@denon1, I’ll run through your questions one by one..
"How reliable the Vitus RI-101?" - I guess the first thing to say is, Vitus Audio are a luxury brand like AP or Hublot, not a mass market brand. Their new factory in Denmark is SOTA They are using machinery which is VERY expensive. This article will give you some idea - https://www.monoandstereo.com/2016/12/new-state-of-art-machines-in-vitus.html
If you want to learn about the philosophy of the Designer, Hans Ole Vitus, there is an informative series of short videos here - http://www.bestofhighend.com/hans-ole-vitus-part-1/
And unlike some other high end manufacturers, they design and built the majority of their chassis parts (incl: boards) in-house. They are all about attention to detail, which you see from their well made and immaculately shipped boxes through to the signed QA sheet inside the box & well written manual on cd.
"Is it on the same level of luxman, accuphase, gryphon?" - I recently did an a-b shootout between Luxman, Accuphase & Pass .8 series separates. Build quality on the Japenese amps was excellent, and fyi in that shootout I preferred the sound of the Accuphase A-70/C-2850 combo. But the Vitus RI-101 and SIA-025mk2 are playing on a higher level imho. As for Gryphon, I would rather not comment on them in the forums. Will pm you.
"I don’t think we have service in US from Vitus, this is the only thing that stops me from considering new vitus integrated" - Vitus definitely have Distribution in the US. Bob from Rhapsody Audio in NYC is one of your main Dealers, and is also an authorized Service Centre for Vitus. From memory, there are atleast four or five Dealers in the US. Maybe drop Bob a line and ask?
"I currently have luxman 509x driving canton reference 3k speakers. I like the sound but feel that on a higher volume levels it should be more relaxed, and instead it just gets loud with some harshness that I don’t hear at lower levels. To me its a sign that I need more power to drive my speakers maintaining the same level of refinement that luxman provides" - It does sound like the Lux is starting to run out of puff. It has a damping factor of 370 which is not very high compared to even Accuphase. I recently reviewed the Vitus RI-101 fyi before changing my member name & saying sayanara, (or "proshchay" in Russian) to that forum - https://www.stereonet.co.nz/forums/topic/16208-my-impressions-of-the-vitus-ri-101-integrated/
