  1. ultraRendu or sMS-200Ultra?

    Component interaction in different setups and different listener sensibilities come into play. In the end one has to listen with their own ears and using their own audio system. If you cannot do this, with this level of performance, toss a coin and hope for the best.

  3. I moved the ISO Regen to another setup that uses the mR and a different DAC (NAIM DAC-V1). There are no switching issues (mentioned above) in this setup, and IR benefits are more apparent. I moved the LPS-1 to the IR. PC/PPA V2 USB (LPS powered)>Anker USB/Ethernet>mR (LPS powered)>USPCB>IR (LPS-1 powered)>USPCB>DAC This setup has improved the perceived bass response (detail & extension). It is also apparent that there is much less digital edge/hardness/glare remaining if any. Good & thanks to Uptone/Sonore! ATB.
  4. Hi Cornan, Frojo Gnd wire does not fix this - I found that just plug-unplug USB chord also works. I will be doing this in the meantime. Thank you both for your thoughts and input.
  5. Hi Cornan, Thank you for the suggestion-did it but it does not help this situation. The controller reports 'unknown usb device (device descriptor request failed)' until I cycle the IR power B.
  6. The bold text above should have read 'until I cycle power to the ISO Regen'. On/off of the DAC does not change anything.
  7. I have been using the USB Regen with a Teac UD-501. I have a laptop plugged into the Regen which is powered by a TP 7/2. I have two other source components I use plugged into the SPDIF inputs, so I have to switch inputs every now and then. All worked well with the Regen. I replaced it with the ISO Regen (ISO engaged) . It works fine however when I switch to another input and return to USB, the DAC does NOT go into 'USB ready' mode, just displays USB. It will not 'lock' (or handshake?) with the ISO Regen until I cycle power to either of them. Not a deal breaker, only a royal PITA. This did not happen with the Regen. Is there something that can be done -firmware upgrade or the like? Any help is most appreciated.
  8. I have tried (LPS-1 > mR) 1. the Cardas Litz 15.5 awg copper wire (as a twisted pair). A smaller gage (21.5) can be used for star quad, but I did not try this. available at: http://www.partsconnexion.com/wire_hookup_cardas.html and 2. the mil-w-16878 22 awg (silver plated copper strands/teflon insulation) in star quad . These come in spools (100ft Belden or Alpha Wire being the shortest). They are commonly used in aircraft/aerospace and at times can be found cheaper on ebay in left over form (hookup or cable form). e.g. http://ca.mouser.com/Wire-Cable/Hook-up-Wire/_/N-5ggs?P=1yzs67rZ1yxufheZ1z0juks&Keyword=alpha+wire&FS=True https://www.ebay.ca/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H0.Xmil-w-16878.TRS0&_nkw=mil-w-16878&_sacat=0 connectors - I used the Switchcraft 762 (762K for the locking one) http://ca.mouser.com/ProductDetail/Switchcraft/762/?qs=sGAEpiMZZMtnOp%2bbbqA00xVNfTC1Zp0MB0v2MPeNOaA%3d The mil-w-16878 in star quad edged the Cardas (twisted pair) in musical terms. I have no commercial affiliation to any of these products. (Also posted at Uptone sponsored DIY thread )

  10. Just a comment re: option 5 -bridged connection. I am using the PPA v2 USB card with the Anker Ethernet adapter into the mRendu with great success.
  11. You are welcome - glad you tried it and liked it! Amazing performance for silly money!
  12. Thank you to the OP for this tweak. I used an Anker USB to ethernet adapter plugged into the Paul Pang USB hub with a LPS. I assigned a static IP address to it and bridged it with the main network! That by-passed the TP-Link switch & MC110CS FMCs I had been using. The clarity of the soundscape is even better, the backdrop seemingly dead quiet! For some reason that I have not figured out, when I insert the FMC loop into this direct setup the stereo image deteriorates, the complete opposite of what I was used to! Dual core Win7 PC/J River MC 22/Paul Pang V2 USB (+LPS)>Anker USB/Ethernet>Tera Grand CAT-7 Ultra flat 1.5m>microRendu (+ LPS-1)>DIY USB cable>Naim DAC V1 I found the very affordable Tera Grand 'CAT-7 Ultra flat' with the braided outer jacket to be excellent in that position, among the few that I tried including the AQ Vodka! - but I understand there are cheap counterfeits out there (so -mind where you purchase from if interested).

    Great - thanks.
