Aragon 8008 bb vs. Krell KSA-150

I'd buy the 8008bb and call it good. They're much less money and newer. If you buy an older Krell that runs pretty hot I'd plan the possiblity that it could use some new caps. Same person designed both amps. The Aragon is also a brute. When it comes to sound you pretty much have to try it in your own system anyway. That's the beauty here on Audiogon as you can buy used and not take much of a hit if you don't like it. I'd be very surprised if the Aragon didn't work out well for you though. Good luck.

You're on the right track. Just keep reading. Something that will help more than an amp, preamp or dac is room treatment. This can be fairly inexpensive and reward you with big dividends. Your system will not perform as well as it could without room treatment. When you improve your room acoustics you'll be able to easily hear it. Realtraps.com has good articles and there's an acoustics forum at audiocircle.com that Ethan from Realtraps frequents.

Most of us learned many years into this hobby how important a good acoustical environment is. I'd consider it early in the game. By all rights the room should be the first thing considered, not the last. Best of luck to you. Audio is a great hobby if you love music.
