What headphones do you prefer with the ECBA? I am currently using LCD2.1's with LCD3 pads and a Toxic Silver Widow cable.  I like the sound but do find the lower mids to be a little thick and soundstage a bit narrow (Royal Princess 300b's and TS mouse ear 6SN7).  I am considering the move up to the LCD3's but am afraid of losing too much bass.  Is there another headphone that works particularly well with the ECBA?  I have a low frequency loss so I need something with...
I tried various iso devices I had laying around - Ingress Audio roller bearings, DH ceramic cones, Herbies cup and ball combo and Herbies Tenderfeet.  The stock rubber over steel cones sounded better than all of them.  I had tried the same thing with the Lampi and found the DH cones to work better than stock but the Sistrum platform was far better.
Has anyone tried a Sistrum platform under their ECBA ?  I had great success with this platform under my Lampizator.

Has anyone tried an ECC40 (with adapter) in the ECBA in place of the 6SN7 ?
Sorry I can't answer with comparable experience but my PWD Mk2 outputs 2.8v and provides plenty of headroom to my LCD2's. The amp is stunning.
