See if you can find one of these https://reverb.com/item/35095711-creek-obh-12-passive-preamplifier-with-remote-control-in-excellent-condition. I used one back in the day with my Jolida JA502A and connected my OBH-8 phono stage and Sony XA20ES CD player through it and it was just the ticket. Does not alter your sound in any way and also allows remote source selection and it even has a tape loop. The one in the listing sold for about what they cost new.
Remote Volume Control for my Decware amp
I recently received a Decware Zen Triode integrated amp (after 3 year wait). The amp is exceptional and puts my Krell Duo 300 XD to shame. The only drawback is the manual volume control. I really enjoy cranking up certain songs and adjusting it down when volume is too loud. While I can run it through my Schiit Freya Plus that was paired with my Krell, i fear I’ll degrade the sound with more connectors and electronics In the signal path. Although the Freya plus has pass through mode, the Freya may not match the quality of the Decware. Is there a solution that will not degrade the purity of the signal path? Steve had recommended one if his devices, but it’s a waiting list item and i Can’t wait another 3…4…5 years.
