Amps for Chorus II - 2 Questions

Recommended Posts

1) I'll be running my new-to-me Chorus IIs with an Adcom GFA-585.....250 stated watts at 8 ohms. Is that a good match....too much.... not enough??? Any comments/thoughts on the Klipsch-Adcom marriage in general???? I got the Adcom GFA-585 just a year ago and it seems pretty solid, thought I haven't had the top off and I don't think the original owner I got it from had any work done to it? I know I might need some work to the capacitors and there are some "upgrades" out there......

2) I really wish I had some way of measuring the wattage output on my my Adcom system. Since 1987 I had my original Adcom GFA-545 amp, rated at 100 watts, paired up with my KG4s, also rated at 100 watts at 8 ohms, I always knew that when I started to see the clipping lights flicker that was all the volume I was going to get and I backed it off a little. Particularly since my KG4s are only 4 ohms (so the amp was pushing 200 watts with them). I've only had one of the tweeters on the KG4s kick off about 5 times in 27 years. Nice feature!! Anyway, I was a little surprised to discover that I could not find on ebay/online a good looking, quality "audio output meter." While we all know most McIntosh amps have them, my Adcom, and many others, do not. Anybody ever just arbitrarily add a set of meters to an amp?? I found some basic McIntosh looking meters on ebay/on line and thought of just adding them....somehow....... Any guidance welcomed!!

The amp power should be more than enough. Try it and see how you like the sound. 20-40 watts will propably make you want to leave the room or get the wife screaming, lol.

With the efficiency of the Chorus II you will drive yourself out of the room before the speakers consume the 200 watts output of the amp or damage a driver. One thing you may want to consider is replacing K-79-K tweeter. It is a polymer dome tweeter and it sounds OK, but IMHO the Bob Crites titanium replacement improves the sound.

IMHO you need something with some omph to get the woofers moving. I have had a few sets with the same results on all of them. My Marantz rated at 125wpc didn't get the job done. An Emotiva that runs in 2 channel at approx 300 wpc made a big difference. Congrats on the speakers!

Mine are hooked up to a late 80's or nineties Kenwood under 100 watter in a live room. There are no issues getting the woofers moving.

The chorus ii are my all time favorite speaker. I have a couple 200watt adcom mono blocks than run them very nicely. My choice solid state setup is my adcom pre with a bbe882i with a crown xls2500. I have pushed them in this setup to 116db @ about 5ft away and sounded clear and just left that test at that. So the listed 120+db is true. I run them mostly on tubes at about 60wpc now and they are also very happy sounding. chorus ii can eat up watts with the best of them specially for a full range "home" monitor

edit: you will be set for life with your adcom amp. they go together very, very well
