Audio Note Power Amps

Hi guys, looking for some advice on my search for an SET amp.

I currently have a Supratek DHT pre which is connected to a First Watt SIT-2. I listen to mainly vocals, acoustics, orchestral and small ensemble kind of music. Rock, heavy metal type of music aren’t my cup of tea.

My current system sounds really good but I’m looking to add an SET power amp to my system to try a different flavour and to see whether I would like to keep the SIT-2 or the SET amp or maybe even both.

I am currently looking at the Yamamoto A-03S and some Audio Note power amps. I mentioned to a friend, who deals in high-end used equipment, that I’m looking for an Audio Note power-amp to mate with my Supratek and he straight out told me that based on his experience with a myriad of AN equipment, if I’m getting an AN power-amp then I should pair it with an AN pre or just get an AN integrated and that AN equipment doesn’t mix well with other brands.

Anyone here can advice whether the above statement hold any water? Not that I don’t believe my friend but I would like to hear from those in the community more experienced with AN equipment whether his statement is accurate in any way, which will help me decide how I proceed.

Thanks
