Should I try separates
Currently using an Exposure 2010s integrated amp with Harbeth mini monitors. Always been tempted to give separates a try. Have absolutely no complaints about my current setup just wondering if I can better my amp with separates, preferably tube pre and solid state amp on a limited budget of 1500. Also have a pair of Omega 6 Alnicos from another system that I no longer use due financial constants . Some equipment will have to go to try this endeavor. Is it worth my time to pusue this. Only will they if I can get suggestions that will better what I have . Thanks
