s_k_77, appreciate you sharing your experience with the LTA ZOTL40 Reference with NOS Mullard tubes.
Are MULLARD NOS EL34s and LTA ZOTL40 REF worth the price of admission?
I'm considering giving an older Linear Tube Audio (LTA) ZOTL40 Ref amp an audition. LTA has a factory upgrade that includes upgrading to Mullard NOS EL34s for $800 (or less with additional discounts). I am wondering if quad set of old-stock Mullard EL34s are worth the $800 price of admission? I don't pretend to know what anyone else's budget is but $800 for quad EL34s seems like a lot. If I'm paying the premium, it better be across the board and not just improvements on chamber music or obscure Chinese opera (no offense intended). Does anyone have experience with either NOS Mullard tubes or LTA ZOTL40 Ref amp? If so, please chime in. Thanks.
