Anyone tried using Oyaide R 1 with Ribbon speakers

Rja:
I should have mentioned that I had FIM 880s in my system prior to the R1s. While I like the FIM, it seems a bit "soft" to my ears, especially in the lower treble. Triangles on nearly every recording I played were less clear, and the strike of metal on metal pretty diminished. The Oyaide returned the lower treble informationn to audibility.

I had 4 R1s in my system and replaced 2 with Fim880(G)s. For me it provided a nice balance.
Obviously, these things differ for each application and personal taste. Whatever works!

Interesting, Rja.
I installed a Teslaplex into the system, and, while others found it immediately involving, I found it a bit hazy and it unquestionably diminshed the timing of cuts in the Mercury Living Presence CD The Nutcracker Suite (the original, not the one Mercury re-released as a CD/SACD version [and a poorer version at that]. However, I wrote to Teslaplex' champion on this site,and he indicated that it took weeks to break in.
Perhaps the combination works well in your system, but the lower treble in the FIMs is definitely less present than either the PS Audio Power Ports and definitely less clear than the R1s. I had noticed this, but attributed it to other things in the system. However, balance is everything.
