    Did anyone’s HoloAudio Control Panel driver break after installing the newest Windows updates?

    I removed the ISO REGEN from the setup and it’s still not working...

    I think I uninstalled the driver and then reinstalled.
    Running windows 10 v1709

    No Windows issue here with latest update. My chain is in the sig and I'm using the ASIO driver that supports 512 DSD in JRiver.

    Hey @bflat is see you have both the iGalvanic and iPurifier2. Have you tried both with the SU-1 and how much improvement (if any) did you hear with the iGalvanic?

    I ask because I'm still using an iPurifier2 and, based on the accolades I've read, the SU-1 seems TOTL for USB interfaces. I'd considered moving up to the iGalvanic but it's 3x the price.

    Along with the Matrix X-SPDIF 2 which is similar price and already has a DC input that you can plug an Uptone LPS-1 (or PS of your choice) into without any mods/kits required.
  6. Energy
    False call.
    It was the ISO REGEN that broke.

    When used in-between the SU-1, the SU-1 won’t detect. Well i’m kind of happy it happened. For awhile now I thought I’ve been hearing small pops but just told myself it was placebo.

    So what are you gonna do about it?
  8. Energy
    Return it to Uptone Audio and hopefully get another one that works. It’s hard to see my chain implementing another type of USB regenerator since I still need my computer for HQPlayer otherwise I would have gone the SOtM route like you.. :[

    That Tx-USBultra looks tempting. And the iGalvanic 3.0 from iFi. I was at the Capital Audio Fest yesterday, and iFi had a nice booth there.

    No I have not used the iPurifier with the Holo DAC. I only use the DAC with the SU-1 with I2S output. I got the iGalvanic since the USB data input of the SU-1 does not have galvanic isolation. iPurifier would be redundant with the SU-1 since it is a reclocker and noise reduction. I do feel the iGalvanic added a lower noise floor to the SU-1.

    any comparisons with the Gumby? especially the level 1.
    I know Level 3 will most likely be better in every way
  12. thyname
    Did you compare the iGalvanic with ISO Regen?
  13. bflat
    No I haven't. I'm sure the products are comparable. Both companies are well known for their noise cancelling technologies. I went with iFi because I have a lot of their products and found their technical support very responsive and thorough.

    What does the iGalvanic adds to the sonic experience of level 3? I am thinking of improving my chain but not sure if the addition worth the extra dollars.
  15. bflat
    I made a couple additions simultaneously - SU-1 DDR mod and the iGalvanic. I thought both lowered the noise floor further and created an overall better separation of instruments. The difference is more evident listening to my Utopias but not so much with my TH900.
