Elekit TU-8600 or ANK Kit 1?

Just completed my Audio Note Speaker Kit-04 build and am looking to upgrade my amp from my Bottlehead Stereomour II 2a3 SET (3.5W) and want more oomph and headroom.

Anybody have any experience, input or opinions with the above two 300B kits?

• The Elekit would be with the upgraded Lundahl TT-2770 C-Core transformers, Takman resistors, Mundorf Silver Oils and Genelax Gold Lion tube upgrade. 

• The ANK would be the Kit1-10 with C-Cores, Takmans, Mundorf Silver Oils and I believe entry level EH tubes. The ANK also would cost at least another $1,000. 

• Third option would be a Bottlehead Kaiju, however I have built many Bottlehead kits and love them, but looking to try out one of the above.

The ANK should be very synergistic with my new speakers and looks great, but a $1,000 difference (with lesser tubes) is significant.

Of course, if anyone has an Audio Note OTO SE Signature with Phono that they are looking to unload at an amazing price, feel free to pm me.
