The acquisition of an Aracam Alpha one amplifier has completely transformed my old hifi. My kit consists of a Marantz CD-63, Mission 31i speakers on sand-filled Atacama Nexus 6 stands, Nordost Flatline Gold (biwired) cables, Chord Company Chrysalis interconnect. My room is approx 6mx4m and I listen to a wide variety of music. I have got the upgrade bug (again) but have not been intensely interested in what's happening in the market for several years and am a bit out of touch (having young kids and all that!). I would genuinely appreciate some advice regarding further upgrades on a limited budget of a couple of hundred quid. I'm pretty happy with the Marantz CD source to be honest, but suspect that my speakers could be improved (the Arcam totally blows away my old Marantz PM 44 SE amp, and is far more revealing). I'm really tempted to buy a pair of used Mission 751's....but then again, the Monitor Audio Bronze Reference BR2's sound amazing...or should I buy a new interconnect (Chord Company Cobra???). I love my Nordost cables and prefer them over my Chord Company Carnival Silver's, so don't really want to change my speaker cables. Any ideas welcome. Ta in advance...
