Amplifiers:A Keeper for Life. Do you know of one ?


Just wondering, with this audio merry-go-round of buying and selling, if anyone has an amp that will be a keeper for life. I haven't yet but came verrrry close once...

Any Spectral Amplfier. Though the evolve, there is a basic house sound that is clear and detailed. During the CD evolution, some found this sound thin or too detailed. Now that we have excelent computer driven DACS and servers, as well as resurgence of Vinyl, you can appreciate the life like quality of the music, without any added tones.
I feel like my BelCanto ref1000ms could be based on their outstanding performance yet I know Class D amp technology is still relatively young and will likely continue to improve over time (more so than other older more established amp technologies) and I am curious exactly how far new technology might yet push the limits accordingly down the road.
My TRL Samson monoblocks. Good power, clean sounding, and run cool. The previous owner had immediate seller's remorse as soon as he sold them to me. I won't make that same mistake.
If you love amps, there's more than one: LSR&D Superamp monos, Meridian 105 monos, Acoustat TNT200/120, G.A.S. 500, Bedini 100/100, Sunfire Signature 600-2, BEL(Brown Electronic Labs), Perreaux 2150b/3150, to name a few. But imo, the holy grail would be non other than the elusive Yamaha MX10000. Haven't heard nor seen one except on the net. One came up for sale on CAM a little while ago. Like the Scarlet Pimpernel, it appeared and then disappeared without a trace! Wonder what happened there?
