I’ve been offered a deal on a secondhand pair Focal Solo6 ST6’s for less than the price of the KH120ii.
Am feeling quite torn as to which option to go for!?
I just went through the same decision. I ended up buying the Focals, from Sweetwater for about $1100 each. I like them and I've decided to keep them, but I'll probably always wonder how the KH120ii would sound in comparison in my room.
Here's my main reasons for choosing the Focals. I was upgrading from Focal Alpha 65s, which I had for 8 years without issues. My listening position is 9 feet from the speakers. which may be a stretch for the KH120s, but then again, probably not, because this is in my study and I'm not listening at high SPL.
I use DSP. I previously used REW. Now I use Focus Fidelity, which is easier for me and I like the results. The DSP convolution files are loaded into Roon, which is my only source. Without DSP, in my room, I can hear the brightness Amir measured in the 3-8khz range. With DSP, I can adjust that to my taste, and I think it sounds really good. In this room, I think I'm getting mostly direct sound, with some reflections. I've compared DSP full frequency, vs DSP below 500hz, vs no DSP, and I prefer the DSP full frequency in this room. In a different system, in my high-ceiling, highly reflective living room, I prefer DSP below 500hz only. All this is to say, if you're not going to use DSP, the Focals may not be the best choice, depending on your room and listening position.
I use a RSL subwoofer, crossed at 60hz. I have the Focals' HPF at 45hz. The HPF is nice to have to integrate a sub. I'm still measuring and experimenting with different settings. I knew I wouldn't invest in the KH subwoofer or use their DSP, so those features, while great, wouldn't benefit me.
The Focals are connected to a Sabaj DAC via balanced cables. Using balanced cables they turn on almost instantly on receiving a signal. Not much delay at all.
They're not Class D and the rear panel gets warm, but not hot. My Alpha 65s were the same way and ran 8 years without a hitch, so I decided not to worry about that.
I like the way the Focals look, although I wasn't sure I would.
If you get them, use good stands. I bought a set from Monoprice which are just right.
