  1. I have to say I looked at buying this option when buying the LPS but really the increase in sound quality is marginal compared to the LPS. I've played around with changing wires and soldering directly to power supplies and it is an improvement but changing to LPS was an excellent improvement. Both sound and picture. My old Optoma HD21 picture never looked better. At $150 US its very expensive for what it is. In fact you could make it yourself if you had a mind and tools. Parts can be purchased separately. Robert
  2. Check previous page 34 for comments on Lush 2 settings.
  3. Well I own an Intona isolator MKI and in the end I removed it for good. It does have a cleanup effect but not without taking something away from the music. I would leave it out and get used to the Lush2 which has three settings you should try. Certainly get used to default setting before trying others. In the light of the HugoTT2 this already has a well designed isolated USB input negating the need for the Intona. In my view Intona fills a need with Dac's that don't have isolated USB inputs and these would be older Dacs by definition.
  4. Ralf have you contacted Oppo support? I've found them very good. Also try resetting machine to default settings. You will then have to reset all your settings for video and audio in the menus. If this doesn't work then you may have a fault somewhere. Robert
  5. I certainly get a better sound using digital audio files through Xxhighend output to 205 Dac by USB than CD, SACD, and PCM discs. The only discs I play regularly are DVD/Blueray live music concerts. But I've found digital music files much better than CD's ever since I entered the computer audio world. At the time I had a dedicated Meridian 200 transport upgraded, into a Benchmark DAC1 with Nordost digital connect. I was in a state of shock when this sound was beaten by a laptop with Foobar into M2 Tech Hiface DAC24/192 through a Benchmark DAC1 playing ripped 16/44 wave files from my CD's.
  6. I considered 3 devices Coris from Eu($400US), Oppomod from Korea($360US) and Chinese made LPS($200US). I chose the Chinese on price and it certainly looked well engineered. No doubt it could be better as all devices can be. It arrived well packaged and was easily fitted into 205. My only reservation is the onboard plug connectors were not as the original but plugs did fit them and seemed very secure. Firing up all worked perfectly. Audio was immediately noticable as smoother less sharp(digital) sounding. Noise floor reduced. But the picture gosh more depth in colours, sharper image. All I can say is for the money its easily justified for the improvements and Linear Power supplies are well worth trying. My Oppo 205 is 230volt with a Nordost Heimdall II power cord feeding it. By all accounts from other web sites the Coris is better sounding but was double the price with higher freight cost. As you would expect. Now I'm looking at my computer's LPS possibilities. 205 LPS.docx
  7. As a direct result of this topic I have changed the Switch mode power supply for a Linear one and boy does this make a large difference to sound and picture. I still have the original 205 Linear power supply in place as well. I would suggest anyone using a Sonica or Oppo video players should investigate this upgrade. I don't use the analogue multi channel board so left this out. Robert
  8. Happy New Year and I've had the time to retry "Tanf" again after listening for a month on Peters default. It was easy to pick and back to default within 20 mins. Not sure whether I needed to leave it set for longer but much prefer what I think is a better balanced sound with default.
  9. Go into Device setup menu of the Setup menu Check your Auto Power Off is off to disable it. Turn Sleep Timer Off which is default at Off. I leave my Oppo on all the time never had a problem with shutting down or sleeping. Its worth going through the setup manual and going through all the Oppos menus to check settings. It does take time but worth it especially to optimise playback settings. The DAC is superb and my main DAC after selling the Benchmark DAC2. There are better DACs but cost much more. DAC's have not advanced much in the last year or so I believe. For dedicated audio use I also disconnect any connection to the internet, wireless in particular caused interference issues with my speakers. I only use the Oppo in stereo so have also disconnected the power supply feed to the 7.1 Analog board under the hood. This is a worthwhile audio improvement. It only involves pulling the plug from the power supply board, so easily replaced. Only do this if you know what you are doing otherwise get a Techman. Does void warranty but is harmless to the machine if less than 2 years old from purchase. Warranty on mine is long gone. The power supply in the Oppo 205 is better than the Sonica. The UDP-205 has two separate power supplies, digital(switch mode) and analog audio circuitry is powered by a toroidal power transformer(not sure how linear this is). The only issues I have had are HDMI connection ones with video sources from TV tuner and computer when switching from one to another causes audio sync problems or screen goes purple. I think this is largely an HDMI problem but remains unsolved. It is an excellent Blue ray/DVD player. Bloody shame they stopped making them. Robert
  10. Yes I'm retrying default config then will try Tanf again. I do concur with this statement though from tipunch over this last weekend I was surprised how much bass I still have after changing from JS cubed.
  11. Have to say I’m back at shipped config. I agree with Peter, Tanf too trebly and the other JSG cubed is to much bass.
  12. Hi I did not compare to same recording downconverted to 16/44. I compared to remastered 2009 CD 16/44. Generally I don't compare to downconverted anything, can't see the point. I know this recording particularly well it was the first vinyl album I bought when it was first released 1969. Crazy that I have now bought 5 versions of this pressing including blueray 24/96. I didn't need to directly compare it to the old CD's I could tell immediately it was better. Same went for Led Zeppelin remaster releases 2014 by Jimmy Page. The 24/96 versions were the best I've ever heard and I owned the lot from vinyl, cassette and CD(plus remasters). I would go as far to say these later versions easily bettered my best vinyl setup using my computer audio playback system hearing more detail and music, obviously on the original recording but masked by humans and technology!!!!
  13. I've only felt new recordings in 24bit and beyond really show the improvement over 16/44. I have a large number of so called remastered 24 bit and these really are a mixed bag some better and some not. Giles Martin's Abbey road is a marked improvement over the vinyl, cd and remastered CD. This alone means its well worthwhile pushing for 24 bit recordings. I do notice more and more new recordings are now being done at least with 24/48 if not 96. Having participated in Mark's last blind test where it was obvious many could not tell the difference between music files. This is doomed to be repeated and is only happening within a small community of HiFi followers. Even if 16/44 was realised to its full potential for all the right reasons 24 is a worthwhile quest and improvement in my view. Robert
  14. Never found sorbothane to be an advantage under any hi-fi component. Its somewhat an insulator damper and certainly not rigid tending to keep any vibrations within component and dulling the sound. I cut a bamboo board into pieces 20 x 30 x 18mm thick and use these between components and shelf(mostly 3 to a component). I still use blu-tac under speaker to speaker stand(laminated Maple) which is spiked to floor(wooden). I subscribe to theory: better to remove any vibration to earth with different materials to break up resonances as quick as possible. I've made footers from brass, copper, aluminium and stainless steel(spikes, cones cylinders) all impart a different sound that tends to be brighter. Hence my moving back to wood which is more forgiving and seems more balanced.
  15. A major problem is what the listening room is made out of. This in turn influences devices supporting components. In reality its a minefield and one can only get a good compromise by trial and error. Let alone airborne and floor vibrations which is where good component construction comes in ie: circuit boards chassis and cases. Personally I lean towards wood in various configurations. I use to manufacture all steel welded rigid frames with iron sand filled columns spiked to the floor and shelves spiked to frames. My last one of these had black granite 30mm shelves. Replacing these with Ikea butcher blocks did change the sound and I much preferred it. Nowadays I run a laminated American Oak rack with bamboo footers under components. I run on the theory that a lot of critical music instruments are in fact made of wood and this is what gives their particular sound trait.
