CLSII to CLSIIZ

[legarem]

Hello
I have a pair of CLSII and I looked to modified them in CLSIIz.
Many peoples wrote that The CLSIIA plays better than CLSIIZ. The CLSIIZ was only created to be easier for amplifiers.
Is it thruth ? The CLS IIz with the mods will be at 12db/oct instead of 6db/oct with the crossover. This is something which worries me with phase.
Should I do the mods to CLSIIZ or just upgrade the CLS2II to CLSIIA with better parts ?
I have many amps to do the job at tough loads without problems.
Thanks a lot

At one time I owned all 3 models you are inquiring about. The IIA and IIZ I owned at the same time. For me the IIA did offer more bass but not a night and day difference.

So If I have a good amp, I could go for IIA for best sound ?
Thanks a lot
