The biggest reason for my selection of the X200 is the versatility of this integrated. The ability to use as a power or pr-amp with the Direct in switch for both balanced and unbalanced inputs. So if get the need for SS I can pull my Simaudio A330's out and run them as mono blocks or run my 390 as a preamp streamer.
As an Integrated the X200 is black I mean silent as silent as my 600v2.
The X200 can be used as a separate preamplifier, as an integrated power amplifier, as a stand-alone power amplifier with direct inputs, or as a headphone amplifier, but other configurations are possible.
The low noise analog front-end is built around a wideband and transparent circuit and features a phono preamp with enhanced precision too. Line level and subwoofer outputs are an absolute necessity in this category, and these ports are included on the back.
I am a big analog guy and these features really appealed to me.
We've
added a real specialty too: a built-in, studio grade Parallel
Equalizer. This kind of tools is primarily used as a master channel
effect in recording studios, to bring fresh air into the mix, as a
finishing touch. We've found that this effect can also be a huge help at
home as well, as it can breath new life into certain, not so vivid
records.
The specs allowed the wider selection of speakers also. I have Sonus faber Olympica Nova 3, Raven CeLest, Klipsch Hersey IV and others that I swap in and out of my system.
