Recently purchased a 6U SKB ATA rack. I currently have a furman p-conditioner and a tuner in it. I have a svt4pro but am looking to change amps because i just bought a 4ohm eden 210xst and a 4ohm 210xlt. When I run them stereo out of the ampeg head i dont get enough power to the xst, because the xlt gets over powered and i just dont think the amp has enough headroom to push this. I use a modulus quantum 5 , often with a pick. So, I am going to get a preamp / power amp. I have been thinking about perhaps the eden wp100 navigator , or an alembic f-1x pre's with a QSC GX7 - the gx7 has 2 channels so I can send different amounts of power to each cabinet ( correct? ) I am looking for advice between which pre-amp to get, money is not too much of an issue. Also, the eden pre and qsc power would fill up every slot of my 6U rack with tuner and PCond., would i have problems with overheating??? Any advice is much appreciated.
