Tact Pre Amps 2.2XP

Hi Bob- I wouldn't add anything else to the audio chain personally. I can't really imagine a need. I still abhor overprocessing signals, and adding interconnects. The TacT does act as a pre-amp(adds SOME gain)and (as mentioned): is capable of more with the power supply upgrade(digital clipping is nasty). If you're thinking, "tone controls": The TacT has a bass/mid/high shelving control as well(even better if you need it). One of the niceties of using the Tact is moving the subs into the room corners, and being able to time align them with the mains. Having crossed mine at 300hz/60db per oct has increased the system's dynamic range greatly. Much more power available with the bass/low mid duties removed from the tube mains. My subs are transmission lines driven by a trans-nova 9505(high damping factor/slew rate), and agile enough to match the speed of my Maggies. That's important for a seamless bass/main transition.

I forgot to mention: Lyngdorf uses a 10" woofer that possesses extreme transient speed/efficiency. Available here: (http://www.audiosystems.com/NewComponents.html), as well as their complete corner-woofer system(You have to query him concerning the raw drivers). I believe the guy offers a kit form as well. With these 10's on the bottom: You don't need a monster amp, or have to worry about matching the transient response of your mains.

Thanks for all the comments and insight. The question is TacT 2.0S vs. 2.2 XP. I do have a 15" Velodyne subwoofer but live in a condo so it's in storage. I'm torn between buying something I can use now and upgrading later or growing into an overspec'd unit when I move in a few years.

The XP has WAY more functionality than a 2.0s. I've owned the 2.0s, the 2.2X, and the 2.2XP. The XP has processors so fast that ALL corrections are done instantaneously.

You don't have to use a laptop, but with the XP connected to the laptop you can play with XO frequencies, slopes, target curves, and even the unprecedented dynamic room correction, which is basically a variable loudness control.

Boz told me recently they're working on a crosstalk elimination function that will keep signals from the left speaker from going into the right ear.

This also shows something cool about the XP - it's still under software development where I doubt the others are. As they release new functions, they become available by easy download. It's not future-proof, but it is still current and a kick-ass piece of gear.

I don't have any experience with mods to the units, but I've heard nothing but good. One thing - I don't like the stock DAC sound. Maybe it's primarily the power supply or the DACs need better parts, but overall I have enjoyed outboard DACs out of the digital outs much more than the stockers.

Wonder what that does to the sweet spot.
