Krell - Martin Logan power question.

Got a system: Krell kav-500 five channel Lexicon dc-1 4 martin logan clsIIz 1 martin logos 1 velodyne hgs18 1 velodyne fsr-15 neutral reference speaker cables audioquest interconnects Would upgrading to the Krell kav-1500 amp help with soundstage or sound? I am at 200watts per channel into 4 ohms and the new amp would bring me to 600 watts per channel. Please give me an idea how this would modify my overall “sound”. The room is about 20’ by 60’ by 9’ high. The front speakers face the 60’ length. The front speakers are 12’ apart from each other. The rears are 12’ apart from each other. From front to back, the front speakers are 18’ from the rear speakers. So the speakers’ sweet spot occupy the area like a 20’ by 20’ room. I want to use the system for both HT & music. However, I often play my HT at low volume, which helps explain why I use the electrostatics. Please help with this. I don’t want to invest in more power unless I hear from others, but my friends suggested I do so.

Electrostatic speakers like lots of voltage as opposed to current, so high-powered tube amps are a good choice. I also got great results driving my stats with the InnerSound ESL amp, which is specifically designed to drive hard-to-drive ESLs and puts out 2000 VA per channel. It is a smooth nice-sounding amp and throws the most expansive soundstage of ANY amp I've tried with my speakers so far. List price is $3k.

Get a good tube amp with some muscle - Mesa Baron is a good choice for the money - or even the Mcintosh 275 or if you have the funds the new one.

Vettered38, I wanted to ask you about your experince with this. I have the ML (ReQuest) driven by Bryston 7Bs Mono Blocks, however, I have the upgrading bug these days and was considering Mark L 335 (SS), Krell 200c (SS), or SFI Power 3 tube amps. It seam from everyone's response that the Electrostats like tubes. We don't have dealers here so I can try different amp (I Live overseas). So I have to go with some recommendations.
