Arc PS8 guts!

I was upgrading the OP amps in my PS8 and thought I'd share some pictures of the inside.

What do you hope to achieve with the upgrade?

Upgraded them to the LM4562NA. Made a noticeable difference in sq. Definitely worth the $15. Overall system got louder and more musical. I noticed the biggest difference in the highs. Louder and softer and seem to come through a lot more.

Overall I'm extremely happy with it. I honestly didn't know what to expect. I had them for almost a year and finally decided to install them out of boredom, change in sq was a pleasant surprise.

I'm honestly surprised it didn't just come with these to begin with. The PS8 already sounds really good, the upgrade just takes it to the next level.

I need to get a good tuning session. I still haven't tuned them since I installed the midbass drivers in my doors.

You're just boosting the pre-amp signal? Looks like plug n play, no soldering. Cool!

Different op-amps have different sound characteristics. It's not just about gain.

Just dropped right in. Took about 2 minutes after I had it opened up.

Really impressed with the sound, my beryllium tweeters sound so good now.
