cyto Posted April 17, 2011 Share Posted April 17, 2011 I am setting up a 2 channel system for music only. I picked up a pair of KG4's on CL and have hooked them up to a Technics SA-390 receiver that I bought new in 1986. I want to get the best sound from the KG4's so I started by replacing the caps in the crossovers with Sonicap from Crites and I plan to put in titanium diaphrams, if they ever come in. The Technics has pre outs and I was thinking of adding a separate amp, do you think adding an amp will make much of a difference? Thanks Quote Link to comment Share on other sites More sharing options...

The simple answer is....... YES!! Which amps are you looking at? If my memory serves me, the KG's like power, lots of power. [] You'll probably want to replace the Technics eventually, to a better pre-amp/processor, but adding a two channel amp is a great place to start.

cyto Posted April 17, 2011 Author Share Posted April 17, 2011 Thanks for the specs!! [] I was thinking of an Emotiva UPA-2, I have 2 of their subs in my HT system and love them. And what is even better is that their headquarters is 20 miles from my house. But I do not have to get Emo. It will be later this summer before I can get an amp (birthday in August) and I am certainly open to suggestions. If I can find a good used deal I can probably talk the wife into an early birthday present. Quote Link to comment Share on other sites More sharing options...
willland Posted April 18, 2011 Share Posted April 18, 2011 Cyto, Welcome to the forum. I found this little setup that might get you by for a while. I had the exact preamp/amp setup with my KG4's for a while it it sounded great. As the ad suggests, do worry about the lower power rating, NAD rates their amps very conservatively. Just a thought for little $$$. http://nashville.craigslist.org/ele/2314924220.html A couple more suggestions. http://www.audiogon.com/cgi-bin/cls.pl?ampstran&1305941248&/NAD-214-very-nice-amp! http://www.audiogon.com/cgi-bin/cls.pl?ampstran&1307680057&/NAD-C270-exellent-cont.-free-p Bill Quote Link to comment Share on other sites More sharing options...
