    Looking for reviews of DC X63

    Thanks for that. I have checked out everything I could find online, but it looks like the last stock has been sold. So, I will stick with my ESL's that all of a sudden sound better ...after some more tweaks. Although they aren't in the race with my Pink Floyd LP's which I enjoyed so much with DC-XGen 4 and OTL valve amp a while back. Cheers, Rob
  2. Hi. I am a past DC X Gen 4 kit customer and have recently moved over to DIY hybrid ER Audio mini ESL's which give me great pleasure. My DC Xs served me well for about 4 years but are now with another happy owner. I have been trying to find some serious user reviews of the DC X63s but can't find any. Do you know where I can find some? There are a lot of DC X reviews around. Thanks, Cheers, Rob
  3. The original DC-X Gen 4 had heaps of reviews but I haven't found any meaningful reviews of the DC-X63 from owners. It seems a bit of a mystery as they are also on a runout sale. Are there any users out there who have had a serious listen to the VAF DC-X63? Thanks. Cheers, Rob

    Esl hybrid speaker

    Your spectrogram reminds me of a problem I had with my 505 ESL Mini Panels where the Satori 6.5 inch mid/woofers were overpowering the ESL panels. It was necessary to attenuate the Satoris by about 10 dB to retain a retain a decent balance between bass and the magic of ESLs. My readings were made from listening position with both speakers facing forward. Re the 10k dip. I get a similar dip with panels facing straight ahead but it improves with panels angled directly at microphone. For some reason, I prefer the ESL sound with panels facing forward.
  5. KEF LSX I have hunted high and low but couldn’t find any LSX reviews or opinions from actual customers so I thought this might encourage some others to contribute. My reference speakers are hybrid 505 mini ESL panels driven by Hypex nCore OEM amps and KEF LS50’s driven by a Holton amp. I paid under $1700 delivered for my LSX set. Firstly, these gorgeous little speakers have their own sound, they are not neutral but they are very musical and have enormous mid bass detail. Whereas the LS50’s were super clean and the ESL’s can’t really be compared because they don't seem to have a 'sound'. I didn't buy these for myself, but so the whole family could listen to their own selections without having to figure out how to use my gear. Setup is simple. There are only a few lines of instructions in the single sheet user manual explaining how to 'Plug them in to a power point and switch them on'. Once set up, I was able to use my Samsung phone with a pair of free KEF apps.an iPad and MacBook pro with AirPlay to control the speakers playing Spotify. Other sources can be selected such as my Aries Mini server where I could select all my audio files. Unfortunately, they just display as an alphabetically sorted list, but they do sound excellent. With Airplay, I could choose Spotify Connect or Spotify via Airplay and Aries Mini streamer. Streaming via Airplay sounds much cleaner than Spotify Connect which sounds a bit doofy and ordinary. There is also a substantial delay between tracks with Spotify Connect so I assume the servers are different. The speakers can connect to each other by Bluetooth which supports 48kHz/24bit or a supplied network cable connection that supports 96kHz/24bit transmission. It also supports source files up to 192kHz/24bit according to specs. I assume via TOSLINK. SOURCES SUPPORTED AirPlay 2 Spotify Connect Tidal Music (via KEF Stream app) Bluetooth 4.2 with Qualcomm aptX codec Optical input (TOSLINK) AUX input plus Subwoofer output HOW DO THEY SOUND To my ears, the sound is far removed from being audiophile quality but listening experience is exciting and enjoyable. Bass and upper bass were the BIG surprise because of the weight and detail which seemed out of proportion to these tiny boxes. Victor Wooten on electric bass is incredibly detailed, weighty and dynamic. Piano and stringed instruments sound accurate. Treble and mids aren't as harsh as I sometimes heard on the LS50's. Voices are so pure that minute vocal inflections are conveyed with a human emotion that is often lost. To summarise, KEF LSX speakers are exciting, musical, emotional and non fatiguing. Despite my bias towards my own system, and a disappointing start I really enjoy listening to them now. DISAPPOINTMENT When I listened in my main room, which is long, lively and has a tile floor, they sounded pretty grotty. Sounds seemed to just bounce around and the magic was gone. It was just a cacophony ! I think the room is just too large and too lively for such small speakers. The control apps have some EQ controls so speaker stands/cabinet, room brightness, edge distance and rear wall distance can be set to suit your own conditions. Bass and treble can also be adjusted. After customising the settings to suit my room, I could detect NO improvement whatsoever and I started to think I had made a big mistake. REDEMPTION...phew! We have a thickly carpeted spare bedroom that isn't used, so I placed the LSXs on some stands and powered up. There was a big improvement, but the sound was still out of whack. It sounded boomy and voices were recessed. More adjustments to the settings. Still no change. Now what? Brainwave! Reset speakers to factory settings with the app. I powered up and blast of glorious music hit me but it was too bass heavy, so I reduced the level until it was comfortable and got stuck into some of my test tracks. It seems to me, I may have fallen into the old trap of pushing the levels too high because these little miracles don't seem to distort at high levels. Comfortable listening levels, in a quiet, average room really let these LSX speakers shine and allowed me to experience some of my favourite tracks with a whole new level of enjoyment. The music and performance became more important than the sound for a change. SHOULD YOU BUY A SET? Most of the forum users are serious about audio and these speakers can't really be called 'audiophile' quality but they could introduce many enthusiasts to a new enjoyment listening to musical performances instead of listening to sound. NOTE: I don't know if the EQ control even works on my speakers but the factory setting sounds great when stands are used.

