It is doable to get decent starter kit for this type of money if you are looking to go second hand! Few weeks ago I've been seeling my backup kit and I've made a £200 bundle consisting of MS10i speakers, Pioneer 333 amp, denon DCD435 CD player and Dual 415 Turntable. This might not be the high end but it's a great startup kit. So my point, if you are willing to spent some time on gumtree looking for decent second hand kit than £400 can get you really nice starter setup! So if you want a recomendation of the second hand kit you can get some nice amps going reasonably cheap on gumtre, check 930ax/bx, nad 320bee, nad 3020, pioneer a400, denon pma 250 or 350 etc. they should be sold there for aruound £50-£100Speakers wise check: MS10i/MS20i (preferebly pearl edition), bower wilkins 600/601, Wharfedale Diamonds 8.1/9.1/10.1, Q accoustic speakers etc. most of the stuff can be bought for 50-100£Turntable wise, well you have plenty to choose from, you can go with new project turntale, or again you can get some decent second hand TT. For 200£ I've seen some technics 1210TT this is easy to use, great sounding TT. There is plenty of others but once again this would require spending some time on gumtree
. Good luck with assembling your kit m8!
