    Default Power amp suggestions

    Iím building a diy hifi system and wondering what route to take with power amps. My Troels SBA MW19 monitor speakers are not particularly senesitive at 88dB at 2.8V, 1m and I have a fully balanced DCB1 pre-amp. If money were no object I'd try an EAR 861 or Glowmaster KT88, but even secondhad these are double my c. £1,500 budget. I've not found any balanced valve amps in my price bracket, either secondhand or kits. Perhaps I should shelve the tube dreams and build a Neurochrome? Any other suggestions appreciated.

    PS currently using Wyred 4 Sound SX-500 monoblocks.

    A nice Audio Innovations 500 Valve amp is very versatile and if fettled by David at AD audio this takes the amp to the next level , One was on here for sale some time ago , David re built my 500 and it sounds lovely , Can be used with 4 / 8 / and 16 ohm speakers as it has 3 sets of speaker binding posts , My one has a decent Phono stage fitted as well

    Just my opinion other will have different

    I fancy a change from class d. The W4S worked well with my Croft Epoch pre, but now I’m using a DCB1 I feel the d stands for detail ahead of deliciousness. Changing the caps in the dcb1 from Jantzen silver to Miflex kpcu has helped. But the other reason for considering a change is the rest of my system is a diy journey, from my Lenco plinth, Bigbottle MM/MC and DCB1 to the speakers, so am wondering whether to take the last step in diy too.

    Another recommendation for considering a Neurochrome kit. I am extremely happy with the 286 that I built. It's a simple build with excellent assembly instructions. Dead quiet. I hear absolutely nothing, zilch, nada when placing an ear as close as I can to some very sensitive compression drivers.

    I do though have a pair of AVI S2000MM monoblocks (that I am using at the mo) that I may part with...if the price is right....IF (and thats a big IF) you do find a pair of these, I highly recommend them!!!!!

    Hello Dominic,

    A Neurochrome could be the solid state solution but here are a couple of left-field suggestions.
    Perhaps too far out in the weeds, but worth a look over a drink or two.

    If you want to modify rather than build from scratch, I have flashbacks to an amp called a BAT VK-60.
    (BAT = Balanced Audio Technology)
    It will take no nonsense from your Troels, of that I'm confident given the spec, but caveat emptor in all other respects.

    Oooh! Check this out.

    (Nowt to do with me.)

    Perhaps a power amp with differential operation will dance with your DCB1?
