Are or do the jupiter caps have a place in the tube  output stage of the zcd 200i.????

I use Tom Danley (former NASA engineer) designed Unity Horns (four mid-range drivers feeding into the throat of the horn) with B&C compression driver for the highs and Lambda TD15M 15" woofers to cover 70-300hz, and a separate WO32 sub using a pair of Lambda 8" woofers and a danish 100W plate amp.  

Having used lots of speakers from Acoustats to hand-tuned 3-way beasts and even tiny monitors of stands, these Unity speakers are the most capable in terms of effortless realism.  They are pretty complex compared with crossoverless single driver speakers, but I have yet to hear anything which are better to my ears.  Horns without the horn sound.  

I'd like to get a nice DAC source with lots of output voltage to best drive my Blue Torii amp.

And eventually, a nice vinyl rig sure would be the ultimate ticket with MC step-up, preamp, turntable, etc. -- way big bucks to do it right, like about $5K minimum.

Still, I could likely tune about any speaker to sound decent with a good amp and CD player.  Just takes time and tweeking with your ears and intuition on what needs to be done.

sounds like you two have put in alot of time and money into your speakers . I too have put alot of time into this hobby /obsession.... from about the fall of 1974 til now always searching , but never finding audio truth . until 2 companies came along  Decware and common sense audio. where the not so effluent guy could  put together a true State of the art system for a song  . there are other companies that make life easier to bare also . I've put a ton of my money into this over the years never being able to afford the BEST!!! I'm forntunate to have taken this ZEN road to fine sound . I always knew there was something to this , but was brainwashed to the high end cliche' that corrupts us through the underground magazines and HIGH END stores that are in it for the big bucks. Theres my vent , without saying any bad words

I love the ERRs, to me they just present a more natural presentation of the music, more the way that you hear music in "the field" (or in your home if you are a musicians or have musicians making music in your home). That's really what has glued me to the ERR (and HR-1 Omni)--that "out of the box" sound.

I used their predecessors (RL-1 an RL-2) in a small rook with a Select amp. Great sound, but. . . I felt there was little headroom, and wanted more power. Eventually I moved them to a larger room and used a pair of Decware SE34 Monoblocks and an SE34I.2 but in the larger room still had that same sense of wanting more reserve, wanting that ease of sound. I moved to the ERRs and to a Torii Mk II and then Torii Mk III and there's more juice and power than I would ever need, and I feel that is a great match, a great partnership between amp and speakers. The ERR are a bit more efficient than the RL2s were, but I'm not sure that the SuperZen would be quite enough of a brute to be an ideal partner for them if not in a small room.
