  1. ELAC DMP-1 (aka Audio Alchemy)

    I'd not meant this as any review of the product, let alone one detailed in the manner that Chris or others provide. More of a suggestion. This system is a second of 3 that I have, the prime one using dCS Network Bridge which is far, far better in so many ways compared to the microRendu I'd come upon a few years ago. What I suggested is that the DMP-1 is more than worthy as a Roon Ready device, and with it's price point below $1k on the street, it more than holds its own against a comparably equipped microRendu. The DMP-1 does resolve the "cloud" of instruments/voices I hear from the microRendu. As for bass, it's no longer presented with mere energy but is delineated in layers. But, with all things, it's try and buy, which Audio Advisor provides (30 day satisfaction guarantee).
  2. ELAC DMP-1 (aka Audio Alchemy)

    I don't know how many have either tried or currently use this Roon Ready device, but having been a fan of Audio Alchemy and Peter Madnick's designs over the years, I though I'd give it a go in one of my systems. With such a good deal currently at Audio Advisor (should have more in stock soon at just under $1k), I brought one in for comparison against my existing setup: Sonore microRendu 1.4/Sonore Signature LPS/Yggdrasil DAC/Anthem D2V/Theta Intrepid/Revel Salon. After a 100+ hour breakin I started my listening. With the microRendu feeding the USB input while the DMP-1 feeding the AES/EBU input, I was able to pretty easily switch back and forth using Roon over the network. It quickly became apparent that the DMP-1 produced a more musical and focused soundstage though in many ways the two players are much alike. To be fair, I am using the optional PS-5 power supply ($595) with the DMP-1. On the other hand, I've been using the optional Cardas power cord into the Signature LPS along with the optional Cardas power cable to the microRendu, while the power cable into the PS-5 is just the one supplied by Audio Alchemy/ELAC. So, for me, the value proposition definitely goes to the DMP-1/PS-5 combo. I've moved the Audio Alchemy DDP-1 over to my iMac where it will soon be joined by the Sonore gear, along with a pair of Audio Engine HD3 and S8 sub.
  3. Article: dCS Rossini DAC Review

    I'm with Chris on his approach -- lights out and listen. Don't let other senses (especially visual) get in the way of the music and how it overtakes you. And like partaking of a fine wine, it's about the moment, a sensual snapshot in time. His reviews are that way, and unlike many others, not predicated on some scale or comparison with other components, but more about how the current experience moves him. Each of us has our own "tastes" in musical experience and listen for often very different things. Some for soundstage, some dynamics, some purity and articulation, etc. And it would appear that our choice of speakers often is the most revealing in what turns us on, as it is often the most colored component (apart from the room itself). I've got three different systems of varied components and value propositions and in varied "environments". There's the downstairs "reaching for the stars" system, the "hand-me-down" home theater (bits and pieces of prior systems), and desktop iMac/3-way speaker/DAC-receiver type. All driven by Roon on the network. I enjoy each, though they clearly present a different musical experience. I liken reviewers I return to again and again, like Chris, to those in film and music and the other arts. Over time, if I find a high level of congruency with one based on my own personal experience, they gain my trust. However the caveat, as others have said here, is that these are just components in systems, so its always best to bring one home for a try-and-buy in your own environment.
  4. micro/ultraRendu - support thread

    I've tested both microRendu units separately. On their own connected to at least 2 of my DACs they work fine. Issues I've run into are usually due to failing to unplug the power to the Audio Alchemy (not just turning off the unit via remote -- it's still "caching" status with the microRendu -- and then plugging the unit in after the microRendu is up and connected to the Audio Alchemy). If this isn't done properly the microRendu simply won't see the Audio Alchemy. And using Roon with either the Roon or Squeezelite app running works. So, the problem of using both microRendu units concurrently in my network still remains to be found. I've put one microRendu aside while I bring in another Roon Ready network player for audition.

    Thanks. Been through all that you’ve recommended with Eero tech support. And I did use reservations, which at least prevented the one “wandering” microRendu from changing its IP address, at times even when I was playing music! Last thing that happened is that I lost playback for both modes on the problem microRendu - Roon shows playing but the time indicator during playback never moves and I hear nothing. Happens for both Roon and Squeezelight modes. So, no joy.

    This is not a conventional router but a mesh network of peer access points (Eero). Essentially these are all routers and all devices are wired to them in my environment, except iPhone, iPad and a laptop. And I've tried various setups including using connecting the microRendu's directly to switches connected to the Eero and the one additional port on the Eero. Nothing's allowed both microRendu's to be seen by Roon as Roon endpoints.
  7. micro/ultraRendu - support thread

    Spoke with tech folks at Eero. They no of no reason why a mesh network or Eero in particular would affect the proper functioning of wireless or wired devices. Their position vis a vis placing the primary Eero right after the cable modem is the same as it would be for any WiFi Access Point (router) - in the event of ISP or cable modem failure, when service is restored putting a switch before the router might allow another device like a wired computer or printer to commandeer the IP address offered up by the ISP, leaving the Eero or a router effectively unable to function as DHCP server for the wireless network.
  8. micro/ultraRendu - support thread

    Modem is not a router. Simply has an f-type connector input from cable company Comcast. One output ethernet for connecting to computer or whatever. In my case I can either send it to the Eero wifi access point (router) input, and then use it's second and only other input as output to the Cisco switch. Or I can see if sending the output of the cable modem to the Cisco and connect the remaining Cisco ports to include the Eero. That's not advised by Eero support as it alters its function. Not clear how DHCP would change its function, etc.

