[cross-posting this from WBF as I didn't get any replies there] Hi there folks, looking for some help here. I would like to consolidate and improve DC supply to my "head-end" comprising fiber modem (Inteno XG6846), music server (sonicTransporter i5 Gen 1) and NAS (Qnap TS-i410x) currently running off three wallwarts. So I am looking for an LPS with 3 rails capable of running off 230V and supplying 12V at 1A, 4A and 8A respectively. The sonicTransporter can live off anything from 12-19V (4A) and the Qnap 9-36V (8A) if that helps. I zeroed in on the HDPlex 300W which seemed to fit the bill perfectly. Unfortunately it emits a quite high volume mechanical hum and Larry at HDPlex seems insistent that sending me a replacement will not help so I am returning it. Larry has offered me a very generous settlement on the noisy HDPlex 300 to save me returning it so I am more than happy with the service I have received from HDPlex. However I need to find an alternative product that meets these requirements (must be min 3 rail and be able to supply the above 4 units, silently!), available in EU and preferably in the sub-€1k price segment and definitely sub-€2k. The closest I have found so far is the Keces P14. Surely, there must be loads I am missing?? Grateful for any clues for the clueless!

@Superdad is there a pre-order or first-to-know list for the JS-4?

Hi @Miska, Recently stumbled over these threads about GPU acceleration but I have not found any explanation of how the benefit is actually derived. To my simple understanding (EE degree from 1987!) DSP is an essentially sequential computation that doesn't really lend itself to the parallel processing strengths of a GPU. But then CUDA Programming hadn't been invented then and I would imagine the state of the art in DSP algorithms has probably advanced a bit in that time as well. Please could you provide a high level explanation of how the GPU acceleration mechanism works (or link if you've already provided one, sorry I didn't find it), I'm really curious! Many thanks!

Received my EtherRegen today (Sweden) upon returning from a business trip. Many thanks @Superdad for great communication and on-time delivery of a well packaged and nicely finished product. Now for the fun part! Forza UpTone!

Maybe just mount the part itself upside down??

You couldn't just mount this part on the underside of these few boards?

Yes, seems the Reactors can be paired through the app. Assumed they were the same as the full size Phantoms which require a Dialog. Seems the Reactors also have a combined analog/optical input (one that accepts a 3.5mm jack and a mini-Toslink) making them more flexible input-wise as well. Apologies for misleading info, assume makes an 'ass' you of 'u' and 'me¨..

Hi Kas, Let me try to answer your questions (remember, I am not an "expert", just a happy Phantom owner): - Phantoms only have digital inputs so you wouldn't connect them to a DAC but to whatever it is that feeds your DAC (streaming box, CD transport etc.) - Used in stereo you don't connect the source to the speakers themselves but to a Dialog box which synchronises the stereo pair (or more if you want). Dialog has Ethernet, and Toslink "physical" inputs as well as WiFi and PLC "Virtual" inputs. So for a CD transport Toslink would be your only option. Dialog supports stereo over all of these inputs. - I use mine in the dining room where we sit and eat for background music. I wouldn't describe it as an "audiophile setting", I suspect they would need to be further out into the room to sound their best. It is quite a large room (open plan with the kitchen) and the phantoms fill it with ease. Typically I am sat about 2m from the speakers or standing cooking about 5m away. Haven't tried them for near field listening, the full size Phantoms I have would be way too big to fit on my desk. I would imagine the Reactors might work well as desktop speakers although that is just speculation on my side.

Fascinating stuff @austinpop! I have yet to audition the Abyss myself, but have to say that the "medieval torture device" aesthetic does give me pause for thought (although I do think the ceramic coating somehow improves the appearance slightly over the anodized). The Empyrean otoh gets full marks from me on aesthetics (and build quality and comfort and packaging and..) not just on sound quality. In fact reinforcement of these brand values extends beyond the product itself to the broader "customer journey" and their website also exhibits a design aesthetic and a level of polish that really tick my boxes. I find that kind of "Apple-like" thoroughness very impressive, especially from a small company like Meze Audio. Kudos Antonio Meze! Anyway, an informative (and entertaining) read as always, many thanks for sharing these findings.

Haha, misread the date in your post, I now see it is over a year old. Sorry. Hope things worked out for you. Regards.

Hi bobbmd, Not really a fair comparison imo. The Phantoms are active and include built in DAC (Toslink or network inputs) and amplification, even an Airplay renderer, while the Legacy monitors are passive so you need to add the cost of those components in for an apples-to-apples. I own a pair of Gold Phantoms for several years and have been very pleased with them. They are surprisingly uncoloured, image well, have a good extended frequency response (give real deep bass, not a bloated upper bass that many people confuse with deep bass) and have huge dynamic headroom. The software (Spark) works but is not great imo, however coupled with Roon (which can feed them via AirPlay) this makes a great easy-to-use file- or streaming-based system. One word of caution though, I have found that you need to have a wired connection between the Dialog and your network switch to get the best experience, both WifI and PLC have proven somewhat unreliable in my apartment. I have only heard the Legacies once, at someone's house, and wasn't too impressed. To me the system sounded a bit bright, lacked bass extension and was not especially accurate (I didn't like the way it portrayed instrumental timbres), also the imaging was poor with no stage depth whatsoever iirc. I should stress that this was one listening session in an unfamiliar system and any of these observations could be down to the source, the amp or the room setup (on a bookshelf, far from ideal) and so not necessarily the speakers that were to blame. The owner loved them though, ymmv. Based on my experience I would say the Phantoms are definitely worth a listen, and as an active proposition with the functionality they offer I think they represent pretty good value. Imo it would be hard to better them with separates at the price. Good luck!

Cause or effect? You choose.

Four critical components in my main listening chain are new or have received major upgrades this year. I have never enjoyed better sound, neither has listening been more convenient nor my computer audio infrastructure more stable. That's progress! 1. Roon 1.3 with huge improvements to playlists and tagging, better library management, DSP, composers/compositions etc. The best just got very much better. 2. Sonore microRendu. 2.5 Firmware and clock upgrade. Ditto above. A "class A" digital transport for $640. Outstanding! 3. Uptone LPS-1 (with a special award (sainthood?) to John Swenson please!) 4. Devialet Expert Core Infinity upgrade. Bought a D-Premier nearly 5 years ago and in pretty much the fastest-developing area of audio technology it is still fully supported and being regularly enhanced with hardware and software upgrades. For all the whingeing I see on the Devialet boards I challenge anyone to point to a high-end audio brand with this level of commitment to upgradability. Nominated for this as much for relentlessly pushing the ball upfield on sound quality.

I'll certainly be happy to test when I have the time, which I didn't unfortunately have when I quickly hooked everything up yesterday. Just wondered if anyone was a step ahead of me.
