Can I get "Great" used speakers for $1800??

I'll second Thiels and Maggies.

New Carolina Audio 6XL's go fo $1800 and are fantastic transmission line loaded 2 ways with series crossovers. Hand made in Charleston www.carolinaaudio.com

I have the JTM's using the Jordan JX92s full range driver and I have never been this blown away by a speaker..... only $1500... I honestly can't think of a speaker at any price that I'd rather have in my living room.

Gershman Acoustics Cameleon, under $1800-, NEW!!! I heard them at both the 2002 and 2003 C.E.S shows, and was floored both times! And at the 2003 show, these speakers were used with a CD player, and integrated amp, with stock power cords, and sounded awesome for a system total cost of around $4500-! Contact me for more info regarding the set-up.

I have seen the EPOS ES-30's anywhere from $1200-1600 used. I bi-wire the mids and tweeters to one channel and the bass to a second to a Sherbourn 5/1500a(5 Channels) using Monster Z2. Four channels used for the left and right speaker and the 5th for a center speaker.
The sound is crisp and clean with very tight bass down to 25hz. The entire EPOS line are renowned for reproduction of Jazz and Classical music. However, The ES-30's, (IMHO), are the only model EPOS that really Rock.
I auditioned many speakers including the B&W Nautilus line. I found the ES-30's imaged and presented a better soundstage than the 803's but they just fell short of the 802's. Of course the B&W name comes with a price tag even the in re-sale market. I almost justified a B&W purchase with the "its an investment" argument but I just didn’t have the cash.

Spendor or Harbeth.
