  1. That makes sense for an isolation transformer. There is no return path from neutral to ground in the panel otherwise. The regulation also makes sense, since you want the return path to ground to be at the panel, and not get cut short Thank you for the context and information!
  2. Thank you @One and a half! I appreciate the quick reply. To confirm, leave neutral on the primary disconnected from ground, but connect neutral on the secondary to ground. Ground and shield should be continuous through the transformer (per the graphic). Can you add some color on the motivation/implications of leaving neutral disconnected from ground (except at the main panel)? Is the intent of connecting neutral on the secondary to ground to mimic the same connection at the main panel?
  3. Peter that is so amazingly thoughtful of you to offer! I meant what I said about being most sad about not being able to hear the unit. I ordered a new Lush^2 right after the theft happened and it arrived (at my office this time!) yesterday. I've been enjoying it all day today, and looking forward to trying some of the configurations mentioned here. Very very gracious of you to offer, but I would hate for this guy to be impacting you. I have filed a claim with my credit card company for the theft, so I am hopeful it will be covered. Very much looking forward to what Jay has to say about the cable!
  4. Folks, forgive the newbie question, but I'm lost a bit in the various wiring scenarios for the Topaz Ultra Isolation transformers. I've tracked down a 91018-31T and 91002-31 on eBay. I'm US-based (120V) so I have H2/H4 (neutral) jumpered and H1/H3 (hot) jumpered on input, and X2/X4 (neutral) jumpered and X1/X3 (hot) jumpered on output. My question is where to wire ground on input and output. On one unit, ground was jumpered to H4 (neutral) on input and X4 (neutral) on output. On the other unit, ground was only connected to X4 on output (not jumpered to H4 on input) Should ground stay floating from the primary and secondary, or should it be grounded to the secondary or should it be grounded to both primary and secondary?
  5. Yup, but need to file the police report in person. That’s a tomorrow project. TBD if insurance covers this sort of thing, or credit card theft protection.
  6. The Lush^2 must be crazy popular! Mine (used) got delivered today, but this guy snagged it off my porch about 10 minutes before we got home Hopefully he knows the what the consensus configuration is Kidding aside, the only thing more frustrating than having it stolen is not being able to hear it!
  7. If you haven't picked up the new release from Sound Liaison that dropped today, stop what you're doing and fix that This is a 1950's style recording, but with modern gear. Incredible musicians, but an even more incredible "In the room" experience
  8. FYI, my server and my end point both boot from the Optane to RAM, with no issues at all. I still need to ramsave, except for the Roon DB that I run off the Optane for my server. The only trick for me was to add the /var/roon/* directory to the exclude list in the ramsave script (I mount the data partition on my Optane to /var/roon)
  9. I ran Roon Server off a USB stick, but I had 16GB ram. My Roon DB is ~5GB, so very RAM hungry. I ended up adding a 32GB Optane. I boot off of it (vs USB) to RAM, but keep my Roon DB and some local music files on the Optane.
  10. Many thanks to @austinpop for taking time out of his recent visit to San Diego to join our little audio group for an lovely evening of wine, ceviche, geek talk about servers and networks, and fine music from Hugo mScaler + DAVE direct to single driver high efficiency speakers (Omega Super Alnico Monitors, Voxativ 9.87's with 4D drivers, and Voxativ Zeth's with 1.8 drivers). Very well timed for the same day that Rajiv's fantastic Hugo mScaler + Hugo TT2 DAC review got posted (we'll see if we tempted him with the DAVE I've only recently started down the road of optimizing my upstream of the DAC chain (couple NUCs, ISO Regen, etc), so we all appreciated the discussion on master clocks, network and power isolation, etc. MUCH to learn, but fantastic to be able to share the trails being blazed here.
