I am a relatively new member of head-fi and have read through the entire Invicta thread as well as the entire Anedio D1 and D2 threads. I ended up purchasing a D2 DAC in mid February. I have been enjoying it, but it has fed my desire for even better sound!
I purchased the Audiophilio 1 USB to SPDIF converter, with the Pure Power option. It is a nice upgrade from the D2 by itself. I also plugged everything into a Power Wedge 116, which combined with a PS Audio Noise Harvester, quite dramatically cleaned up my system's sound (As a long time audiophile I was pleasantly surprised at the imp
I listen mainly through speakers (Opera Callas), sourced from a 2012 Mac Mini with a 960 GB SSD (no moving parts). I also listen to my Oppo BDP-83SE sometimes or a Magnum Dynalab Étude tuner. Since I got the D2, I have brought out an older pair of Sennheiser 580 headphones and really enjoyed those when its too late to turn up the stereo : )
Unfortunately, the D2 won't play any DSD files and I am going to convert my roughly 50 SACDs to files that I can put on the Mac Mini. So, I have been very interested in the Invicta....
On top of it all, they are just a few hours up the road from me!
Yesterday I called Resonessence with a question about using the Invicta with my AP1 with PP and received a call back from Martin. He suggested that I wait a few weeks as they are coming out with a new model and it might suit my needs even more than the standard Invicta.
They will be announcing the new model shortly, once all of the initial issues are taken care of. I believe that we will see it in mid May.
Sorry to go on so long, but I wanted to introduce myself as well as let you know about some exciting news!
