I currently use jot 1 with modi multibit. I can sell my jot1 and buy brand new thx 789 for a similar price without paying more or I can get jot 2 for 40 percent more money. my cans are DT1990, HD600, K712, SR325e, ath-w100 and mdr-1A and maybe get an M570 in the future. I will use XLR output for my 600s only and the rest of my cans will be run unbalanced. so SE performance is crucial for me. now what you suggest? is getting a 789 without paying more money a good upgrade over old jot1 or I better get the jot2 instead if upgrade is worth extra 40 percent money? imo jot1 really suffers from poor treble performance. kinda congested and busy in top end with mediocre at best separation. I want a little more effortless presentation a touch more space and of course less glare. I don't need preamp and obviously I'm gonna feed them via RCA. so any help would be appreciated. thanks in advance
