Piega and tube amps


I am interested in buying Piega C-8 LTD speakers. They are rated at 92 db into 4 Ohm. I have called a number of dealers and read a couple of reviews and get contradictory advice regarding necessary amp power. The Piega website recommends 20-250W, but some dealers/ reviewers recommend large amps. I would like to drive the speakers with my Joule Electra Stargate amps rated at 30w/ch into 8 Ohms. Does anyone have any experience driving Piega speakers with smaller tube amps? Any feedback would be appreciated. Many thanks!

I have been using Conrad Johnson Preimeir 12s 140 watt monoblocks.& a pair of Bell 1001s alternately with my C8LTDS with excellant results.I think you would need a higher power amp then you plan on using.Great speakers by the way.
I have used a Belles 250i integrated, a Rowland model 10, and the new Rowland Concerto integrated. All are high powered ss, and all sounded wonderful. I have looked at a lot of posts and most dealers and exhibits use powerfull ss. I have had mine for 5 years or so and prolly will keep them for a long time. On the used market they are a steal.
I run my C-8 Ltd's with Granite audio 860 mono's in triode mode. Very not flat : ) They could use some more punch and to be perfectly honest it should have more power. These are very very powerful sounding 30 watt amps as well I should mention (sound like they have more drive than the cary V12i's)
