You recon that s because of increased mojo driving hardish speakers or because of increased thd? Or perhaps a combination?

Same coin, different side, although you do get a little more yfs and a little less Ciss, but you got to cook it to do so. Might have to order some and see. Does it have a twin?

The fact that some of us can't get any R100s is more a tragedy than a joke.

Yup, the Zen Master must have horded some after he got some insider info of SS's impending demise.

I must need to go and travel to other side of iron curtain to provide some friendly persuasion for some R100 gifts.
