The OPA2134 series are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. It's been in use for a long time (some time around 1954), and was 'tinkered' with by the IEC to tame the bottom end. That was the circuit where the OPA2134 sounded better. NO. Buy OPA2134PA - Texas Instruments - Operational Amplifier, 2 Amplifier, 8 MHz, 20 V/µs, ± 2. The original preamp shown on these project pages is basically a good design, but in the interests of improved quality and reduced 'frills' this new version will fill or exceed most quality comes largely from the use of good quality opamps, such as the Signetics NE5534 or Texas Instruments/ Burr Brown OPA2134.
And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher voltage noise of the opamp is negligible, like here. The 2134 in all three positions is also nice and pleasant, but missing a bit of realism.12/Item) FREE delivery Jul 28 - Aug 1. 모르겠네요. The reason why i want to use two opa627 is i cannot find an opa2134. So far, my favorite combo is the 2228 in the input (U1) and the 2134 in the output buffer (U3, U4).
