The Paul Hynes SR7

I guess the real magic sauce lies in Paul's circuit and design, which we have no access to. Another thread is a good start; but Uptone could probably also contact Paul directly to ask if he wants to license his designs out for manufacture. He's done that in the past with other partners, though always with him fronting the business.

 

I agree and think licensing Paul's designs is a great idea.

We'll look forward to that.

 

 

Quite right, thanks.

 

 

Any of you can start a thread in our forum I guess.

 

 

As @jelt2359 described, a good portion of what everyone seems to like about Paul's unit is that they are "bespoke" builds, based on individual user selection of options,be they number of rails, output voltages, connectors, wiring, etc.  That's simply not a business I am interested in getting into at all.

As far as Paul's very fine discrete regulator design, it is hard for me to picture licensing of it to be economically viable--for Paul, for UpTone, or for the users, since profits need be factored in.  Besides, John Swenson and I are not convinced that absolute lowest noise is required for a high-current PS.  Very low output impedance and lack of kicked-back AC mains harmonics are also important and our simpler choke-filtered designed accomplishes that.

 

I'll let you know once I've had a chance to compare my Paul Hynes to my JS-2 (probably late summer based on my position in the queue).

Paul told me earlier this week that he is about 10 days behind schedule due to a bout with the Australian flu but believes he'll be able to get back on schedule over the coming weeks.

My SR7 was number 4 on the list.  I received mine on March 27th but there was a delay in shipping and I think the SR7 was ready to be shipped around the beginning of March.

 

What are your early impressions?  What have you compared to it?

I've been enquirying with him a couple of times but have not heard anything back so far

 

That's discouraging to hear.

The enclosure is very well finished, but the top and bottom plates are quite thin and do resonate when tapped. There is a slight mechanical hum from the transformer, not surprising considering its huge size. Later on, I’ll try adding my HRS footers and damping plate to see if they have an effect on SQ or the mechanical hum

 

Thanks for the detailed review!  Please keep us updated on your damping efforts.

[auricgoldfinger]

I'm trying not to worry, but it does seem the completion rate is closer to one unit a month than one a week.

I'm 10 and haven't received mine yet.

 

Paul was supposed to begin work on your unit in early May according to the last published schedule.  Have you received a shipping notice yet?

I received a reply from Paul yesterday...additional delay is confirmed, +2 months in the best case scenario for my unit....but at least I'm re-assured that he's still working on the SR7 backlog

 

What number are you?

If someone is in your queue with many months to go, can changes be made to their orders?

 

I have changed my order several times along the way.  Paul says it is not unusual as people's needs change during the course of the wait.

[auricgoldfinger]

Paul does not include power cables with the SR7.

 

[auricgoldfinger]

Has anyone taken delivery of their SR7 in recent months?  We haven't received an update on the build list since June 28th.

 

Also, what power cord are people finding work well with their SR7?

I got mine in July. 

 

What number were you in the build list?

[auricgoldfinger]

Based on my reading of the posts in this thread, no units have been delivered in over 3 months.

[auricgoldfinger]

@paulhynes Please provide an update to the thread on the build schedule.  In particular, please let us know how actual deliveries have fared relative to your schedule as laid out on 11 February.  My perception based on very limited (and perhaps, erroneous) information is that you are completing and shipping units at far less than the planned rate of one per week. 

 

 

[auricgoldfinger]

@paulhynes Thanks for the update. I'm sorry to hear you have been dealing with so many simultaneous difficulties. I hope you're able to regain a sense of normalcy soon. Hang in there.

[auricgoldfinger]

I was quoted £480 to upgrade a single rail SR7DRXL.  I presume the amount varies depending on the build specification.

So why do you think @paulhynes has this option in his PSU despite his goal is to supply the best PSU to his consumers?

 

A Teflon circuit board reduces dielectric absorption in the regulator circuitry and the Vishay Z Foil ultra precision bulk foil resistors reduce resistor noise and thermal drift to very low levels. 

 

Who has real life expertise, Paul Hynes or marce?

[auricgoldfinger]

What brand of audiophile power supplies has @marce designed?  Has anyone ever listened to one?  Are any published reviews available?  I would love to read them.

 

@marce @mansr Why are you guys even on this thread?  You don't own an SR7 and have no plans to buy one.  You also have nothing of value to add to the discussion.

[auricgoldfinger]

@Johnseye The thread is being hijacked. Please do something!

Anybody here that know the size of the chassi for the SR7MR4 PSU cant find it anymore?

 

The last information I have is W = 224mm, H = 130mm, D = 346mm but you should check with Paul if it is really important.

Has anyone with builds in the queue heard from Paul lately? 

 

He's not responding to my emails.

[auricgoldfinger]

I wonder if @paulhynes is operational again after the move.

Possibly a bit off topic, but I have a Mac mini server that was Steve Nugent (Empirical Audio) personal unit.  I now am using Laufer Teknik Memory Player as it's world class.  My server is really special, but it runs on a large Paul Hynes LPS unit.  I odn' have the specifics, but I can get them from Steve.  Are these units worth much on the after market?  

 

The market value depends on the specific model.  Also, they don't appear often in the after market, so there isn't a lot of price history.
