what should i keep, shindo or mcintosh

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?

McIntosh C2300 will be around long after Shindo. Nothing against Shindo but with this market slowly dieing survival will be tough for the big names, the small ones I really have a hard time buying.

What happens when they are gone who going to repair it? Shindo is getting good reviews but that does not mean success and a long market life.

"Shindo is getting good reviews but that does not mean success and a long market life."
... Shindo has been in business since 1974 with Shindo Laboratory Inc being formed in 1977. While I can not predict the future, I'd say the track record shows they're not going anywhere. I also believe you have it backwards- the small guys with low overhead are more likely to survive, the big corporate companies will more likely fail should the market "die." However, I do not agree its dying.

BTW- this post died nearly two years ago.
