Raven celeste competitors/alternatives

Wish you could hear my Moabs with my Melody tube amp. You would know you are done! Either a Nighthawk or Blackhawk with either Moab or Double Impacts and you will be in heaven! I would go Moab if you have the room, and Blackhawk if you have the money.  

The Celeste are pretty good but they are more in the old-school audiophile realm of being "polite" and soft. Without going into too much detail this is due to the same problem they all face of trying to get a large driver to do the work. Eric by using a lot of tweeters to do the work of one 9" midrange has solved the problem of how to get electrostatic fast response without the hard edge problem everyone still has going the old school route. 

It is not even close, but people get triggered when told it is a $40k speaker for $4k. Actually not a good example anyway, as I am unaware of any speaker at any price that does what his MTM does.  

I go on a nightly basis from Dire Straits to Tchaikovsky and back to Roxy Music and Sinatra-Basie. Moabs do it all, and do it all exceptionally well. Easy to drive. You will find yourself enjoying rock concert levels more than you ever thought possible, while at the same time realize they still are wonderful at low to moderate level. You do not need to crank them up, not at all. But when you do- wow! 

And do not worry about power. Raven will be plenty. Plenty! Just a fabulous combo. Highly recommended!!

I don't have a sub with the Blackhawk and de Capos and have never felt the need for one but my listening space is fairly small. There is some information about their frequency response in the Stereophile review but my affection for them is based on listening to them compared to other speakers I've owned in the same general price range from Merlin, Devore, Nola, ProAc and others.
I don't find it necessary to let the Blackhawk warm up before I begin listening but perhaps I'm not as analytical a listener as some.

Because it isn’t.
It is a $4k speaker for $4k.

You could try the BlackHawk with your Revel's and see how it works. Then there is a Don Sachs Integrated now with 35 wpc using 6L6 tubes. Don's preamp is always sold within 2 days of arriving on the used mkt. And his amp is great. I have one. The waiting list will be 6-8 weeks though, which is the down side. But I suspect his integrated gets great reviews also. Then there's also CJ & other integrateds. I'd love to hear the Blackhawk myself but understand your hesitancy

I agree with artemus_5 about trying a Raven Blackhawk or Nighthawk with your Revel's, especially since Raven offers an in-home trial. If you switched out both at once you'd always wonder whether it was the amp or the speakers making the difference. Call or write Raven with your questions, I've found Dave Thomson to be extremely approachable and helpful.
