I own a pair of special forty’s they need power to drive them. I had a 20 watt tube amplifier driving them.Then I upgrade my amplifier to a musical fidelity m6si They made those speakers sing.
Dynaudio Special 40
I have been curious about these speakers for a while when a used pair came up locally. I got them and have been more than pleased. They are amazing. They present the music in a lifelike tonally pleasing manner. Exciting without being fatiguing. Great balance and excellent bass for a bookshelf. They outperform my CSS Criton TH1=X and JBL 1600 HDI speakers which are very good in themselves.
I've been listening to them via a Unico Primo and some Schiit gear. The bass is augmented with a SCS 3000 Micro sub.
Just thought I'd share my thoughts in case someone is thinking about these speakers. The ones I got were flawless and in the red finish. Very attractive.
