@ Charles1dad & mac48025,
I truly appreciate your feedback on the LTA MZ2-S and the CSL comparison. I have the CSL and the Melody P2688 (also based on the 101D tube) on my want list. I was hoping the MZ2-S would equal or better the CSL so that I can save some money. I guess if one has a small budget, the MZ2-S is no brainer, however, if one wants something higher, the CSL should be considered. The Lyngdorf TDAI-2170 has also piqued my interest and I have to find a way to audition one.
Thank you.
