I've never considered return policies from overseas sellers as most efficient way to audition equipment. Between shipping, possible custom fees, time constraints, restocking fees, always sold my audition equipment.
No surprising someone finds 005 dac not for them, no dac is for everyone. 005, assuming one's systerm capable of exposing it's resolving capabilities would never be less than engaging, however, its not a flavored component. Some will perceive that as analytical, not soul stirring. There are many recipes available in getting to soul stirring systems, 005 may not be right ingredient for all recipes.
pt99 experience is the one criticism I presumed would arise at some point. The recurring thought I have is the person considering tube dac or R2R dac for their reported flavorings will be those most likely to not like 005.
Some want digital to sound like vinyl, a futile effort in my opinion. I do accept digital can be more or less forgiving, but analog, no. I have pretty nice analog setup, and grew up listening exclusively to analog so I think I have pretty good idea of what analog sounds like. For me, digital doesn't have the TIMING of analog, analog has a sense of relaxation, ease I've never heard from digital. Highly resolving dacs only accentuate this difference in systems not optimized for digital. The same dac that sounds analog like in one system may sound harsh, analytical in another. 005 requires every single aspect of system to be optimized for digital in order to show it's full capabilities. One shouldn't expect it to sound just like vinyl, for some thats no go, reason they don't care for any digital. As for sense of actual performers in room, this is reachable for digital, and 005 in particular. For me vinyl is romantic, warm and fuzzy feelings, 005 digital totally engaging, exciting, both satisfying in own way.
From my perspective, 005 is nearly last piece to put in already digital optimized system. Streaming needs to have top notch network, usb renderers, cabling, etc. home AC cleaned up, no grounds issue, room treatments, and of course sympathetic amp, pre, speakers, top notch transport for cds. If 005 purchased prior to full system optimization very likely one will be working on rest of system to obtain full capabilities of 005 or selling unit.
In this, I don't think 005 different from any highly resolving piece, it will show the warts. One has to pay steep cost to get both highest resolution and soulful presentation, all the t's must be crossed, i's dotted.
