M5218 opamp substitute?

EIRA · 16th February 2005, 09:39 PM

I have a Denon DA-500 external DA converter. It uses M5218 (Mitsubishi) opamps. I was wondering if it would be recommmended to change them for OP249, OP275, OPA627 or AD797NA opamps?

Yes,why not?.Personally i choose OP249 as it sounds natural to me. Datasheet of M5218 is available at www.datasheetarchive.com

Thanks, LeoLabs,
I collected various DA-500 mods from different threads. In case you have one, I can send the doc that I made out of it. I do not understand all of it (bit newbe

), but it is a good list, I think.

I had the same Mitsu op amps in my CDP and I swapped them with Nat Semi's LM4562 with great success. The OPxxxx op amps that I swapped in just did not sound as good.
