I think this system sounds profoundly beautiful at times but I confess I have few systems to compare it to. The SET amp seems to match well with the efficient single driver speakers. The Ah! Njoe Tjoeb with upsampling board may perhaps be called legendary for it's price. The soundstage depth and detail, the musical presence - it's all very enjoyable. Every little tweak seems to add small but welcome improvements. I think until I graduate get my Masters and start earning some money I can be happy with this system. Any suggestions for improvements would be very welcome. I'm thinking of getting a second Zen and having mono-block setup to see how that sounds. Maybe a zero autoformer to tweak with the impedance matching.Thanks for reading.
