I have 3 different systems and its buzzy and noisy in all three,
1.
Office Croft Micro 25/ Croft 7 Power amp Harbeth P3ESR (Nordost Purple Flare Speaker cables/ Kimber interconnects) DAC Arcam IrDAc2
2.
Living Room -Cary SLP98L (Primo NOS 6sn7 tubes)- Project Phono Box RS/Prima Luna Prolog 7 Mono Blocks, (Primo NOS tube Upgrades) all Nordost (Cables-Red Dawn Speaker and Blue heaven Interconnects) DAC Arcam Ir Dac
VPI Classic/Hana SL (Kimber Upgrade)
Primo Power cables/Kimber- X 3 CablePro Noisetrapper NANA power strips
I offer this info to show that the Loki is the company of decent gear,
it is basically, a dead quiet system with the blackest noise floor until I add the Loki.
It buzzes in every position I place it.
I have written twice to Schitt for comment and I requested information on a better quality power supply as I think the super cheap power supply's that ship with Schitt is in fact total Schitt. I have never received a reply.
I actually visited their store in Santa Clarita CA and was met by a rude young man who seemed bothered by my desire to ask questions about the gear on display.
I will try a 120v 16W power supply from a different supplier in the hope I can get this little thing to work.
I wish this company well and want them to succeed but their customer service for me is non-existent. I did wait for a while to comment on this thread, hoping for a reply to from Schitt to my latest email? no such luck.
PS, I had a friend borrow the Vidar power amp to drive his Quad ELS 57's and hated that combo. He said it was harsh. He did not spend much time with it. It may have sounded better if it had more time to break in?
PS
I have a Schitt SAGA preamp (primo NOS Kenrad 6sn7 tubes) that works just fine in my bedroom set up.
