Best 3 options for SET amps

Fernando, if you are limited in space, the Cain Abbys do have a fairly small footprint and can be placed failry close to walls. The size of the speaker is not necessarily correlated with the space they will need to sound good. From recollection of the 3A De Capo, I do think the Royal Master might need a lot more room to breath.

Also, another option not mentinoned so far are traditional horn speakers like Klipsch, Altec, etc. They usually do require large space though.

All these speakers have a very different design and as result very different sound with different tradeoff. Listening to a couple should help making up your mind.

Good luck,

Gliderguider, now that you opened pandora's box...What amp did you use
with the Abbys?

In general, high efficiency speakers seem notoriously difficult to match with
the amps. The Abbys sounded downwright awful with a Jolida 302b amp. A
Bottlehead SEX worked well, but was misisng bottom end. Both the First Watt
F1 and the Fi Super X sound incredibly good for the money. Also, I had similar
experience with the Zu Druids listening at dealers. As you state, the Abbys do
have their limitations but then you would expect that compared to your $10k
FAB speakers ;). With the right amp they shine.

Getting back to topic though that is trying to answer Fernando's question:
Given that you started with the amp, you will have to carefully search for the
right speaker that a) you really are comforatbly with and like and b) matches
your amp. Given that speaker tastes differ substantially (as you see from this
discussion), I would prefer to go with the right speaker and then find the
matching amp.

Of course, as the obvious choice for your Audio Note amp, my guess would
be to go with Audio Note speakers. Any of the mentioned speakers might
work or not, but only your ears and amp can decide that.

Good luck,

Rene
