I have demoed a V40SE in my home - owned a V70SE and just recently upgraded to the V110. A very good friend of mine owns a V80. They are all great integrateds. Soft start extends the tube life and they all have protection against output tube arc over that is second to none IMO. I have had several tubes arc over in the last few years. I do a lot of tube rolling. The only downside there is the input and driver tubes are recessed and hard to swap without removing the cover. Cover removal is easy with the V70/80/110 but difficult on the V40. Don't let the power specs deter you. There is very little difference between all 4. I personally think the V70SE is the best bang for the $$. They all will give a little more control in the sound as you move up the ladder. You can also add the black box or super black box depending on your current speakers. The black box adds 4X the capacitance to the Octave where the super black box adds 10x. So since you have monitors like me the super black box is overkill.
