Magnepan 1.6 is much better match with BIG TUBE AMPS like the Sonic Frontiers Power 3 which I am currently running.
The upstream source is absolutely important too.
I had tried numerous CD (YBA, Sony scd-1, Mcintosh, Esoteric, etc), DAC (Meridian, Audio research, Esoteric, Mcintosh, etc), preamplifers (YBA pre 1, McIntosh C2200, Audio research Reference 2, Conrad Johnson ACT, etc.) and power amplifier ( Pass, XA60, X250, YBA 1 & 2, McIntosh MC2301, MC250, etc)
All the above are excellent gear, yet, the only one sounds natural, real and good to my own ears are the following combination.
Tentlabs CD player, VAC preamplifier (upgraded capacitors: Mundorf Gold/Silver/Oil), Sonic Frontiers Power 3, AudioNote SET, Maggie 3.6
This combination compares to systems costing over $200,000 (Mcintosh, Sonus Fraber, Wilson Puppy, Audio research, etc)
; it just cannot compare.
I compare all the system to real, live music, and if your ears tell you to continue to listen; that is a good system.
Not listening to "Stereophile" or any person who has a "CONFLICT OF INTEREST" (they benefit from it: just like we should never listen to real estate agent, stock brokers, and especially, the lawyers; they all want nothing but your money)
Use your own ear; better yet, learn to play instrument and then you can tell which is real and which is just total horse shit.
