Even an AD797 is much cheaper and is regarded very highly. Introduction Design engineers face the challenge extracting the best possible performance from the least expensive. Technicznie wole OPA2134 ale mimo wad chyba jednak zostawilbym NE5532 gdyz wole to dociazenie. But do they? The chip companies don’t help the perception implying some of their op amps offer better sound. TL072 is a very high input impedance device > 10*4 Mohm to that of NE5532 which is in Kohm range! The noise spec too is quite different of these two,not to mention GBW. 音質劣化についてはFidelixのHPをいろいろ調べてみると、カプリースの内部ルーティングでプリ出力側はアナログボリュームを通過しているようです。さらにヘッドフォンアンプは推測でOPA2134が使われていて、Fidelix特製オペアンプは使われていないみたいです。. Last edited The OPA2134 is similar and spec'd specifically. I'm no op-amp expert but I believe LM4562 and OPA2134 in your list are duals, NE5534 is a single I think and NE5532 is the dual.
