Apos

I purchased a set of the Apos Select 12AU7s for my Conrad Johnson Preamp. What a significant difference these tubes make compared to NOS tubes. They are silent with absolutely no microphonics, and the amount of musical detail that I now get from my system is amazing. They bring out tge small musical details that I never heard before. Thanks to these tubes I have started to get reaquainted with all of my music so that I can hear what I have been missing before adding the Apos Select tubes. They are definitely as advertised.

Apos is great! Communication on product ETA, follow through and shipping all good!

Apos is a wonderful company to do business with.

Very cool sounds

Everything about my experience was great. Product was awesome and they even included a balanced cable with the IEMs I wasn't expecting. Shipping was fast and everything was just as you'd expect from a quality brand. Would buy more if they could ship more to my country.
