Looking for 300B SET (one output tube per channel) to pair with Shindo masseto pre amp. How would you compare Wavac EC300B, Shindo WE300B, Yamamoto A-09S and Verdier 300B?

I read all of these above opinions and they are so funny ...thank god im 63 spent over 300k on audio and realize there is no minimizing the importance of.....good ears and experience 
oh BTW if any of you think that a 300b can touch a great 6c33c pair of monoblocks your just kidding yourself 
nothing can touch a LAMM or the quicksilver triode 6c33c at an price on any speaker period my personal fav is the QS Triode 6c 33c with horns or with anything else 50 watts of PERFECTION there are no weaknesses in these monoblocks THEY ARE THE WORLDS MOST PERFECT AMPS
