Ozzy,
Most welcome. I have a dedicated 20-amp line for my audio system. I think it will come down to the quality of the transformer. I don't think you will find another one like the one I bought -- in the enclosure, made in Germany by Block, with the toroidal encased in resin. But Tripp or another inexpensive unit may end up doing the same job as mine in your system. I can only speculate. All I can say is I gambled and won -- big time.
During the decision-making process, the big issue for me was the weight. Some of the units out there weigh from 70 to 100 lbs. or more. I live overseas. The shipping cost for one of those heavy units put the purchase out of the ballpark. My unit is compact and weighs about 40 lbs. double boxed.
Regarding size and weight, I think Tripp are also within reason. Frankly, I would have gone with one of their units if I had not bought mine. But I have no idea if their toroidals are encased in resin and if that makes a difference re: the sonic benefits. Theoretically, according to what Bombaywalla has to say on the subject, a well-chosen Tripp unit should be able to give good results. I have seen them for about $100 on Ebay -- mint. Worth the gamble, IMO.
