Maybe next year project will be a MarkAudio fullrange speaker.

Wrong answer, Try Again.

No, I feel the same pinch but am hoping there might be a suitable low cost driver or a "Midnight-Blue light" special that fits into a simple MFB box. Still looking.

and FYI - I had to sell the refrigerator to be able to buy the True Copper Caps.

I've been lucky, I've had to sold only my microwave owen...

At least at the end we'll all have a zen house full of music

One is a pair of JBL LX2001 bookshelves with a 6" woofer, 1" tweeter and 2nd-order XO; another is a Jamo Compact 60 with a ~4" woofer, 1" tweeter and 1st-order XO; and the third is a Kenwood LS-M33V bookshelf with ~4.5" woofer, 1" tweeter and 1st-order XO.

A speaker upgrade is on my wish-list, but I have lots more stuff on my plate now, so it will have to wait for a bit.

Hi Siva, Sorry for a bit of misunderstanding. I was following squalor's lead. Thought you had a FR.

Thanks for responding.

squalor - you have to go stand in the corner for ten minutes

P.S. Did you settle on a name for project X yet?

Dario, I'm hearing lots of "fuzz" on things like Wynton Marsalias solo trumpet work in the upper regesters. Is that what you meant by HF distortion with the Elna Cerafines? Everything else sounds pretty smooth,warm and punchy. Cymbals are clean and bright and the drums and bass are distinct.

I wouldn't call it distorsion but there's something wrong with HF.

It depends a lot on recordings, if HF is on the hot side in my systems high hats and sometimes voices and trumpets get a bit of hardness and harshness.

Ditto - very source dependent. I'll have to make note of where I hear it so I can compare when the FGs arrive. It is a very good sound otherwise. Sounding quite clean and responsive now on a light classical piece - Overture to Hamlet.

Dario, I saw in post #11 that you are using r-core transformers. I've been reading on a few sites and the consensus appears to be R-cores for DACs and Preamps - toroids for power amps. Is there anything about the FE that would dictate a preference for either type?

And - other than the standard LM3886 specs, what would be your recommendation for the highest allowable trani rating for this design? Just thinking ahead on final build/chassis configuration.

Actually, I had done some auditioning earlier with a friend's speakers which had Fostex FE206 FRs, so that's what Squalor may have been referring to.

MyRef_X2 sounds fine, unless some objections crop up. I'll wait for another couple of weeks at least, until the prototype PCBs show up.
