Interesting point, as I was hoping to read comparisons here. I know in my system my switch setup sounds amazing. But I have only compared it against three other audiophile switches all of which are cheaper, so I would hope the more expensive sound better. Although that is not always the case. Only one of the four switches I have tried is mentioned here, the Ethergen. I have the SOtM switch which sounded better in my system. Frankly a lot better, but then it is double the price.
I also tried the Electric 8 switch, sounds great, lacks bass and weight. The AQVOX SE switch. Found this a bit edgy and not as good as the Ethergen, although similar price.
Adding good external clocks lifted the performance massively.
Hope that helps a little towards comparisons.
