Haven’t had the pleasure of testing an original LA-2A but this sounds great. Adds a nice tube warmth, love it as an insert on my Neve and it didn't break the bank!

2A

It arrived and I threw it in the rack and some wires in the rear. Ticking the meter on a vocal I’m as satisfied and smug as can be. It’s doing everything beautifully and money that’s spare will increase my mic options. Incidentally I pushed the ‘73 EQ input gain and I was underwhelmed. I thought I would have enjoyed more head 😮

Warm Vocals

This is my first hardware compressor.. and I'm glad I decided on the Warm.

Using it mainly for vocals and even with very little compression applied I've noticed an incredible improvement in sound.

My ribbon microphone never sounded smoother or more warm. A welcome upgrade from any software compressor I've used.
