Hey Lissnr,
How’s it going! I sure am enjoying the Mundorf Supreme EVO Silver/Gold coupling caps in the V12R. While expensive, sounds amazing, took at least 200hrs solid playing time for break-in but very pleased. A big-time SET amp/customizer friend of mine listened to the amp with these caps and updated hexfreds installed with his big Altec/Onken horns speakers in Triode mode commenting how nice it sounded after he and a few of his local audiophile buddies listened to it. I was playing recapped V12R with my regular old FM tuner the other day, and was really liking it, how could FM sound so nice... hahaha. Sounds full and musical with any feed, streaming, fm, CDs, whatever... . I like them so much I’m now considering putting them in my tube DAC and might remove the Jensen Oil/Paper caps in my SLP98 preamp. They have an open, expansive, yet detailed sound without being too velvety is how I’d describe it. Another west coast builder is offering them now in his amps/preamps standard now. Hope all is well, and you are enjoying those TRL amps. Take Care :)
