Silky smooth

I own several boutique pre-amps to compare to and the LA-610mkII stands shoulder to shoulder with them. It possesses a tone unlike the others especially on male vocal...Silky highs with punchy low mids and just enough air. The preamp and compressor work very well together where you can hit 10db of compression and barely hear it working. Very smooth and musical for tracking vocals. Like an LA2a it is very easy to set up. Everything feels solid. Switches and knobs have a positive feel and seem high quality. For a vintage modeled piece it actually has a pleasing modern tone and not dark like some reviews have stated. It's definitely warm but possibly because of the smooth mid range. If anything it has a well-balanced tone that will work well on many lead sources. On the bad side, the preamp can be overdriven slightly if not careful. Watch your loud passages and set your gain for that. All in all, I'm loving this piece. It has a color unlike my neve style preamps and it fills that lush and opulent side of my tool kit. Smooth and punchy. Delicate and tough. UA has a winner here. I'm in.
LA610MKII kicks big time

So after months of research on pre-amps/ channel strips and after watching UA's video on the original UA 610 console. Takes some getting used to for vocal/mic settings, but it has a TON of sounds from clean to colored. Built like a tank and will be in my studio set-up as a main piece for years, if not the rest of my life. Highly recommend it.
Wonderful unit

When first building my recording rig, I spent a *very* long time reading up on which preamp I wanted to start with. I was already using a Focusrite Saffire PRO 26 and 10, so something a bit colored was where I was aiming. I went ahead and went with Universal Audio because I was familiar with their higher end hardeware already. Aside from my beloved Cort MGM, this is the best bit of money I've ever spent on something music-related. The sound is incredibly smooth and a bit on the darker side. The compressor is beyond excellent and the EQ gets used a lot more than I had expected. The only real flaw is that it sounds so good, it becomes your go-to pre -- using it on too many tracks on a single song can muddy things up.
A MUST HAVE FOR ALL STUDIOS

Its a excellent preamp and the optical compressor side is just unbelieveable, no distortion at all and very warm sound, Universal Audio hasnt let me down yet.
