Yes, without a doubt top notch mod with the best parts available. But the base form of Leak 20 is relatively the same, as long as the transformers are all in good condition. Those standard Leaks are the ones I want and can afford. Modding is part of the fun, subject to the availability of funds and parts. Speaking about parts, any Jensen 32+32uF or 47+47uF you want to sell? I missed out getting them while I was hifi hibernating and Jensen is no more
