    The BA312Ms are quite the overall improvement in the tightness of the bass and it lifted the kinda blanket over the speakers in the high-end. Ran into an issue with one wrong hole cap leg placement but end result was ok. Nice upgrade for sure and great direction sheets..Thank you.

    Highly recommended!

    I rebuilt a Marantz 2325 and when I got done with the tone board it still had a weak channel. I traced the problem to one of the obsolete BA312 chips. I ordered and installed this kit and it made an incredible overall sonic difference in the 2325's performance. The instructions were clear and the parts are high quality. Highly recommended!

    happy

    I have other issues with 9090db receiver that need addressing but sounded great more open for short time I had working. Hope to have it a 100% shortly after total recap and getting bugs out. 9090db's are finicky but worth it sound wise thanks Bill and thank you Andrew

    Game changer

    As if a thick veil was lifted without changing the vintage Marantz sound.
