Notes on Audio Op-Amps
« on: Jul 19, 2005 at 10:13 AM »
Some listening tests were conducted on the ff: op-amps:

OPA2107, OPA602, AD825, AD744, AD797, LT1028, LT1115, LT1122, AD826, NE5534, NE5532,
OP275, LF356, and LM386

and the results show that the OPA627 and AD843 come out on top. Below is the link on the full
review. It also comes with a steep price (literally).

Ako rin ADI din ako. Wala na nga palang Burr Brown at binili na sila ng TI.

Date nga pala akong Test/Product Engineer sa Analog Devices kaya lang hindi ko alam na pang audio iyung mga op-amps. May hawak din akong op-amps mostly using BiFET technology. Mayroon din akong hawak ADC/DAC na pang audio. Alam ko iyung mga op-amps pang test equipment lang kasi panay precision op-amps iyung mga tine-test namin.

That's OK, you can like or dislike anything you choose. That's the wonderful thing about the freedom

Sir 2ny,

Am willing to lend you my differential amp samples (some) for the op-amps. That way we can validate the sound of these chips ...

I have a pair of brown dog adapters on stock (last ones).

The minimum purchase from the Internet is 5 peices. These are left-overs from my op-amp rolling "adventures" using AD8066.

Text to 0917 853 4185 if you are interested to buy. I'm giving this to you first, but if you will not be interested then I will post it in the Buy and Sell section.



Thanks.
