new speaker for shindo amps - 70 watts

Call Jonathan Halpern, the Shindo distributor.
He'll know better than anyone.

For such a high quaility amp like yours, I`d also give serious consideration to Coincident, Tonian Labs and Horning as excellent high sensitivity-easy load brands.

Those are great suggestions, but if you want to go the purist route, check out the Altec Valencias or for the ultimate in synergy - Shindo Latour which are a field coil design.

I own the Silverbacks in my reference system and someday hope to upgrade to the best Shindo amplification I can afford to best compliment my Shindo Masseto. I have heard the Shindo Latour's, Altec Valencia 846A's, and the Silverbacks with Shindo electronics. All quite different from each other in terms of musical presentation, but they have one thing in common - sound to die for.

when I used Shindo amplifiers, I always had Altec speakers...model 19 or 604 in 620 enclosure......
