I have a Carver TFM-42 (probably in its last days--I'll have to look into repair recommendations on this site). Thank you for clearing up the matter. For a time, I thought it was the victim of a factory-second situation. I am looking into purchasing a Sunfire Processor (I am borrowing one at this point) because it has the digital and most recent version of Holography. The one real drawback, I suppose, is that I really do not intend to use it for a 5.1 or greater system. I am not especially interested in home theater, so I am looking to update a two-channel system. The Sunfire Processors offer far more features than I ever intend to indulge. Unfortunately, the tube processor that Carver/Sunfire made available seems to be for the purist as it does not include the Sonic Holography option, one of the main draws for me to look into Carver equipment from the beginning. Thank you, again.
