for low volume levels I think that one or two active monitors will be more than enough..

a DT25 for always very low volume levels playing it seems a bit wasted in my opinion because the included real valves never work that way..

I'm BARELY an intermediate player, and have been through a ton of equipment while learning.

I had an HD500 that I sold and now I have another one.

I had a DT25 that I sold (even though I liked it a lot).

I have a pair of Rokit 8 monitors that I got about a week ago.

I have a pair of Sennheiser HD280 headphones.

My experience so far is that for home use only, the Rokit monitors are much better for me than the DT25 was. The DT could get LOUD and definitely sounded best that way, but that was louder than I wanted. The low volume mode was okay, but was a noticeable downgrade from normal volume mode. The Rokit 8s are very good for my use at home. They can also get very loud, but they sound just as great at low volumes as at higher ones. And stereo effects are really cool too. I will say that I'd have been just fine with the 6s.

Oh another good thing about the Rokits is that I have them connected to the HD500 and leave the 500 connected to my laptop, so I can play any audio from the laptop through the Rokits.

I've got a pair of the little Rokit 5s and I think they're excellent. I was a bit concerned about their capability at the lower end, but I was pleasantly surprised. They're set up in one of the spare bedrooms, a good distance apart for a nice stereo spread and are more than happy anywhere from the-neighbour-is-in-bed volume to the-neighbour-is-on-holiday volume.
