Douk Audio A5 Stereo Budget Amplifier Review
Kiváló termék.
Great little amplifier!
The amp is amazing. Two changes I would like to see: the glass door on top should be hinged or made of plexiglass as I successfully broke it before I ever got the amp installed. Second, clearly mark thelow filter settings to assist in dialing in the correct frequency.
This is an excellent amplifier at an unbelievable price. I would recommend it highly.
Not just great for the money! Audiophile Reference level out of the box, and once cheaply modified, beyond critique!Listen folks, I'm a nutty audiophile. I've heard and owned all sorts of amps, both tube and solid state, amps costing as much as 10k+. When I had to send an Enleum Amp23r (6.5k retail) to South Korea for servicing, based on chatter amongst respected audiophiles, I figured I'd experiment with this Douk amp. I paid my $120 for the 48v version. I also ordered Sparkos ss3602 Op Amps for $150. Before getting the op amps in, I was super impressed with the performance of the Douk, although it fell short of the best I'd owned, it was much better than most amps under 2kish in price! Mind you, I was and am still sourcing the Douk with a 5k DAC/Streamer called the Wattson Madison LE (designed and built in Switzerland). The modified Douk is totally up to the task of amplifying one of the best digital sources in the world! I've recently added a 1.5k, all analog preamp (Ladder Chopin) in front of the Douk, and that has proved a perfect match. The op-amp modified Douk is beyond critique!This is an unreal amp! It is my reference amp, and costs 1/8th the price of the speaker cables connected to it! WTF!
