Is there a Solid State amp that can satisfy a SET guy?

Only Robert Koda Takumi K-160 can beat just about any tube amps in existence.

Perhaps with time invested in Pass Labs XA-25, First Watt SIT-3 you would come to see their beautiful strengths like I have experienced. That said, I love BOTH worlds so I have a Luxman switcher for when I want this or that... 

Well, now I have been enjoying my Atma-Sphere M-60s for a few months. They are destination amps. Right away, I deeply knew that I would never go back to SETs! The Atmas have the sweet, natural sound of SET 300bs with the detail of a great SS amp.
The SET was wonderful but it really had a warm and lovely sound that covered up much of the music. I love the metaphor of the “ Sonics screwdriver loosening the sound”. Yes, I do miss the beautiful tone of the SET but any day would choose the accuracy of the Atmas.
Interesting that I grabbed a Bakoon HA-01 headphone amp from US Audio Mart for $725. (kind of happy that they seem to now be a formidable competitor to Audiogon) It should come next week.
Very curious to hear how it compares to my current HA, David Berning’s prototype of his great MICROZOTL. I believe the Bakoon will be a different kind of sound. Seems it may be a new take on SS performance. I will have it on trial. Let’s see if I keep it.

Mike, obviously we are in agreement on the M-60's.  They are also my destination amps.  I have no interest in looking elsewhere.  I also agree that when everything else is right, or close to it, the M-60's deliver the best of all worlds.  Sweetness, resolution, and enough power to drive most reasonably efficient speakers that are north of 8 Ohms.  It is all there.   It was a bit different for me however, in that they revealed some rather serious issues with my room and other pieces in my system.  It took not a small effort for me to get everything else dialed in.   That would be a caution I would issue to any one trying these amps.   Others probably won't know right away, as you did, what these amps could deliver. 

Good for you enjoying the M-60s. I have the MA-1s, excellent amps, if you use a DHT preamp with the M-60s these are so transparent that you will get the DHT lush sound, such sound although amazing is not my cup of tea for every day listening, I rather have a pre with 6SN7s, but that is just my preference.Congrats on the OTLs, it is hard to go back to SET or SS from there.
