I have my PSiK's for a little while now amped with the WA6, and I do like the sound…but I was wondering if the PS1K's would benefit more from a Hybrid amp like the Schiit Lyr. Have no intensions on letting the WA6 go, I love this amp, but am thinking that the current from the Lyr (or another Hybrid amp) would suite the PS1K's better for precision/speed.
Also does anyone use the Lyr (or other Hybrid) with the PS1K's, and feels a Hybrid is very good match for them? I was also interested in the Fosgate Signature Headphon Amp, I can pick up a demo model for a discount, but it would still be double the price of the Lyr, and I know the Lyr is highly regarded on Head-Fi. Also, I don't see many comments/recommendations, or people on Head-Fi that use the Fosgate amp, and also I'm not really into the bass boost surround sound/filter features, I pretty much like my things simple, so if anyone has any experience with this amp, I would also appreciate any comments about it. Keep in mind this is for the PS1K's only, not my other Grados.
Have you tried the Sophia Princess and 6EW7s with the PS1Ks? I like that combination quite a bit, though with a WA6-SE, not the WA6.
A lot of the tubes I like with LCD3s, particularly the USAF 596, don't work for me with the Grados. YMMV of course.
