The sound out of jplay 6 is astonishing

I actually think the problem is my DAC being sensitive to input jitter, so if your DAC handle crappy input better, then jplay would not be needed.

I'll be getting a different DAC in a month time so I will find out...

Also going to be trying out AES vs the USB that I'm using right now.

The magic bullet seems to be an optimized machine like CAPS running Windows Server 2012 with latest beta AO, Jplay 6 and throw in the latest Fidelizer as well. My friend just recently updated and those who have heard his system claims it's the best digital sound they have heard. I run a dual server setup and am quite happy with the sound I am getting now so I am holding off the updates for a bit.

Maybe there is something dramatically different in version 6 vs 5, or in AO version 1.30 vs 1.26 that I have. But in my experience and with a singlePC very similar to AudioPhil's (and CAPS, for that matter), it didn't make a huge difference. Maybe it's the DAC, like Coli said. Or maybe my speakers aren't resolving enough (B&W 804S).

FWIW, room correction at the PC through Acourate has made a significantly bigger improvement in my system than JPlay. Yet I want JPlay to work for me so I will probably give it another go down the road.

Alright, AES is good stuff, turning the buffer size to min was key. No longer needing jplay 6 with aes.

I have not tried a DAC that wouldn't benefit from JPLAY yet. Currently using APL DSD-S via USB. Amazing DAC, best I've tried so far, but still sounding better with JPLAY and all hardware tricks in my audiopc :)

Marcin, as you are in Warsaw, why not arrange a demo with Lukasz and see how JPlay 6 meshes with the Lampi DHT tube Dacs? I would be interested to hear your impressions.