  11. I would definitely recommend the Voxativ's then! The Omegas ($2k) are amongst the best bargains in Audiophilia (and amazing and well worth having for near field if you have a situation that allows it), but the entry level Voxativ Zeth's ($7k) are pretty amazing direct from DAVE. In normal circumstances, I have the Vox 9.87's for 2 channel, the Vox Zeth's are my rear surrounds, and the Omegas are in storage waiting until I have an office at work again (in a cube right now) so I can set them up near field.
  12. Thankfully, that setup is only temporary for audio nights (the civilians in the house are a patient lot, but not that patient We did not listen to the Omega/TT2 combo in near field so I can't answer directly (it's my buddy's TT2, alas, so I can't check right now). However, the effect of the TT2 on the Omegas is very different than the effect of the DAVE over the TT2 though. The TT2 really extends the tonal range of the Omegas, and brings much more presence and relaxed sound. It feels like a different speaker with the additional authority behind it. We also have within our group First Watt F1J and F2J amps, and they both had a similar transformational impact on the Omega (hard to believe they are the same speaker as what we hear direct from Hugo2 and DAVE). Unfortunately, even with the First Watt amps, you give up so much that incredible transparency that you get direct. With TT2, you have an approximation of that "full'ish" range speaker effect with the Omegas, but retain all that amazing transparency and detail. HMS obviously takes it to the next level, and the Voxativ Z bass driver makes it a no compromise full range speaker system that (for me) blows most conventional high end speaker rigs away (my previous speakers before going with direct driven speakers from Chord DACs were B&W 802d3's) Interestingly, Voxativ drivers don't get that extra extension from either the First Watt amps or the TT2. For them, the extra transparency and spatial detail (esp. depth and height dimensions) from the DAVE dominate the A/B comparisons. Those differences are also there with the Omegas, but the lift from the TT2 is so profound, that that is a VERY easy tradeoff for me to make. Once you've had a DAVE for extended amount of time, you really notice when that amazing depth and height detail goes away. For me, DAVE is still king (Rajiv's wallet was wise not to demo it , but the extra power and upgrade speed of the TT2 really brings something extra to the table for speakers like the Omegas.
  13. You mean like this? With Omega Super Alnico Monitors, we thought the TT2 was clearly a step up from DAVE (driven direct). They became more of a full range speaker and really benefited from the extra power. Any loss in transparency and spatial detail with the TT2 (vs DAVE) was more than made up for with better dynamics and presence. Whether with DAVE or TT2, the Voxativ Z bass driver was absolutely transformational. Esp. with mScaler, the quality of the bass (and the reality that those pristinely articulated low resonances brings to well recorded music) make music absolutely holographic. If you are direct driving Omegas from Chord DACs, I consider the Voxativ bass drivers an absolute must audition (and purchase) The Voxativ 9.87's (with 4D drivers) and Voxativ Zeth's (with 1.8 entry level drivers) both are better when driven by DAVE. They are more efficient and faster than the Omegas, so the extra oomph of the TT2 doesn't bring as much marginal value as with the Omegas. However, the way superior spatial resolution (esp. depth and height) of the DAVE really shines through with the Voxativs. The Zeths with 1.8's are surprisingly robust on the low end. They don't strictly need any supplementation in the bass, the the sense of physical space and presence you get with HMS and the Voxativ bass unit is quite remarkable, even with the Zeths. In near field it is no contest: go with the Omegas. The Voxativs are like sitting in front of a intense laser beam, whereas the Omegas are softer and more generous. In near field, the Omegas really achieve transcendent imaging (esp. depth and height), but the Voxativs are just too intense (for me). For more normal listening positions, Voxativs are clearly the cat's meow.
  14. I had a couple of these cables: Toslink to Mini Toslink Cable (6 FT - 2 Pack), Fosmon Digital Optical Audio Male to Male S/PDIF Fiber Optic Cord for Apple MacBook Pro, Mac Pro/Mini, iMac, Chromecast Audio, More https://www.amazon.com/dp/B06XDGMB1B/
