Atmasphere, Weseixas answer is very vague plus his statement that an amplifier should have the ability to drive a 2 ohm load otherwise he considers it midfi, is misleading. But if you do some searching under his user name you will see that his statement reflects his frustration to find an amp that will drive ribbon speakers. -Phd
No frustration ,
I can build my own ( i have) or buy what i want ( done so 2 ) A true high end amp should be a perfect voltage source IMO, end of story.
Atmasphere:
Sound is very subjective, one man's euphoria is another' anathema. An amplifiers job is that of an voltage source, expensive high end amplifiers that cannot replicate such, is well ................
A Pretender.
