what should i keep, shindo or mcintosh

Not sure if I agree that the Shindo preamps do not have punch. My Masetto has lots of punch with my Lamm ML2's. It bettered my Wyetech Opal in this regard and I felt the Wyetech was one of the best I had heard.

I am currently running Reimer Teton full range speakers 95db (4ohm) with Lamm ML2 amps. The Tetons go deep and tight in the bass. Not sure how the Shindo amps may compare with the Lamms but the Masetto has great dynamics in my system.

I disagree with your blanket statement that Shindo amps are only for horn speakers. All the amps are tube but some are single ended some are push pull. The 8-10 watt amps do need a fairly efficient speaker but there are many efficient speakers that are not horn speakers. Coincident and Audio Note come to mind. It might be helpful for us to understand where you are coming from if you shared with us the combinations that you have listened to that you didn't like. Also what type of music do you tend to listen to?
