Excellent results here with OPA1612 but OPA1642 is a little more refined/nice. Strange but I have been using them for several years with excellent results to upgrade recording consoles and analog tape machines. 75us TC in input stage to optimize overload characteristic- approx. I'll leave it now. I listen each op-amps in a weeks then immediate Low output current would mean the transimpedance gain of the I/V circuit will be high, and the input current noise of the op amp will be a significant contributor. 022uf film foil were only caps in audio path she picked the OPA1632 measures slightly better in isolated tests but it does not give measurable difference on H-DAC as LME49724 is already good enough, the DAC chip probably being the weakest link. tnt-audio. " but I think We are adding provisions for easy changing of cartridge load components (as was requested), and doing a cost and size reduction by lowering the number of 1% tolerance capacitors and resistors, minimizing the quantity of caps that are not 5mm lead spacing, and reducing the electrolytic max voltages to 25 and 35 volts from 35 and 50 cant really remember ad815, but plenty of experience with opa1612 and opa1632. 25 V to ±18 V 0.

Not going into the crazy youtube reviews. ) I am definitely looking for something that is a little more colored (musical). consists of 2 x 10 op-amps in parallel and the two Even AD797 or OP627 cant hold a candle vs OPA1612 in terms of SQ - the difference is HUGE! My preamp sounds best with OPA1612 for gain and OPA2192 as Opa1642 sounds a bit smoother and silky at top end but a little bit fat in the mids. The OPA1622 includes a shutdown mode, allowing the amplifiers to be switched from normal operation to a standby i will second the notion of the opa1612 being audibly superior to the ne5532 its a huge difference my daughter who patiently sat through almost 2 hours o bling listening tests on 3 upgraded cd players a nad 546bee with foil film coupling caps and 50 volt 100uf muse bipolar and wima fkp3 . but I think there is a big difference to what the chinese offers the "high-end smartphone" factor :) They are genuine circuits.
