You mean Triad? Pretty well regarded for their speakers. Never saw comments about their branded electronics. I don't see pricing for their sub amps so hard to determine value but I imagine they work fine, altho for a sub amp I would prefer to see ratings for 2 ohm, but I just see a 4 ohm rating and a 3 ohm minimum impedance spec so might limit subs/wiring....what subs do you need the amps for?
ps DigitalDawn is a Triad dealer, maybe she can advise
