By now I suspect that you've made your decision to go w/the 300b or the 45's.
In general, what I have read in many forums and by talking to very knowledgeable people, 45s are the holy grail of the SET's.
I spent most of my audio life in SSland, until I heard tubes. My first tube amp was KT88 based, then I went to 845's because I wanted SET but my speakers were only 90 db efficient.
Yet, I still craved midrange magic and was introduced to BLHs made by johnk in this forum. Ahhh, that single driver and horn combo @ 98db efficiency is hard to beat. Yet, I wanted more and figured that the BLH speakers could deliver. johnk shared w/me that a number of his BLH users were employing Jeff Korneff's 45 SET amp with great success.
Whithout hesitation I plunged in and replaced my 845 amp with a Korneff 45 SEi integrated amp. Best audio decision I ever made. I'll put it in my will to be buried w/this amp.
Very liquid and detailed. In a word, refined. If you are looking for power, with the right speakers 2 watts can make the walls rattle. I am using mine in a room that is 20 x 30 and have more than plenty sound. Aside from the magical sound, dealing with Jeff Korneff is a distinctive pleasure. I dealt with the folks at Sofia and their practices are worlds apart.
I can't tell you how the Korneff 45 compares to the 300b since I never did that one on one comparison. All I can tell you is that you can't go wrong with the Korneff, and if you need service, your manufacturer is in Pittsburgh which is a lot closer than China.
