  1. I think if you want to do the purist review possible that is intended to only uncover the SQ of something like a DAC then using Roon or JRiver's software vol control would be the best way to do it. Unfortunately there are certain components that you just can't take out of the signal chain for obvious reasons to achieve the ultimate in transparency but that as they say, is what it is. With that said, I use Roon software vol control because I have to in order for my setup to work as intended. I was VERY concerned when I first started using it for some of the same reasons already mentioned by others but, knock on wood, it has worked very well thus far in the year or so I have been using it without incident. I do still though give myself an "Out" or for the purposes of "CYA" I leave the -10db Output voltage Pad installed in my Benchmark DAC which keeps the VOL knob active. Before each listening session and after initial power up I just need to remember to bury the knob before playback starts. This leaves me the option to quickly reach for the remote control vol/mute controls in case the software VOL decides to do something my gear or wallet won't appreciate If I could find an analog Pre that could do everything I need and have all the right Output options in the caliber of a Pass Labs XP-22 or better I would seriously consider buying one. I was in the camp of liking a good analog Pre in the chain and in most cases could appreciate the slight "seasoning" that it added to the recipe. But, thus far I haven't found such a beast within my budget so I'll be rolling with Roon's software vol control for the foreseeable future.
  2. What a great album from Tool IMO..Wish I wouldn't have waited so long to buy it. I think its probably their best one to date. Wow!
  3. Sounds good and makes sense. I guess the audiophile switch was too pre-occupied with removing veils to be bothered with things like passing packets 🤣
  4. Curious what Bit/Sample Rate convolution files is the Acourate program able to generate? I'm using Audiolense which maxes out at 24/192 and for this reason I Up/Down sample everything to 24/192 in ROON. Hilo does do DSD64 but IME it doesn't change sample rates worth a shit so this is another reason why I hard code everything to 24/192. Would be nice to have a multi-channel DAC that changes sample rates properly (on the fly). Also, I'm curious if you have tried to use the ASIO driver on the Hapi in a multi-client scenario? From what I've read its not multi-client which means taking measurements and doing playback of the convolution file will maybe not be possible.
  5. Hello, thanks for the info. Have you used this setup in a multichannel setup with for example a 2.2 configuration that incorporates 2 main channels & 2 sub channels that rely on convolution/room correction to function? Looking for actual end user experience that can confirm it does what it claims to do and functions 100%. I've seen and read about plenty of devices claiming such things but have not seen or read about any in actual real world use. Not saying its not possible or that anyone is wrong here, I'm just skeptical because of the lack of reported real world use cases on the web. As previously mentioned in my first reply Metric Halo 3D advertises something similar but then after digging into the details it appears to still be only half baked. I recall seeing one person post on the Roon forum about the device asking about how to get working in a multichannel configuration with convolution but after a few posts and no answers they fell off the face of the earth. In addition to having the playback software work with something like the Hapi the room correction/measurement/dsp and convolution creation software would all also have to work. I would love to hear from someone doing all these things that can confirm it does indeed check all of those boxes. (Edit)...and do all of the things I mentioned above in a Bi-Directional fashion Thanks
  6. Its been my understanding that almost no playback software I'm aware of know how to handle the multiple channels presented via an ETH connection properly....at least at this stage. I've seen option like Metric Halo who claim to use an ETH connection to present many channels over ETH to the computer/daw but it seems like the playback software support is not able to figure out how to use those channels over ETH compared to USB over ASIO for example (think ROON or JRiver here). Metric Halo (which only works with Apple) says they can do hundreds of channels over ETH assuming that the OS "see's" the channels as addressable and separate paths. But even if it does, I've not seen a playback software or room correction software knowing how to use them so that the user can map those channels to usable output paths for things like Subs, Mains and other channels. I'll admit that I could be wrong here but I have looked somewhat recently into this as I would love a ETH solution myself for my own Room correction needs. I currently also use a Hilo with Audiolense.
  7. Are folks setting up 10gb at home "Just Because" or is there some other requirement that is the motivation? I'm using basic 1GB connectivity for the internal LAN and see the following speeds between, in this example, my DAW and my NAS pretty much at all times. For a poor slob like myself this seems more than fast enough
  8. Any particular reason why you feel your network configuration is the cause for your less than great SQ? The description you listed looks pretty normal to these eyes (other than the fairly long ETH cable runs but each listed leg is still way under the limit of ETH anyway so probably a non-issue here). Whats the rest of the equipment chain look like?
  9. My NAS wasn't listed in the options so I didn't vote. I'm running an iXSystems NAS that isn't an "Audiophile" NAS.....its just a NAS. It uses FreeBSD for the OS and a ZFS File system. It works beautifully in any NAS like scenario and is very speedy. Not the cheapest option out there by any means but probably one of the best IMO. The hardware includes 32gb of RAM and a processor that escapes me at the moment but speed is a non-issue. My library is probably on the smaller side with just over 1200 albums and 15K tracks. The rest is my personal data all of which is under 2TB. If the need arises, I can pull hard drives and replace them with larger units to expand but I suspect it will be quite a while before I have such a need.
  10. I guess one negative against using the Alpha USB would be that it doesn't allow you to go straight DSD into your MA1 if that matters at all to you? I know the MA1 upsamples everything to DSD internally any way but its not really the same IMO as having DSD source material to begin with and have it pass thru unmolested. I use to own the v1 MA1 and used my WW Platinum Starlight USB to feed it with good success. Plus the Meitner works well in a driverless fashion using Linux based servers. With that said, I did own a few components that indeed sounded better using their AES Input vrs USB. To name a few they were Bricasti M5, Benchmark DAC1 & DAC3 and Lynx Hilo but using Lynx Hilo without its USB cable option leaves allot of flexibility on the table so I sacrifice and continue to use USB today despite this.
  11. I'm sure I am not understanding but how is this device a 5VA unit when the Input source assuming standard single phase power at 20A wall plug only generates 2400VA unless my math is wrong? It appears to also only have a 20A Input receptacle also. I didn't think transformers could create more power on the output than on the input unless they could somehow operate at above 100% efficiency ?