  7. I would just contact Chris as he has a number of customers all with different systems and he tests them on a couple of different rigs. The only time I had a problem with insufficient output was when I tried to use a lowish output cartridge with a phone preamp. Level was ok but I would have liked to have more gain instead have being almost full on.

    DIY Interconnects

    Bunnings keep a great flexible cloth tape that sticks like crazy, is thin and available in a couple of colours. I have used it on ICs and book spines. I must grab some more.
  9. A great buy! I have just finalised my hybrid build with 7 inch Satori mid/woofers. The panels are virtually plug and play so you can experience music as it was recorded with ESL sound in a very short time but they do sound much bigger with a mid.woofer.
  10. This is tricky review because it is actually a product but it is a product for DIYers. The newest 2019 StereoCoffee has reached the point where it has opened up the sound of my system with separation, life like reproduction of voices and instruments, venue ambience, dynamics and instrument/voice separation to a point that I didn’t think possible… simply, it sound’s pretty good! Over the past 18 months I, plus a few others have had the opportunity to audition most of the SC upgrades during that time and a/b test them directly with the previous version. I'm other customers will agree that the improvements are NOT in their imagination as some seem to suggest. The first version I tried had 3 boards and appeared to be a work in progress because of all the upgrades I tested over 18 months. The latest version only had two boards which are much simpler to connect. The brand new custom made boards are all hand wired to order by Chris and it takes almost a full day to solder, calibrate and test the boards. I reckon $250 is a bargain. The original boards had what I thought exemplary performance but Chris kept producing upgrades, all of which improved performance noticeably and in the last 3 cases, dramatically. I’m not capable of putting the experience into words, but a couple of knowledgable people have said. “If I listened in a dark room, I could believe their were ghostly voices around me.” Another was impressed by the "giant sound stage which envelopes the whole room with instruments". Based on my experiences, listening to high end gear at audio club meets, I thought the performance of StereoCoffee had reached a point where it brought my modest system a level which sounded just as good to me or even better in my own listening space. I didn’t think it could be improved. But no! I was wrong (again). My expectations were way too low which has been proven to me with the release of the latest and (perhaps) final board. Some how, this new power/control board is able to dig so much deeper into my music than I have ever heard to the point where my logic tells me this is not possible. In photographic terms it is like enlarging a super high resolution image that remains super sharp and shows even more detail as the size increases. In other words there is now audible detail within detail without resorting to digital enhancement. The purity of sound and absence of any audible distortion is very noticeable on my DIY hybrid ESL Mini Panels and Hypex nCore amp. There have been several USA nameless vocal detractors and one Aussie on DIY Audio Forum who have joined forces deliberately trying to discredit and humiliate Chris. It has recently been closed by DIY Forum Moderator. These unidentified ‘qualified’ engineers who have never seen or heard a StereoCoffee are calling performance improvements in the new one ‘snake oil’ and accusing Chris of ’ripping off customers’. All they have proven to me is that Chris has achieved something they are incapable of understanding through lack of research into how the performance of LDR’s change under various operating conditions. and StereoCoffee customers are reaping the benefits. Electronic development is changing fast and any LDR preamp manufacturer who claims performance of the original design can’t be improved or can't see the effect new D Class amps will have on the audio industry, must have their head buried in the sand. DISCLAIMER: I don't work for Chris, I am a happy customer who keeps getting happier. Hammond enclosure with waxed Mango front panel held in place by pot and switch to hide panel bolts Late 2018/2019 kit comes with two boards and newly designed power/control board can be powered by 12v AC or 15-18v DC wall packs. Small board at front is to isolate LED indicator from the main power supply.
  11. If it's any help, ER Audio in Perth supply replacement membranes for most ESL speakers. http://eraudio.com.au/ESL_Repair_Kits/esl_repair_kits.html
  12. Thanks. I have PM'd Ivan and will give him the costs for separates and freight.

  14. My apologies. You are probably correct. I didn't think about the possibility because I was asked some questions relating to a DIY item I reviewed previously , without noticing which forum it was on. Cheers, Rob
  15. Hi. The Hypex I have is an OEM version and is only available to manufacturers. I was able to get it because I am researching it's suitability for a manufacturer. Hypex did have an DIY version. Try https://www.diyclassd.com
