I really like the Topping TP-60. It got a better bottom than my tube PP and bit crisper top. I have to admit that the music I listen to sound better crisp than the soft warm sound of a SE tube. I am waiting patiently for the new TI class-D chips to reach the boutique market. Rumor is that they are much better than the Tripath chips.

I have a SMLS sa-s3. At first I dindt like it very much, nice but not close to my
Yarland FV34A single ended tube amp.
Then I decided to look at it as a power amp and I put a Atoll pre-amp before
it and then magic started to happen. It is now way better than the Yarland and
anything I had before.

Back to the topic. I decided on buying two pairs of EL70.
I want to do several designs with them. Start out with the micro-towers.
Later I want to build the bipole Metronomes. And maybe try a bipole ML-voigt (if that is possible).
I will be posting about results. I am gonna build them in my father's workshop
(professional tools at hand), but things will progress slowly due to health
problems of my mother.

How does the castle orientation work when it is placed out in a room? I have a multi level great room and the speakers would need to go against a 30" high wall which extends out 15' horizontally and 8' vertically to a loft.

If this means a 30" high and 15' deep platform /"stage", then I'd imagine that the Castles would loose one of the performance characteristics that I think contributes to their soundstage dimension - the reflection from rear / side wall boundaries.

Pretty much what it is like. I was think that might be the case. You basically wouldn't have any rear boundary reflection. The top driver would be radiating up to a ceiling which is 8' above it. I guess a front radiating speaker would work better in this situation.

The high ceiling should allow the castle config to fill in the baffle step and still retain the image specificity of a monopole. The top driver should also help fill the space for those not in the listening window.

I agree with Dave. My gut tells me that the Castle would still offer benefits, just not in the same manner as it does closer to a wall.

I am not anticipating these speakers will be used for high quality listening. I was thinking they would be fine for background music without leaving a lot of null spots in the room. I currently have in wall speakers on a side wall, which sound OK for TV sound, but poor for music. I could always build them and see how they work. If they don't work, I could always use them in the basement theater as surrounds. How do they work as surrounds?

Sounds to me like they would be suitable for any of the situations you have described.
