Speakers for Sansui AU-666


I'm currently on the lookout for a pair of speakers that would complement my vintage Sansui AU666 integrated, which i use in my bedroom system with a Dual 505-3/ OM20 and computer w/uDac as sources.

The room itself is approx 14' x 9.5', with the speakers on the long wall, at the foot of my bed. Carpeted.

I'm currently running Rega Aras on stands and, although good, I feel there would be a better speaker for this amp.

Bearing in mind the amp's amp's vintage, the room size, the limited space for speaker placement and the fact that the room is acoustically dead (primarily due to synthetic carpets, which i think suck the life out of speakers), does anyone have any idea of a solid speaker pairing?

In some ways, i was thinking about Klipsch Heresys, but there is a voice in the back of my head that says not to go that route.

Old Dynaco A10's or A25's, which can be had at very low cost, are other speakers I was thinking of as a potential.

JBL's come to mind as well..L100s or L110 (don't know if these are too big for the room, though)

Perhaps Yamaha NS series speakers...

ADS is yet another...not sure of which model, mind you. Perhaps the 570?

All of these speaker options are vintage, however, i'm not opposed to a new speaker that would work in my situation. To be honest, most modern speakers I've tried in my condo do not sound good due to room acoustics (which i cannot change). I'm starting to think that vintage speakers are the way to go.

Any thoughts and/or suggestions would be much appreciated.

I have owned the same amp, I still own a pair of the Dynaco A25xl's. I updated the tweeters after the originals failed. There are very nice replacememnts that drop right in. I used SEAS Prestige 27TFFC (H881) Textile Dome at madisound. I am still amazed at what these old speakers can do, they also have a knob in the back with three settings for bass, neutral, treble. I have them placed on some DIY speaker stands. Enjoy your search.
Bozak, eh? I've never really read anything about them, let alone heard them (i've heard OF them). I'll have to read up on them..

Musicrover: How were the original tweeters on the A25s by comparison to the new ones? Did these Dynacos only come alive w/ the new tweeters? The reason i ask is b/c i wasn't likely going to be modding any speakers i purchase (not to that extent, anyway...although now you got me thinking...)

I just found a guy relatively close by who's apparently got a ton of vintage speakers (and receivers, amps etc), including many of the ones discussed here. Hopefully, i can get a chance to make some direct comparisons. Can't wait!
Actually the ES14 is an easy speaker to drive with a nominal impedance of 8 ohms and a minimum of 7 ohms. It is basically crossoverless so nothing to rob power in that respect.

Price on JBL L 100 depends on condition.
Loose - The Dynacos have a very good sound with the original tweeters, However with the new tweeters they took another step up IMO. The tweeters are very easy to replace just a few screws to remove and connect a couple of wires and you are in business. It was worth the cost for me.
