You are aware that no one can actually buy a 1.4 mR? That's a limited deal, just for you. No writer or blogger is going to publish a comparison of an unavailable product.

Wait, consumers are getting their micros upgraded to v.1.4, right, or (Jesus) did I misunderstand something here?

That's the big thing for me. It may be neat, but if people can't just purchase it, review time is better spent elsewhere. 

 

P.S. I may have something interesting to post tomorrow. The name Rendu is involved, but not micro or ultra :~)

FYI Ted B. has shown an interest in taking on the next review of the mciroRendu vs the ultraRendu.

I imagine companies like Sonore want a review to attract new customers who maybe read a bit about the microRendu but never bought one.  For them, the Darko review serves its purpose, and they will likely want the latest product.

 

Ted does excellent reviews.  I wish he did more of them.  I'm sure his review will be more comprehensive and useful to CA readers who are already somewhat familiar with the Rendu product line.

 

What I'd really like to see from @ted_b is a review of a Denafrips or Matrix Audio DAC with a comparison to the Holo Spring. 

 

@The Computer Audiophile, I'd also love to see a review of the Phasure NOS1a G3 from the perspective of someone unfamiliar with the evolution of Peter's work.

I am at a loss to understand why you guys think using a LIO (or a Teradak or an Uptone or a Hynes or a Teddy Pardo or a etc etc) was somehow unfair?  The LIO is as different a psu from what you guys use as his room is different from yours, or his ears, etc.  However, he used the same power supply for both products, and showed that going from the microRendu to the ultraRendu took sq from 7/10 to 8/10.  Nothing else changed.  Isn't that a comparison worthy of the word "fair" or "complete"?  If only using your own brand of psu is what you are looking for, my review will not be terribly different (LPS-1, JS-2, Hynes are my choices), and likely looked at as unfair too??  Help me out here, I truly don't get it.  Thanks.

 

 

 

It is unfair.  Why?  Cuz it's the best ultracapacitor power supply out there!  That's fact and not BS.  The impedance is the lowest it can be based on the actual ultracapacitor that's being used.  The MINI is similar though due to cap size.

sahmen:  Have you read about the technical differences between the microRendu and the Ultra?  The 1.4 micro just has the new clock, the Ultra, in addition, features no switching regulators and better board layout (for lower noise) because of the larger size of the board. 

I have heard both via the same power supply, there is no contest, the Ultra is a bit better, a significant bit (for audiophiles).  More very low level detail retrieval, a more palpable presentation, and better retrieval of ambience cues and low level decay trails.

Yes, I am with Sonore, so for sure take what I say with a grain of salt.  But I would say that John Darkos' comparison was spot on, he is clearly a good listener.  While the delta of the differences is a bit less with micro 1.4, the differences themselves are quite similar.

Lol...you may not know this, but, from the strict viewpoint of what I am trying to understand about the comparative sq performance of  the micro 1.4 as opposed to the ultra, you have ironically just provided me with at least one useful piece of information that I have not been able to get from anywhere else...  And yes, I have read at least John's description of the technical differences, as well as those that came with the initial announcement of the Ultrarendu, but there is no direct mention of the real world delta of sq differences between the Ultrarendu and the 1.4 either in those  descriptions or in Darko's review, which does not even mention the 1.4. In that sense, I find your description more "refreshing," even though your point about the "grain of salt" is also well taken. Thanks.

Have you heard HW 1.4 with the ISO regen? 

Are there any change is the sound at all ?

I was thrilled that he used the LIO's power supply. That combination should really get more press IMO. I'm a big fan of Vinnies work going back to the CAPS days and he has been involved with the Rendu series since day one.

We are actually calling it an update and I'll leave it up to the customer to decides if it's an upgrade:)

Nope.  Nothing against the work of Uptone, but I am one who believes in the KISS principle as much as possible.  As the Rendu series is specifically designed to have the best possible USB output (per John Swenson) I will not use add on devices.  I just use the best possible USB cable, and keep it at that.  In fact, I am currently looking for better USB cables, any cables I may try folks?

How about the Uptone Audio USPCB A>B adapter?

 

In my system between the microRendu and DAC, the above sounds better than either a .3M Wireworld Starlight 7, or a .7M Chord Co. SilverPlus USB cable.

 

The DAC currently in use is bus powered, so I can't try the little DIP switch on the adapter that defeats the 5v VBUS.

 

The USPCB might adhere to the KISS principal you alluded to in a "the best cable is no cable" sense?

@barrows This post may have escaped your attention, but this cable from Phasure/XXHighend maybe up your alley:

I specifically need an actual cable, .7-1 meter.  Why will become quite clear momentarily.  I found with the microRendu a really good USB cable outperformed the short adapters.  Best result seemed to be with the "Curious" very short cable.  I probably need to try a Curious .8 M.

Understand you need a cable rather than an adapter, but just wanted to mention:

 

I found the same as you earlier on (preferred cable to adapters), but none of the adapters was the USPCB.  I think UpTone put some thought into the design.  I prefer the USPCB to my longtime favorite, the Mapleshade Clearlink Plus.

You may be very surprised with Ghents JSSG USB cable. Give it a shot. It's  very reasonable priced ?

[barrows]

Understood, and good to know.  Thanks Jud!  I may experiment with some DIY USB cable attempts as well.  I am thinking unshielded data lines may have some advantages (less capacitance more "speed")-somewhat similar to Mapleshade.

Really? And how about this statement below?  Wait, I realize "update" is normally the word that is used in most of the official pronouncements about the 1.4, and that the word "upgrade,"  used in the statement below, might have slipped into your language when you were off your guard...  But really! Why all this effort to remain vague and noncommittal as to whether this "update" also constitutes and "upgrade"?

 

I have no ready answer for that, but I think you, sir, must probably run for office!

The world will never know because we are changing no more and no less than one part on this upgrade. I know what you want though. You want a whole separate board with a bunch of parts, connectors and jumper wires that uses more power. Sorry, but that in not what we are about.

I use a Y.F.S. (Your Final System) USB cable that, in my system, sounded better than Jud's longtime favorite Mapleshade.  I've used both 1m and "REGEN link" length with and without 5V.  Very similar to the Curious link I have.  Solid engineering, quality handmade construction and quick turn around.  Can be a little stiff.  I've used them with both my McIntosh D150 and Lampi Golden Atlantic DACs and it doesn't seem to impart much, if any, sound of its own.  Comparably priced to the Mapleshade Plus, which is much less than Curious.

The microRendu units that snuck in on Friday and Saturday for the 1.4 hardware update are done and will ship back on Monday. 

Sonore received my microRendu at 5 PM on Friday.  At 5 PM today (Tuesday) I had it back.  You can't get any better service than that!  Thank you, Jesus!

That was fast... If I may ask, how far is your zip code from DORAL, FL 33178?

I'm only about 50 miles away from Sonore, so I got next day delivery.  The point remains that Sonore got my microRendu on Friday at 5 PM and shipped it back on Monday.
