Pani,
I find it difficult to generalize due to the relatively wide range amongst products. Somec845 amps are better than others as is the case for 300b amps. Implementation seems to be the major factor in determining successful outcomes. I'm familiar with the Absolare and Viva 845 SETs and could be very happy with either. Other people have often touted the Audion Black Shadow as an excellent 845 amplifier. It's hard to avoid generalizations as we call only report what we've experienced. Pani it may be that given your speakers(and stated objectives) a PP amplifier might be what you're seeking? Your Wavac 300b is highly regarded but in your case it may not be ideal for your specific Tannoys.
