Mike, stay with HTS2000, stage three filter in the 2500&3500 models sounds worse than HTS2000 IMO......I have tried both and use only HTS2000, Sam
Bargain power conditioners
Does anyone have any experience using a power conditioner made for computers (ie: the APC Line R 600 which cost around $150) with a high end audio system (front end). It seems to me that these might provide a similar level of protection and enhancement for a fraction of the cost of an 'audiophile power conditioner'. Thanks.
