John's system sounded fab the other day and he was using the stock PSU. I think it must be pretty good quality... If I get on with mine long term the PSU won't be something I look to replace but could possibly try a battery.

The supplied PSU is quite good I guess a proper LPS would be even better but need to be careful with money at present

Thanks, guys. Oehlbach seems to rate their PSU... ...which is why I asked.

I've been sufficiently curious about the Uptone EtherREGEN to take a punt on one, especially after chatting with Tony of Coherent this evening. Can you have too much reclocking? I don't think so, and this is further up the stream between the router and Asus streamer for me. I should be able to run the 10MHz reference clock from the Mutec, too. uptoneaudio.com/products/etherregenI'm going to order another Weiliang 12V PSU on eBay, the same model as I'm using to power my router, and run it from the P3 regenerator.

This should really work well with the Mutec I am interested in how this goes

I took an interest because it will optimise Qobuz streaming, which is my sole source. Because of their order backlog, I won't get it until mid-May but I'll give it a full review from stock to linear PSU to using the Mutec's reference clock.

I've had the Uptone Audio EtherRegen in my system for the last month now!
It has been on 24/7, burning in, together with a couple of Sablon Audio Panatela Reserva ethernet cables.
I first tried it on it's own, after having Pete's AQVox 'SE' switch in circuit and imho, it is superior and cheaper, than the AQVox switch, which is pretty damn good, in it's own right!
Switching from the EtherRegen's own internal clock, to a 10MHz signal supplied first by my Mutec Ref10 and for the past two weeks by Tony's modified Ref10 (while mine was sent back to Germany for the 120SE board/oscillator upgrade) brings a further impressive performance boost!
Internet radio has never sounded so good!
Streaming from Qobuz Studio, however, is a bit of a revelation, with deeper bass, vanishingly low system noise floor and a wider deeper soundstage with incredible detail coming through!
My upgraded Mutec Ref10 120SE will be with me tomorrow and I have another two weeks of 24/7 burn-in to look forward to!
My network chain at the moment, is BT Home Hub 2 > 1 metre Sablon Audio Panatela Reserva LAN cable > Uptone Audio EtherRegen > 1 metre Salon Audio Panatela Reserva LAN cable > dCS Vivaldi Upsampler/DAC.
I plan to squeeze the last drop of performance from the Uptone Audio EtherRegen, by swapping the supplied Uptone SMPS for my 12v dual-rail LPSU, modified by Tony, which will power the BT Home Hub 2 (grounded to an Entreq Silver Minimus) and the Uptone Audio EtherRegen.
Future upgrade to the network will concentrate on replacing the BT Home Hub 2 al-in-one modem/switch/router, with either a superior unit (I like the specs on the TP-Link 2800/Archer unit, which uses a Broadcom chipset, not the more noisy Intel chipset) or a separate modem, router and WiFi access point.
We will see where further experimentation takes me (there's bugger all else to do at the moment) and a Coherent dual rail QP1 will probably be on the cards!

Excellent, Steve. Keep us informed of progress. I've just made a deal with the eBay seller for another identical Weiliang PSU pushing 12V. Then I can have Tony breath on both with his magic-dust caps. I agree that my TP-Link router seems to be ideal for sound quality and a lot better than a BT Hub.
I had also planned on having my Mutec breathed on and will experiment with using its clock output. If I ever spot a Ref 10 on sale I'll grab it.

Martin You won't regret getting the EtherRegen. It's a really smart addition to a network, prior to the DAC. I've got Petea to thank for setting me off down this road, when he visited a couple of months ago and left me with an AQVox 'SE' with and two AQVox LAN cables to play with! Tony sent me a phase noise plot (below) from my upgraded Mutec Ref10 120SE this morning. It will have 48 hrs burn-in on it, when it gets to me tomorrow morning! Do I go for two 1amp slo blo SR Orange fuses for the Ref 10 120SE? We'll see! Mutec Ref10_SE_120 Phase noise plot by , on Flickr

Yep, I too loaned petea AQvox switch but my system at the time wasn't ready to show what it can do. It's ready now, though.

Steve, please feel free to pass the unit and cables on to Martin - using a long pole of course!

No need thanks, Pete. I have a plan and will not need another switch over the EtherREGEN itself.
I won't even need another MeiCord as I will use the LAN isolator as a short link between EtherREGEN and Asus streamer.

I was also looking at the EtherREGEN although as streaming is not my main source, it would only be an academic exercise I suspect. My main source for file-based audio is directly from a Fidata server to DAC over USB. I'm sure I'll weaken though!

I had been trying battery power with my Oehlbach reclocker but due to the 6-8V range was struggling to find a good solution. I bought a "5000 Ah" set of NiMH batteries but they did not last long enough before needing to be recharged for a day. Recently, I came across a 6V LiFePO4 battery (I use two 12V LifPO4 to power my monoblocks). Here is the link: NX 4.5 Ah LiFePO4. You can recharge it using a 6V lead acid battery charger. I bought this one: Noco Genius G750, which seems to work well on the initial charging of the battery, my multimeter showed 6.8V at the end of the charge. I added an in-line fuse (650ma that I had already) and a switch. So far, it sounds great and lasts longer than the NiMH batteries - I have not had to recharge it yet.

I am pondering about getting a reclocker atm. Two weeks ago I bought a Soncoz SGD1 dac to replace my Caiman (with dorado and CMos clock upgrade). The Soncoz is better in some respects but I miss the Caimans extended high notes that seem to hang in the air. So, should I accept that the Soncoz is more accurate or try a reclocker? The problem may be that the Soncoz does not have a way of bypassing its own volume control and I use a DCB1 unity gain preamp, so the signal is through two sets of volume controls.

What input are you using on the Soncoz and from what source? That will determine what reclocker to look at.
Have you tried the DAC at full volume with the buffer preamp as volume control, then the buffer at full volume with the DAC as volume control? All things being equal, and knowing how good modern DAC chipsets are at volume, I would have the buffer at full volume as long as the power amp doesn't overload or create hiss through the system. It needs a little experimentation.
Extended high noise, air etc. are definitely things that a reclocker can bring to the party and the Caiman does give a very good account of the music so you'll need to be careful that you don't lose what you've enjoyed with the Caiman.

Hi Martin, thanks for the reply. Source is a Squeezebox Touch. I have tried Toslink and RCA. Switching between the two, there is no difference. Tried all filter settings. The recommendation is to control volume with the preamp. I havent tried the other way round. I will experiment.

I don't know if the Wyred4Sound Remedy reclocker is still available but it looks the perfect device for the job.
On the Touch, have you installed the digital output optimisations which improve sound quality by shutting down analogue outputs and other unnecessary areas?

Post by covenant on Jul 21, 2020 10:17:56 GMT
Yes, tried the alternatives available through EDO but not tried USB. The OEHLBACH 13904 XXL MasterClock is the one I was going to try but there is little information available. The Soncoz has a jitter figure of 38ps so may not be beatable?

Post by MartinT on Jul 21, 2020 10:22:41 GMT
It's not the internal jitter of the DAC that matters in this case, but the jitter in the feed into it. That's where a reclocker wins.
The Oehlbach is a USB reclocker. I thought you were using S/PDIF which is why I suggested the Wyred4Sound unit.
