Dazed and confused


I own a pair of Coincident Super Elipse III's that are suppose to be 94db and 14ohm," able to be driven by anything". Then why did my Cary sli-80, 80 watts per channel( kt-88 based) integrated amp drive these speakers so much better than my VTL it-85 80 watt (el-34 tube based) integrated amp? The VTL does not have any where near the punch and runs out of "steam" very easily. My Unison Unico drives them better yet, I assume that is an electrical current issue? Your thoughts would be appreciated.
Thanks
Mike

If there's nothing wrong with the VTL, then it may be an impedance issue. The Cary and Unison could be switched to an 8-ohm output. The VTL, I think, is only a 4-ohm output. Fair amount of power is lost from a 4-ohm tap into a 14-ohm load.
My el-34 tubes are not as powerful as my kt-88 tubes in the power amp. I guess that may be a reason. I used to have the Coincident with Cary SLI-80, and just loved it.
VTL output transformer should be rewired for 8 Ohms.
I can send the VTL colour code info of the output transformer.
You gentlemen are correct. The VTL is wired for a 5ohm load, why I dont know. If it will help too rewire it that would be great. Please explain to me why it make a difference.
Thanks
