Front end is a Grimm Mu1 server/streamer feeding a Chord Dave through a Bibacord AES/EBU digital cable. The Dave goes to the Elekit integrated 300B amp through Cardas Clear Beyond RCAs. Emotionally involving. It's addictive.
There's an English Electric switch handling the ethernet, connected with a Muon Pro ethernet filter to the Grimm.
Relocated the GR-Research open baffle servo sub 4' behind my listening position. It totally disappears there with no room modes! Sounds like all the bass is coming from the soundstage.
Both the speakers and the amp are kits I built with a lot of help from my brother-in-law, a retired circuit board designer.
Room is irregular, including gable windows behind me, which certainly helps.
Speaker cables are all silver Gryphon Guideline cables from the '90's.
Nice! The NX-Oticas sound great with 300B SET amps. I have recently passed my pair to my son and replaced them with GR Line Forces. Nice idea moving the sub behind the listening position. The Line Forces cross over quite a bit higher, so that's not an option for me.
Is that acoustic dampening green tape on the carpet ;-). They look amazing. How long did the build take? I'm really tempted to attempt this build, at least the servo sub for starters. And why did you go with a single sub vs. left and right? Do you plan to add a second servo sub or is this sufficient for your tastes?
