Can you post a screen shot of your signal path? How many dots do you have? What are you using between Roon and DAC, not that it matters but curious. Lot's of people swear that Roon Advanced Audio Transport (RAAT) sounds best. I've never had anything except RAAT on my "real" system so can't weigh in on how the bridge/streamer might impact things if it is not RAAT. All my non-RAAT stuff is spread out the house in non-critical areas. That said nothing in my other 5-6 locations actually sounds bad. What are you hearing that you don't like? Agree with @Thaddeus Smith if you don't want conversions you need a DAC that supports your chosen format natively. I've got a Denafrips Venus II, Gaia and Terminator + I'm "thinking" about selling. I have to get rid of one, just not sure which. PM me if you are interested in some back and forth dialogue. This is what one of my DSD/DSF files looks like. 3 dots is the least you can have....I believe.

When I switch form 2 to 1 I feel like the sound stage is a tiny bit wider and deeper, possibly a blacker background...but both are so close. When I go from 1 to 2 I don't feel like anything changes. It is only going from 2 to 1 that is seems like there is an ever so slight improvement. If I listen to either one for any length of time I can easily forget which one. I believe, If I were to leave the room and somebody else change it I could NEVER tell a difference walking back in.

I've switched them, that is connected the DACs to the opposite inputs. 1 to 2 and 2 to 1...so don't think it is the preamp channel. To be clear I don't really perceive it as louder, initially I liked it better. But the difference is so slight I'm starting to think it is a loudness differences, not actually an improvement or even a difference. I think most would agree that all things being equal you will typically "think" the louder one is better. Thinking it might be louder got me to wondering what would account for differences. Thus my post. Obviously a few differences on paper but very close. Same manufacturer, just two different DACs in their lineup. Seems entirely possible that as you move up any companies food chain they would up the output to stack the deck in their favor of more $$$ sounding "better". No?

I don't have the brain/smarts/vocabulary to answer that. Not sure what you are asking Preamp has 3 balanced (XLR) inputs. Each DAC connected via XLR to input 1 and 2. Preamp remote selects 1 or 2 as I desire. My streamer can output to both DACs at the same time in the same way while playing the exact same track at the same time. It does not seem to matter if I play FLAC 16/44, 24/96, 24/192 or DSD 64 to 256 files the one always sounds just slightly "better" but I suspect it is really a slight difference in volume.

I'm able to AB two DACs with the push of a button. I have a suspicion that the difference I hear is due to a slight Gain or for lack of a better term, "difference in loudness" between the two. I'm not very well versed with differences in loudness beyond Gain, and I can't find any specs on Gain. Not even sure if that is typically noted besides on preamps, again these are two DACs. Can someone tell me if these specs, below, impact the perceived loud/quiet of a device and if so which one should present a louder signal? If none of these below and Gain is not available, what other specs could impact the slight difference in loudness? I don't want to tell you which one I think is louder until I know about which one based on specs should...or if there shouldn't be a difference based on this info.

Using REW to Find Parametric Equalizer (PEQ) settings
rplace replied to Chris A's topic in Technical/Restorations
That looks pretty good to me. Only one wrap of phase and pretty flat. Did you plot the group delay and spectrogram? They can help with time alignment. Also, REW has a way to make snapshots of you plots and save as JPG so you don't have to take a picture of you monitor. Can be easier for looking at plots....but not necessary, just an JFI- 122 replies

Using REW to Find Parametric Equalizer (PEQ) settings
rplace replied to Chris A's topic in Technical/Restorations
Xilica makes that very easy...once you know how. If you are using the windows app not the buttons on the front of the unit there is a fairly obvious way to copy things. You select the channel to copy from and to, then a bunch of check boxes to tell it which items to copy. You want things like gain and PEQs but not mixer. Save your "good" stuff to a preset and if you mess up the copy just don't save it, reload the good one and start over.- 122 replies

Using REW to Find Parametric Equalizer (PEQ) settings
rplace replied to Chris A's topic in Technical/Restorations
I can't offer specific help with that, but I've done it enough times that it takes an hour or so...no longer days. General rules: Make sure the HF section is muted on Xilica or the amp is off Start with a clean, empty preset in Xilica so there are no PEQs set (this way you have your old ones saved) Level match the LF with amp or Xilica gain controls Set up REW to sweep from 20 to above your XO crossover point probably something like 20-500 to 20-1100 iteratively run sweeps and let REW tell you the PEQ values, enter them - try to lower not boost whenever possible. Try to get to +/-5 better yet +/-3 If he HF is fine and you have your old sweeps look for a place near the XO spot you want where the phase is close to each other. make that your XO point. Or perhaps a better way find the place the phase is close and let it tell you what the XO point is. Combine HF and LF, take sweeps with REW and repeat the PEQ entering process from REW to Xilica but this time on the input as a whole not the LF output side. Have a beer, listen a bit, repeat sweeps with both fine tuning the PEQs on input side until you are happy- 122 replies

You need to put a Beets Docker/Container on that QNAP and start obsessing over getting each and every directory/file named and tagged to the nth degree. I have not slept in a week. Loads of time wasting but perfect for the obsessed music fan. I went form this.... To This!!!
-
Not when you can get 001 and 002 AK6 for $25😜
-
Just like Roon I resisted for a while and regretted it. I knew Beets was the way to go but did not want to jump through all the hoops. I'm hoop jumping these last several days and all I can say is WOW. So powerful and so many ways to use it. https://beets.readthedocs.io/en/stable/index.html Start at about the 3:50 mark

PM me. I can explain how to extract ISOs to DSD files roon can play. Easy peasy. Have you figured out how to use Focus?

I think I did, in a round about way, in the 2nd post. Not sure I've heard the finest tube amps, but I've owned and heard several. I miss tubes from a visual point of view. Always fun to bask in the glow while listening in the dark. I don't miss hours of my life spent obsessing over what if there is just one more tube I've not tried and it is the magic one that parts the heavens. I fully realize that is my personality, not the fault of the amps/tubes. IMHO, @richieb is wise beyond his years (which are numerous) with all things amps. We joined the forum about the same time. He has probably had 5X the number of amps I have. Follow him down the amp trail and you probably can't go wrong. If you end up lost in the woods it will have been a fun trip.

I don't either but from what I've gathered reading on the roon forms there are a handful of DACs with multiple chips on them specifically designed for 5.1. with a little work you can make it happen. My take on it is there is nothing like pointing roon at your oppo and it just working. You need a specifically designed outboard DAC. I'm mildly interested in it but don't have enough multi-channel files to really pursue it. I know lots of people like it but to me multichannel music especially something like dark side of the Moon that wasn't meant to be that way feels gimmicky. Kind of neat at first but the novelty wears off quickly.

I have had the Venus II, Gaia combo for a couple of months. Not a huge difference over the Venus II alone.... I've written about it elsewhere on the forum. I was curious about the clock sync. So contemplated a T 2 when I found a local T+. Today is the day to switch the Gaia over to the T+.

Bi-amped mains and center. No passive XOs via xilica 8080. Carver TFM-25 x 3 at the bottom for 4 x Heresies surround L/R and surround back L/R. You can see 1 of the ceiling mounted Heresy peeking out with dual Crowns at the top of the rack to the right. Getting the Heresies onto the ceiling by myself was no small task.
-
If you pay the shipping both ways you will be broke. The Terminator + is a beast. I was worried it might not fit in my rack it is so wide/deep and heavy. Come out for a listen... might be cheaper.😁 Makes the J2 seem almost reasonable in size. I had to move almost every slot to get the silvers and blacks together
