  1. Hello, I dont disagree by any means that it would seem strange for the streamed version to have a separate pressing/version when dealing with an album that is only offered as one choice when playing and purchasing it from the provider. The test was done using Free software so its possible that the pieces of software needed to pull off the test are not as accurate as some high dollar dedicated piece of software might be. But thats just me speculating. I hear there are a few challenges present when trying to keep the playing field as even as possible for compa
  2. If someone wanted to have the best chance of finding out the answer as to why the streaming service version of a given album sounds different than a local copy of the same album purchased from the same streaming service then you would need to chose what you believe is the same version of that album as a starting point. An example being, the streaming service only offers one version for sale. You buy it and use it to compare the streamed version. The one part of that which you will never know is if both the download and stream are the same version (same catalog number, pressing..etc
  3. I've owned a few Pre's and almost bought a few others in my time in this hobby. I dont think you can go wrong with either of the Pass Labs Pre's mentioned (Almost bought the XP22 myself awhile back). The one brand I haven't seen mentioned yet is Ayre Acoustics. In particular, the KX-5 Twenty as far as something that is new. I've owned two Ayre Pre's in the past. The K-5xeMP and for a short time the original KX-R. In all cases, the Ayre Pre's were excellent across the board. The Audio Research REF6 was another I almost bought and listened to. It u
  4. Sure thing...given the answer you provided then I think my DAC recommendation is still worth a thought or two. The way I look at this stuff is almost everyone likes some kind of flavor of sound. We get to that point by usually mixing/matching various pieces of gear until we achieve the taste we like most. Each piece of gear could be considered a spice in the recipe (the sound we hear). Just like in cooking, too much spice can result in less than ideal meals...lol Anyway, I wonder if having the most neutral DAC possible in front of your Tube PreAmp would be the ideal set
  5. @chewynuts Hello and curious if during any of the various phases of system configuration you have tried, have you ever ran your system without the Tube PreAmp and went straight from DAC to Amps? Using other means of volume control of course (ie..Software based or perhaps builtin DAC vol knob). Your current equipment list appears to have at least two components that I feel can be ruled out in terms being blockers to achieving the sound you are looking for. Those two being your Amps and your speakers. Both are fully capable of that task. To me, this leaves the
  6. Found this after digging around for awhile about ZMAN's potential usage, specs, diagrams...etc https://www.merging.com/products/zman-oem
  7. Quoted from the Anubis product detailed specs page as an FYI in case you were not aware Redundant Power Options. Anubis is small and compact, it can be powered by its main PSU or/and from PoE (Power over Ethernet) making it a reliable redundant powered device. The input voltage range offers the possibility to use a wide range of power supply such as a battery.
  8. Here's mine I categorize the first four below as all being equally important. If a product fails in any one of those #1 priorities then it gets eliminated from my list even if it matches perfectly against all other priorities. 1. Does the product description advertise being able to do all the things I need it to do 1. How many documented cases are there around the web of said product where existing owners have confirmed that the product can indeed do all the things it was advertised to be able to do 1. Is it reliable and trouble free to operate 1. Does th
  9. Knock on wood my Windows 10 Core server has been working fine with Roon but the one Ubuntu Roon endpoint I use everyday at my desk (Intel NUC i5) connected directly to my Benchmark DAC3 via USB loses connectivity to the audio device like 3 times within an 8hr window everyday day. It all started after the 1.8 Roon update. Gotta close all my shit down and reboot the damn thing each time 🤬 Maybe Roon needs to hop aboard the AES67 boat and drop the craptastic Multicast RAAT protocol that only works on flat networks. They just took the easy way out for endpoint discovery pur
  10. Really there is no need for a dedicated streamer device when using HAPI or NADAC 8ch units or Anubis either. Since they have multichannel capabilities via their direct ETH ports anything that ROON can do or offers is directly available to them (ie..Qobuzz, Tidal streaming..etc). I guess my definition of a "Streamer" would be something like the Sonore devices, Briscasti m1, Aurender..etc..etc. I guess I dont consider the various multi channel ethernet based DAC's as streamers in the traditional sense because there is no need for a separate streamer when you use them.
  11. Hello, HAPI won't allow for that configuration as far as I am aware. I believe the "Audiophile" version NADAC has those capabilities though.
  12. Sure many folks do it that way. For my purposes I went a different route. I wanted a mic, mic pre and AD converter rig that could accurately cover the entire Freq range my gear in my room is capable of producing. I personally do not believe the USB pre/mic units are capable of pulling it off as accurately before running up against hardware limitations or other compromises.
  13. Thanks for the explanation on some of what ZMAN is meant to do. It sounds like for me I would not see any real value or use case for it. I guess if it were already baked into price of a given component that I was wanting to purchase I wouldn't complain but it would likely just collect dust either way from my use cases perspective.
  14. In my case, I am using Ravenna ETH in a very simple way without a Ravenna supported network switch involved. I have a home run ETH connection coming out of my Roon Core server via a second network card and terminating directly into one of the ETH ports found on the back of my HAPI DAC. The Roon Core server also has the required Aneman software running there which is used to configure channel routing to each of the 8 DAC channels. In addition, the same Roon Core server has the needed MAD ASIO driver installed as well which Roon uses to communicate with and identify the DAC and all its available
  15. Thanks @R1200CL, Yes I use Hapi as my primary DAC and use Convolution within Roon. The filters are created with Audiolense. I'm not sure what ZMAN would bring to the table if I had it but in all honesty I've not really dived into what purpose its meant to serve anyway. If its purpose is to allow one to have their convolution filters local to the DAC vs on a separate music server than that would be cool but I would be skeptical of that little processor board having enough...cough..cough balls in higher channel count systems. My old Intel i7 does the job fine but the serv
