  1. Hello and thanks for the link. In the past I looked into Deqx products but last time I looked they only do 24/96..like most similar units. This is one reason why I went Audiolense in the computer world to do corrections for higher sample rate music without down sampling.
  2. Thanks for the additional info. It looks like a promising option. Two concerns are there is no mention of supporting Linux. There is OSX support listed but I've come to learn that support for OSX doesn't necessarily mean support for Linux too (perfect example is the Hilo which is said to be USB compliant but yet doesn't work with Linux Distros..go figure). Also, I do wonder if that cable for the DB25 connection is available elsewhere for those who would need a longer length to the various downstream devices and what the output voltage is to drive downstream dac's. My subs for example would need about a 25ft run. Wonder if Mogami or someone offers a setup that can do say a few 6ft runs and a few 25ft runs with a single DB25 head to plug into the unit itself?
  3. Thanks Ralf11, I've not seen that DAC before and I will take a look. Much appreciated
  4. Thanks for the info Kal. I will look into that device from miniDSP and see how it works. Do you know if once the main USB cable from a music server is connected to the mini box if it then presents all those other channels to the Operating System to then be used as the User see's fit? As an example, if using Windows, if when I open the Sound settings in control panel would I see a bunch of Input/Out Channels available to use as I do today with the Hilo? Just trying to picture the outcome on the OS side of things once USB cable is connected...Thanks agian
  5. Hello, The best way for me to explain what I'm asking here is to use a hypothetical example. I'm curious to hear about why this is or is not possible or perhaps why its a bad idea compared to using something like a Lynx Hilo (which I have and use today for this same purpose). Mainly I'm looking for alternatives to the Hilo that can do most of what I need and ideally in a Linux environment where drivers are not needed. The goal would be to use this hypothetical setup with Roon/Roon Convolution in a system with 2 main towers and 2 subs (stereo sub config, not two mono's). The hypothetical system would consist of the following gear and be able to do/use the following features/software: 1. DAC's = 2 x Benchmark DAC3's 2. Interface between Roon Core server and DAC's = USB (one cable into each DAC, using two available USB Ports on music server) 3. Core server OS = Ubuntu latest LTS version 4. One 2-CH DAC feeds L/R signals to each of the Main Towers (2) 5. One 2-CH DAC feeds L/R signals to each of the Subs (2) Lets assume that the creation of the Room Correction files are handled via Audiolense which is also living on the same hardware as the Linux Music server Host where there is a Dual Boot Windows partition so it has access to the same two DAC's mentioned above. Signal sweeps and corrections would be done in the Windows Domain and the correction file that gets puked out here is then used on the Linux Host within Roon as your standard .wav files. Am I missing anything on why this may or may not be possible to implement? A few thoughts on what may be potential problem areas that have been tumbling around in my empty skull are: 1. Will there be an issues with having multiple USB DACS connected to the same Host when it comes to the music software gaining exclusive access to that hardware while stream files 2. Would having multiple two channel DAC's appear as individual output channels to the Room correction software and Music streaming software like they do today when using a DAC that has up to 32 Channels shoe horned into the same cable? 3. In Roon, today I use the 7.1 Channel configuration and manually map the 4 channels that I need while zeroing out the remaining 3 in the config file. Ok that's it for now. Don't want to make this wall of text too large just yet. Thanks for any thoughts/insights on this
  6. Going back to the old days when there was real rap
  7. Agreed on doing the physical placement first to the best possible location as determined by test tones at x-over Freq and SPL meter at listening position (mainly referring to bass region here). The better the physical placement the less processing is required to correct things. There are lots of opinions on the large woofer vs small woofer argument. Some say the smaller woofer requires more movement to reproduce the same output of a larger woofer and in turn this extra driver movement always equals more distortion. I prefer fewer large woofers properly powered over many small ones that may each be well under powered

  9. The difference is unimportant because both look equally horrible and appear to be built to return the largest profit possible back to their makers 😀
  10. The point of having an NAS in a home environment in my view is being able to squeeze as much performance/usable space into the smallest footprint possible that all other nodes on the network can take advantage of. A dedicated proper server smells "big" and "loud" to me and usually is if its being used as a storage node unless your dropping big bucks on an all Flash multi-TB, multi-Disk setup that is passively cooled and has enough CPU/RAM to take advantage of it all. Regardless of using a off the shelf NAS or a server for the same purpose I would still implement the same security layers previously mentioned since both are doing the same thing. They just now take on different footprints. My mini NAS runs FreeBSD/FreeNAS ([email protected] RAM) and every device on my network is Linux except for my music server which unfortunately must be Windows due to my first hop USB DAC not working with Linux at all (Lynx Hilo..damn shame & damn them for not supporting it).
  11. If I were in the market for a new router I would go with a Netgear based Tomato router. I've got an older one that still runs like a champ so I have no current need for a new one. But these things are VERY powerful in terms of what you can do with them. If you've go the motivation to toy around with it there is very little you can't do. https://www.flashrouters.com/routers/router-types/tomato/netgear-r7000-tomato-router I've spent quite a bit of time learning Linux IP Tables but its been worth every minute. You want to "TAG" certain PC's on your network to only be allowed to do certain things...you got it. You want very granular control of what any device on your network can do...you got it. You run a VPN and want to configure a "Kill Switch" if the VPN connection drops in the background...you got it. You want to run your own Open VPN server..yup you got it too. You want to run Dual/Redundant WAN services into your house and when one drops the other picks up seamlessly..boom you got it. I think you get the point. Highly recommended piece of kit!
  12. Ouch Indeed! These things (QNAP & any other like it ) should never be aloud to see/talk to the Internet in the first place unless the owner is feeling very brave. Same thing goes for IP security CAM's. Some people put all sorts of crap on these NAS devices and expose them to the web; sometimes unknowingly. Something storing your personal data in bulk (or watching you) should be placed in a bubble (separate VLAN) with EVERYTHING Inbound/Outbound blocked by default. Were talking all 65,5xx Ports on UDP & TCP. Then 1 for 1 pin hole access rules should be set up for "internal" things needing to access to the NAS on a specific IP and Port basis. Its a PITA to configure and maintain but in times like these its worth every minute spent doing so. People gotta keep $hit locked down these days or this is the result!
  13. Heh..it seems even the audiophile software vendors are now jumping on the Big Brother bandwagon. There's probably some shady deal in place to sell off your "anonymized" listening/viewing preferences to 5th parties in JR25. Its "almost" as bad as my Google Pixel phone harassing me every few hours that it needs access to the Microphone/Camera & Body Sensors in order to allow me to use the phone to dial a number 🙄
