Cary slp-98p tube phono tube recommendations?


Hi every one I am looking to upgrade my tubes for my new Cary Audio slp-98p with phono.
I had just replaced the 12AX7 to JJ electrics from the original chines brand. Which the JJ's sound nice but lack the low end bass I think. Would a matched set of gold lion 12AX7 ann 12AU7 be a good choice for the phono preamp tubes, and my new ortofon bronze 2m.  
let me Know your thoughts and recommendations.

You've asked this question before, if you search the forum there are a lot of recommendations.
I think the Russian version of the Gold Lion (there's also a "licensed" Chinese version I haven't heard) 12AX7s are a bargain…nice tight sound and reliability, seemingly flawless build quality.
