Antique Sound Lab Amps

I have also been looking at ASL amps for my JMR Twins mkII's the last few weeks. I wonder what's the sonic difference is between the MG-SI15 15 watt SE integrated (KT-88's) and the KI-15 15 watt SE integrated (6x6AS7's)? Too bad I can't find any dealers here in the Los Angeles area to demo the units. Since I'm going to augment the Twins bass with a powered subwoofer, I can go for 10-12 SET watts for superior sound. BTW, Pretender and Gebou5 - Have you noticed an impressive difference in sound between 125 and 200 hours on your Twins? The bass has become so much more developed (and deep), and power handling has increased substantially along with overall tonality. I have a Rotel amp and pre-amp driving them and can't wait to hear valves w/ the Twins. Affordable Perfection?

Wow, Pretender, you move quickly! If you think that your speakers sound impressive now, wait until 200+ hours. A whole different level of performance and it doesn't stop there. Dekay suggested that I first try a Doc Bottlehead Foreplay tube pre-amp for $99 ($180 w/ full upgrades) w/ my Rotel amp and see how that sounds. If the Foreplay is 2/3 as good as people say, then I can live with my Rotel for a while longer while I save some dollars for dual monoblocks. Eventually, I'd move the Foreplay to a better looking chasis. Seems like a cheap way to get some good tube sound!
