The Adcom unit was the first conditioner I had ever bought, back in 1990 or 1991. It worked well to my ears, with an audible improvement. I do not recall any dynamic restrictions. I have since gone through several Tice models, the latest and greatest for me is the Tice High Current Solo unit (now unfortunately only available used as Tice has closed doors). I recommend the Tice Solo or even better the High Current Solo. No restrictions that I can hear.
