The Merlin's are a pretty easy speaker to drive. I don't see why 30 watts wouldn't work. I believe the ARS integrated amp Bobby P. recommended was about 30 watts or so too.
Berning ZH230 amp
Has anyone had a chance to listen to the new Berning ZH230? The ZH270 garnered a lot of respect and was considered a bargain for the price. Sadly, it is no longer being made, instead we now have the ZH230. 30 watts instead of 70 and twice the price. Is it still a great deal? Would the ZH230 work with a speaker like the Merlin VSM as well as the more powerful ZH270 does?
