If you buy used you get to try in your room with your system. If you don't like it you can sell used and get your money back. It's the only way short of a thirty day dealer demo.
What is the best tube pre-amp for my system
I am considering an Ayon Spheris lll to complement my Ayon CD 5, both are tube systems, powered by a Pass 350-8. Speakers are B&W 802N, not the Diamonds. Before I commit to the Ayon, I would like to hear from anyone with practical knowledge of really good tube Pre-amps
