Jul 4, 2009 · If I'm in the mood for that so called "burr-brown" slower lazier sound I prefer the OPA2228 but as with my comments about the AD8066 below you can't just drop that into any old circuit and get good results - the OPA2227 is a more drop in replacement but doesn't sound quite the same as the 2228. Tangent didn't mention AD826 and LT1364, which are my best choices. So, it is a different design and chip. ) He talked to me about OPA1611's versus OPA134's as well as the OPA1612's versus OPA2134's. 1-nV/√ Hz noise density with an ultralow distortion of 0. My main attraction to them is a higher ripple current in the AC to “ power” the board onward as the opa1612 only requires low quiescent current of 3. It's supposed to be a stright up replacement but it's about a third of the size. edit: looking closer at the pics, the I/V resistors are 390R (about half the datasheet values, which makes sense as they // the outputs). My first set of separate OpAmps, ushering my foray into the brave new world of OpAmmetryLoL Dry, crisp, analytical and non-intrusive (as compared to the bold NE5532) is what I would describe this opamp as. I personally like it in the right circuit and feel it adds clarity and imaging. - high levels of DC precision are generally not required by audio customers (audio equipment makers). Mar 17, 2019 · The OPA1641 would be slightly better. I did it mainly b/c I heard that there was better sound quality. How they perform for audio depends at least as much on the circuit they are mated with, as their own inherent qualities. IMHO the outcome was mostly decided by how the opamps responded to the RF coming out of the dac chip. New comments cannot be posted and votes cannot be cast. the best sounding is OPA1612 ,not for driving headphones -low output current drive ,3ma current consumption ---then opa2134 the best all around as preamplifier it can be used at high gain 6-10 times,very good sounding and Musical,good for biassing in class A. avgwfz hxxj zmjpb mqnrc drqk qbrrqmh cwxrio vhxkf vwuzeh oypqv
