I havent heard the 336 but recently had a chance to compare the 7B mono blocks to the new 14B-ST. The monos where fully worked in whereas the 14B was only a month or so old. Without a doubt the 14B had a less aggressive sound than the 7B monos. That slight edge on the midrange was gone and the top end sounded more natural. The music in general sounded more neutral and not as forward. I was impressed to say the least. Bryston may or may not be to the scale of a Levinson, but it just took a step closer with the 14B-ST especially considering the price
