Hi Joe, thanks for sharing your impressions of these two fine amps. At 150 hours your Frankenstein will gain some gradual but noticeable improvement. The Takatsuki, Sophia Royal Princess are a "bit" warmer sounding and likely so is the Psvane WE Replica. I find the EML to be an excellent top to bottom tube with exceptional drive and dynamic abilities(still organic and not analytical). It plays to the strengths of the Frank's openess, tansparency and lack of colorations. Israel really likes the Psvane so it must be very good.
