The first impression was an increase in clarity and low level information. The proverbial lifting of veils happened producing images more three dimensional and lifelike.
The first thing you notice with the ARCHs is a big improvement to overall transparency and clarity. That alone is worth the price of admission. I also heard an expanded soundstage, improved imaging, incredible separation/layering, and a blacker background.
Everything I had enjoyed up to the insertion of the mini-ARCHs was now elevated. Individual instruments and voices in the music were easier to follow, existed in their own space and had improved tonal characteristics. This translates into better attach and more natural, extended decay (for example the strike of a cymbal and its shimmering tone as it fades off). Bass notes have better tone and are much clearer.
These days, more than ever, I look for a price-to-performance ratio that makes sense for this economically challenging time, and the ARCHs fit right in with my philosophy […] Using ARCHs designed for components, speakers, and cables allowed my system to sing at a higher level when they were used collectively vs. individually.
This room tuning kit is a must for anyone wanting to really hear their systems. The differences were enormous and well worth the money.
