Just bought the Mccormack DNA 0.5, after ALOT of research. Thank you all who helped me choose. Anyway, my second step on the upgrade now will be to buy a pre-amplifier. I have some cheap options available, but I want something that will make me satisfied for years to come, so research, again is necessary. My "easy" options are: Mccormack TLC-1 ($500) - Same brand, some say it'd be a good match, some say it's passive and has got no personality. I heard it myself and liked it, but no pre-outs, meaning I'd not be able to plug my Rel Strata II subwoofer in it. No remote either. Carver C-4000 ($200) - Legendary choice, don't know much about it, except it's a classic. QED Vector Reference ($600) - Another passive unit, at least this one gives me a remote. Basically I need something that will make my sound better, or at least not change it. And then some pre-outs would be good, Remote is a plus only. Price tag can't surpass $900, and territorial limitations should be respected, as I live in Brazil and cannot get certain brands. Any of you has a suggestion?
