You are spot on, Normie. The ribbons especially seem to be the cream of the crop for timbre and tonality (at least they are for me). As for the filters, I'm going to try using HQPlayer with the filters and that should change things considerably. My franken-source has 52 cores, so I'll try pinning some to HQPlayer processing w/Mitch's filters. I many also try offloading HQPlayer to another machine all together as that would likely yield the best SQ.
I can't wait to hear this friggin amp lol.
100% correct. The tubes on the EF1000 are implemented at the input stage then bridged over to the SS at the output stage. Reminds me a bit of the I/O architecture on the WA33 with far less tube-y goodness, but with ridiculously more power. This thing drives moderately power-hungry speakers (FR30s, Dunlevy SC-IV's, etc.) with tremendous ease and control. WIth headphones, I can't listen to NewTopias above the second volume dot or they get way too loud. If I didn't have speakers and if drums didn't sound so d@mn good with the SRs, I might consider selling it, but I would almost certainly regret doing so in the long run. It reminds me of an uglier, overpriced, hotter running, yet equally versatile CFA3.
Oh yeah - they definitely need smooches. I'm going to try everything I can to use Mitch's filters with a cleaner DSP implementation. Roon's engine just isn't cutting it, which really isn't all that surprising.
This will definitely happen, it's a question of when. Apparently, my VM-1a will be arriving sooner than expected so I best get ready. I just reached out to the folks at Elrog for a tube set recommendation for the VM-1a. In my limited experience with tubes, 300Bs seem to yield some of the best possible SQ, but the cost is nutty.
Appreciate the tube recommendation btw.
