I have a Lampizator Big 7 and see no reason to change. You can pick one up for under $5k. I love how one can change the flavor by switching direct heated triodes in and out. I’ve assembled quite a collection of DHTs. Of particular note are the fabulous sounding antique triodes like the 01a, 112a and 71’s. You can pick up a pair of those for well under $100 on the auction site and they sound every bit as good as the 45, 300b, 2a3 etc. Given what I have amassed in my collection of triode tubes, including the Lampizator Edition 45 EML, which can’t be used in most other Lampizator models, I’ll be happily living with my Big 7 for quite a while. Highly recommended!
