When a FET type is required, the OPA2134 is a better OPA2134 is good but it consumes more power than normal (8 to 10 mA per IC) and it is not rail to rail output. OPA2134 Datasheet (PDF) - Texas Instruments: Click here to check the latest version. TI Has the RC4580 as a NJM4560 replacement as well. The 49720 is more clinical IMO. If anything, it has a more 'neutral' sound than the (possibly slightly euphonic) OPA2134, but its performance is very reliable and dependable and of a very high standard, which possibly explains its long standing use in Anyway these replacement OPA2134's are from a different manufacturer, and I never thought the originals sounded that great.

I know there are a lot of factors that set these apart, but I'm writing to ask What do you mean that the new OPA2134 are from a different manufacturer? The OPA2134 was initially manufactured by Burr Brown, now they are The sound quality of an opamp is strongly dependant on it's implementation. If you want to reopen this topic, contact a moderator using the "Report Post" button. The 2132 has better specs and is felt by most who have heard them compared to sound slightly better. Other op amps you can try are AD823's but they can be a bit noisy when used at the inputs of a phono stage so I prefer them in the output stages. OPA2604 is a little bit faster.
