BEST LINE CONDITIONER UNDER $600

There is a Tice Solo conditioner for sale on A'gon for $300. It does not constrict dynamics. It does not have an OFF/ON switch.
I own one and it's one of the best purchases I've ever made. It has completely silenced the noise from my apartment outlets. Highly recommended (no, the one for sale is not mine).

How about a 20A dedicated circuit for your HiFi? And money left over toward power cords. Happy Listening!

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.

There is (or was) a Tice Power Block III on Audiogon at $500, an outright steal IMHO. Two audiobuddies and I have this unit and like it a lot. Dave

Hi,
If you swing it there's a used Running Springs Jaco unit for 900 on A'gon.I have the Haley absolutly the best conditioner out there ,not advertised much so you'll have to search around and you'll see how well regarded it is.No I'm not afflilated with the co. but a very happy customer.
Will not restrict dynamics in fact makes it seem you've done a 50% upgrade in your gear.