    OK. Shut down the microRendu connected to the Yggdrasil. Used Roon to switch the microRendu/Audio Alchemy from Sqeezelite to Roon and started playing music. Moved the microRendu/Yggdrasil setup from home theater room to the downstairs audio room. Rebooted Nucleus/Roon setup. Once power was applied and the microRendu booted and connected to the Yggdrasil the music stopped playing in the other system. Rebooted the Nucleus, just in case. The Roon app still shows the Adio Alchemy’s IP address as network attached. However, when I attempt to play an album it’s proceeds, as before, to play nothing as it moves from one song to the next, finally ending. Same with any internet radio - simply refuses to play. If I now disable the listed network microRendu and use Sonicorbiter.com to switch the app to Squeezelite, the Roon app now displays the other microRendu IP address in Roon Ready list. I then enable it and attempt to play. It does but rather than playing through the Audio Alchemy it plays to the Yggdrasil. If if I change both microRendu devices to use the Squeezelite app, Roon only sees one, the Audio Alchemy attached. And it does play on that device. What now?

    The modem I have is just a Arris/Motorola cable modem connected to the wall then out to Comcast, the ISP. This cable modem is, as requested by the people at Eero, wired into the primary Eero wifi access point of the mesh network. The cable modem has just this one outbound port for use. From the Eero, a wire goes into one of the 3 Cisco 8-port smart switches, for use of wired devices close by: iMac computer, desktop microRendu connected to the Audio Alchemy, Obi200 VoIP phone unit, Apple Time Capsule, Brother printer, and Fingbox. The downstairs Eero is wired for the main audio system including Roon Nucleus core system, dCS Network Bridge for the Berkeley DAC, QNAP NAS, and Eero wifi access point. The other is located where the home theater audio system lives and includes the microRendu for the Yggdrasil DAC, a Tivo Roamio, HDHomeRun for OTA signal distribution, NVIDIA Shield video server, and Synology NAS video library. The distances between all of the Eero's and associated switches are long. Rather than trying to have long Ethernet runs, I decided to keep the switches and Eeros colocated with the equipment they serve. Though the downstream internet speed averages about 80Mbs, the Eero network (as measured by the Fingbox is running at about 130Mbs).

    No longer have any routers, just the Eero wifi access points, or the very lengthy cables I’d need to corral everything.
  12. micro/ultraRendu - support thread

    Don't know how much this might help but here is the full picture of the hardware: Roon core is running on their new Nucleus hardware. It is wired into one of 3 Cisco smart switches. Each switch has an Eero mesh wifi access point attached. This network is all local. Very little is available for configuration other than assigning fixed ip addresses to any of the network devices or enabling/disabling UPnP (currently enabled - I don't think this should have any impact on how the microRendu's or Roon behave). The only thing I have done in the past with the Cisco switches was to enable flow control so that the QNAP NAS providing music to Roon and onto the dCS Network Bridge / Berkeley Refence 2 DAC did not step on each other due to overruns. Each of the microRendu's is also wired into one of the other Cisco smart switches which in turn are wired to an Eero. The two microRendu's are a) updated version with 2.5 code connected to the Yggdrasil DAC b) original version of microRendu hardware also running 2.5 of the software and connected to the Audio Alchemy DDP-1 DAC Let me know if there is anything else I could research for you.
  13. micro/ultraRendu - support thread

    Since you suggested that there may well be some sort of networking problem, I decided to bypass using my connection from the microRendu to the Cisco 8-port smart switch and go directly into the Eero wifi access point that the switch is connected into. The Eero talks over wifi to the other Eero's in my network. Doing so created another interesting problem. Though the sonicorbiter.com web tools saw the microRendu and I could use the app switcher and other features with the microRendu, Roon would no longer see it on the network, even though it was advertising its existence. Once I shut down the microRendu and wired it back into the switch it was both managed by sonicorbiter and seen by Roon. Things are getting more and more puzzling.

    Just sent it to you at sonorejr@gmail.com. Let me know if you want me to send it to another email address.

    Another interesting thing: after powering down via software the problem microRendu / Yggdrasil system, I then used the sonicorbiter.com page to switch the other microRendu back to Squeezelite. As I did this, I could clearly hear the Yggdrasil clicking a change of some kind.
