If you're talking about amp heads: Carvin R600 - $570 Carvin R1000 - $650 Both have the same preamp but the R600 is 600 watts bridged into 4 ohms and the R1000 is 1000 watts bridged into 4 ohms. Do a search on Carvin and you'll find a lot of info.
HA! I knew as soon as I saw Munji's name as the latest reply for this post that it would be a WT-400!
I don't know if you're looking for a combo (or not), but I have a Trace Elliot 1210SMX combo for sale. It's got the 280 watt SMX (with the compressors) brain and 4 - 10's (no horn). It's in absolute MINT condition! I am asking $600 (what do you know!). E-mail if you want more info on the amp. Thanks Bob [email protected]
