in this picture but this tiny PSU board measures only 6.8x4.7cm!)

All done now, time to enjoy the work! (though I already listened an hour or two just now )

Nice work, Antoine! I bet it sounds brilliant. For future reference, where did you get the removal too for the XLR receptacle from, or did you already have one?

Hi Antoine,

Where are you in terms of SQ with your super high level (and difficult to track through shipment) LPSU ?
Would you recommend others to modify their Mutec to remove the standard PSU ?

@Axel, sorry I missed your question; I don't have the XLR tool so I made one myself with, you won't believe it, an iPhone SIM card eject tool!   I needed something thin, flat and sturdy. After a modification to this SIM card tool I could remove the XLR lever.

Hi Swissbear, I haven't decided yet. Let me copy-paste what I wrote in a different topic in the quote below.

Unfortunately my NAS PC has died sometime last night. I wanted to listen to some music earlier today so got my iPad but Roon couldn't connect to it's database. It's been rock stable thus far so I walked upstairs and noticed the computer was continuously switching on, 3s later off etc. etc. 

Using parts from a different computer I've narrowed it down to the motherboard, an old Gigabyte with Intel H77 chipset. Motherboards with a 7 series chipset are no longer produced or available new anywhere in NL but I found a second hand Asus with Z77 chipset which I hope to receive Tuesday or Wednesday.

Quote:You're absolutely right, I still haven't shared any listening impressions of the Paul Hynes PSU yet. They'll come but since connecting it last week I've suffered "burn-in woes" (there's new regulator modules inside it) with the system clearly sounding different each day, at first bass was overwhelming, day later bass subsided to more normal levels but highs were a bit brittle so I'm giving it (or my brain ) time to settle. Since it's a power supply it's easy to burn in 24/7 by just leaving it (and the devices it powers) powered up. 

This week I also haven't had time to listen to my system and when I could have I preferred running my airco since it's been 30+ degrees here in NL. Overal though there surely are very positive changes I've already heard however I think the microRendu itself will be this years winner for me. This weekend I'll probably "check" again.

After a few days without my primary source I received the replacement motherboard last Thursday. With it I quickly got my 'NAS PC', running Roon Server, back up running perfectly again!

During the 'outage' I've updated the firmware of my Mutec MC-3+ USB to v. 1.10 and the D250 to 10.0.2.

Yesterday I've upgraded the power cord and fuse of the Paul Hynes SR7EHD-MR4 PSU. The fuse I have used is the same as in my PowerPlant P3, a HiFi-Tuning Supreme 3 (3.15A). The power cord I DIY'ed myself using Furutech top of the line stuff. The plugs I used are the Furutech FI-50 ® and FI-50 E ® (http://www.furutech.com/2013/01/26/949/). The cable I used is the successor of the well known Alpha3, the FP-TCS-31 (http://www.furutech.com/2015/04/17/10780/).

I'm afraid I'm going to disappoint some people who are curious to the listening impressions of the PH PSU but I'm not going to write about that after all. This for the sole reason I've changed too many things at once (all above). So I've lost track/can't really tell anymore what changed how because of what.

What I can tell you guys (and me upgrading the PH power cord and its fuse is a good indicator) is that the PH is not going anywhere, maybe ever again. It's been a roller coaster due to burn-in (never experienced anything as "capricious" like this!) but if it's performance as it is today (with all the other stuff surrounding it) is what it remains at or if it gets even better I'm extremely satisfied. So "sorry" about that but as it's powering four of my devices my impressions perhaps aren't really of use for anyone anyway.

Cliché but true: my system has never sounded better than it does now. It allows me to enjoy music endlessly and does exactly what I'd like it to do ATM.
