Eclipse website
CatMan is talking about the high end Eclipse which are the CD 8053 (16\8v preout) or CD 8443 (8v preout)
very expensive maybe at least $350 last time I checked was in spring '03
I have the CD 5433 - the 3rd best in the line with 5v preouts I paid about $280
Well if you break it down they are similar to other HU in feats but the preouts is their main strength
So if you are planning on setting up multiple amps then Eclipse is the better choice
but if you are just gonna power the speakers with the HU or maybe have one amp powering subs then any HU can do the job.
I have to say for Sound Quality Eclipse is the smart choice and for loud booming base any HU can do that except for Sony (lol I heard some bad reviews).
OFFTOPIC: My past HU
Panasonic - lots of eye candy (great visuals), had some good bass but lacked sound quality could be compared to Sony
Alpine CDA 9807 - My fav of the three overall
you get more for the money (looks good, sound was good, played MP3, lots of feats to tune the sound to your liking loved it)
Only reason I gaved up the Alpine was I wanted to see what was the big deal on Eclipse - curiosity got the Kat
Heard could good reviews for: Pioneer, JVC, Kenwood
