Thanks for all your good information. I will take a wait and listen longer approach before I start to mix and match.
Tube recomendations for a newbie
I have just purchased a Mingda Mei Xing tube intergrated amplifier. I live in Shanghai, China. I'm new to tubes and the amp is supplied with Chinese tubes. I'm wondering if swapping tubes on this amp will provide better sound quality? If so, any recommendations? I believe the tube configuration is: EL34 x4(JJ)、12AU7 x2、12AX7 x2. The system will play mostly jazz, classical, reggae. Speakers are Wharfedale evolution 2 bookshelf speakers. Thanks...
