Quality used amplifier needed


I am in the process of upgrading from an Adcom 555mkII that has been modified. My friend has a Threshold S300mkII that I have heard on my system and it sounds fantastic. Are there any other used amp I should look at in the under $2000 range. My speakers are 4 ohms and I feel I need an amp that put out 300 watts at 4 ohms and is also able to deliver high current. Thanks, CS

I would consider McCormack DNA 1 Check out review in stereophile. I have owned one for 3 years and love it
See my ad for Kinergetics KBA 75. I own a hi-end company www.audiotweakers.com. This amp has been in my personal stash for 4-5 years. With the right complimentary equipment it competes with anything. Retail $1995, plus $300 power supply mod- sell $995 OBM. Pure Class A doubles down to 300 w@2 ohms. Weighs 50 pounds. FIrst class all the way.
Try to get your hands on a Aragon amp. I own a 4004 and while it is an older unit it will drive ANYTHING. Very relialble amp. Enjoy the music.
