I'm posting here after salivating for the KH120's for too long. Add me to the list who fell for the hype. The KH120 is being compared to the Adam A7X so it must be a lot better than my Adam A5X. Big mistake. I set the speakers up for critical listening. I much prefer the A5X over the KH120's with a good DAC.
The KH120 are a lot more forgiving. Give them a crappy DAC and they will sing. The A5X on the other hand sounds too warm and and too dark. Bass is like a thump. Lack of bass extension. The highs are irritating and lifeless. I have to dial the tweeter pot 2 notches down but still doesn't sound as as good as the KH120. Forget about the bass. KH120 got it regardless of which DAC.
On a good DAC, however, that's where it all ends. The KH120's do not produce clear separation between instruments. Vocals sounds like there is huge mouth 1 ft in diameter singing in front of me. The edges are muddy harsh and highs are rough to non-existent and they appear all over the place. Moving to A5X, they have very precise imaging and depth. The speakers are in a triangle position where I listen to but there is a huge orchestra 5 to 10 ft away from me. Very transparent. The highs are very sweet. With a Sub8 and crossover dialed to about 75-80Hz, the low end is not an issue. I can listen to very low volume level and the sound coming out is still very clear.
I wanted to like the KH120 since they cost me twice as much as the A5X but no matter how I set them up, I cannot make them sound as good as the A5X. I am not sure if it is because I use the Adam Sub8 on both set-ups. But even with XLR cables plugged in directly to the monitors from the DAC bypassing the sub, I still cannot get the KH120's to sound as clear.
Just for critical listening on a desktop and not mixing, the A5X got it for me. I'll set the KH120 to my bedroom 10 ft apart from each other hoping I can get clearer imaging. We'll see.
By the way, I tested the monitors using LH Labs Pulse-Infinity DAC - matched femto clocks, naked resistors, PCM and DSD256, Lightspeed split USB cable, LH Labs LPS on the DAC and sMS-200 music server, iSO-CAT6, Intona, Gotham Quad XLR's, Roon, and direct to PC running Foobar with SOtM tX-USBexp.
