I’ve been deeply tracking audiophile switches for quite awhile, looking for lower cost alternatives to the Telegartner M12 switch which also requires special terminated cables. I concluded:
- Audiophile switches must be at least to the level of English Electric 8switch, and this switch is easily beaten by more expensive audiophile switches. Home improved switches like Cisco are not enough to make a noticeable sonic difference
- Unless you need a switch, this is only an option. The Sonic benefit can be minor- like upgrading a cable. Often the $3-4k+ would be better spent elsewhere
- You need a very transparent system to hear a worthwhile difference such as very low noise floor components which are costly
- Audiophile switches benefit with a better linear power supply
- Adding more switches reportedly brings sonic benefits
So for most people, it’s better to spend their money elsewhere than on an audiophile switch. YMMV
