I'm lucky to live with the JBL 4425 and a little Mcintosh MC225 tube amp. Although the 4425 is not the high-end level, it is good enogh for me.
My setup is:
ASR battery pre-amp
JBL4425 & ESS AMT Tweeter
I 'm very impressed by the lovely hi & mid- range of this setting. However, as you may notice, the mc225 is not powerful enough to drive the 12" woofer. I know the solution to get enough power while maintian the beautiful hi & mid is to go for a Mc275. But it will burn my wallet.
I'm considering to send out the ASRpreamp and Mc225 and get a Mcintosh MA6900 intergrated amp. The question is "does this solid state amp drvie the horn well??"
I won't expect this matching can deliver the same hi&mid range quality from Mc225 tube. But I'd like to have more exprience speaking on McIntosh Solid State driving horn speaker.
