I had a PL Dialogue Premium , honestly, yes to be fair,, I really did not give it enough time to review,, all I know is that I prefered my Chinese Jadis Clone LS9 with 3 12AT7 stages of amplification, and with Mundorf EVO OIl Silver caps,,
The PL Dialogue seemed to *twist* the musical image into shapes i did not like.
Better word is *controted*,, = spasmatic,, Again, thats not being fair, becaaue only after 1 or 2 test songs,, that was quite enough,, I returned it to seller with a gratuitous $200 restock/hassle fee, and I paid shipping both ways.
Gotta be fair in this business.
I just posted my opinions ona Linestage shootout, Neither of which i actually heard in my life.
There i give my choice as to best Line stage on the market,,outshotting any LS under say,,,$15K
I might get one, only to prove my opinion,, as i am quite happy with my Jadis DPL modded by Richard Gray, (which i've yet to hear his mods, as my sperakers are being modded next 2 weeks).
I'm sure Richard corrected Jadis' 20 yr old design. By eliminaing the big loud mouth 12AX7 and installling the glorious delicate 12AU7, which i call ~The Emblisher tube~ vs the 12AX7 which I tag as ~~The Screamer tube~~.
The key to any superior design ina LS is the db level.
Cayin SC6 comes it at 15db.. I am sure both your choices above is near double that.
Unless you happen to like massive db levels,, then yeah skip the Cayin.
IMHO a LS should be passive as possible 15db is the mark,, over that you ~~might~~ have excessive gain issues,, Which is what Richard Gray hopefully corrected in his mods of the Jadis DPL,,I'm guess, will make a YT vid once speakers get new high tech xovers
issues.
