The room looks great by the way. He has spent some money on the room treatments and on the electronics.
We listened first to the Jubes w/o the sub first off all analog with a custom non eq passive Crossover. I was shocked at the curve of the bass bin with no EQ. It was w/o the humps seen in the typical unmodified response curve. Yes there was a small peak at 1.5 K and 10K. We only heard a few tracks with this setup.
Then switched to the digital he has described above.
This system has no preamp. From PC via USB to the hilo then to the amps. The idea of doing something like this with a DEQX in the past has been discussed here before. He considered this route before.
We switched to the digital and I was out the gate surprised with what I heard. I played mostly my late 70's funk tracks that I've listened to multiple hundreds of times. No doubt that the two tracks Con funk shun "Miss got the body" and Cameo "Keep it Hot" are the best I've heard when it comes to detail, 3D and freakin' "decay". I've never heard a system that makes the decay of instruments this noticeable. These are old recordings too. I also played tracks that had notable strengths in the 80 Hz area that I love and it reproduced those well. There are also many tracks I played that will kill my ears if the K402's aren't setup right....and it didn't do that either.
This isn't a "warm" system by any means. I've never heard that PASS Xa25 before....it is possible I'm picking up its benefits with all the detail. The sound didn't get brittle which I've heard in the past with jubes (I'm not going there so don't ask).
Bass is clean and snappy. I give him some credit, most would have the bass unnaturally turned up with this system...... I'm mean how could you not with that 1802 in your face. The bass was well integrated and just at the right strength in my tracks I played. I see no reason to stuff the jubes in the corners.
Quick summary, this system has exceptional detail, balance and decay like I've never heard before. No warmth. Some 3D. No hiss at all with an ear up to the horn. No pops or clicks. Can't hear the fan on the crown amp.
To my ears, the right channel is a tad bit hotter....but it could be my ears. In my room the stereo always seems to be hotter on my left...go figure.
I wouldn't hesitate to recommend this route of setup to anyone else if they didn't like the usual digital setup for some reason.
