I've been using UAD products since the early 2000's, even before the host (Digital Performer) and the UAD cards could compensate for latency. The sound was so good that I manually slid the tracks by twice the buffer size in samples to align them, such was my urge to use UAD plugins when needed. Eventually I outgrew my system and my old UAD-1 cards remained installed in an unused G5 computer. I recently bought a UAD-2 Solo-laptop, and regained immediate use of my plugin library (no other manufacturer allowed me to use a 2000's plugin without several paid upgrades), so I went on and ordered 2 Apollos and 2 Satellite Duo's, one system for the studio and one for home. Haven't got the Apollos yet, but the Satellites and Solo rock big time. Kudos
