Great advice above from these guys...8 wpc isn't going to cut it.  While you're looking at Latinos perhaps the ST70 he builds would sound better than the big 120 with your speakers.  I've found that smaller tube amps ie with just enough power to get the job done right sound better than overkill big tube amps.  Have fun!

rodulfo23,

My Audio Note Kit One 10th Anniversary 8 watt 300b SET did a good job with everything including rock on my efficient Klipsch speakers, and it also did good bass...low and detailed; BUT, it wasn't as visceral as I wanted it to be on some of this music at higher volumes, so I decided to go with an EL 34 amp. That said, if I could have afforded to keep the 300b, I would have. Remember though that the 10th Anniversary has the double C core transformers, and that makes a difference. It is a really sweet amp, and I would buy it over again. It was also completely reliable, and never gave me any trouble.
