I need a preamp to record mainly vocals, nylon string guitar, trumpet and flute and to a lesser extent didgeridoo amd percussion. From what I have been able to find through research and my money constraints these preamps, DBX 786, ISA 428, AMek Pure path, are to my liking. Eventually I wanna record drums so I will be definitely be getting teh ISA 428 with digital option at some stage. Right now I just want a decent preamp, two would be better, with a nice clean sound but some little nuances so that I can pull out some nice tones. The DBX looks to be my favoured choice. But if the ISA is as good as the DBX or AMek I may as well get that now. Any form of advice with regards to this and any other preamp would be much appreciated. I don't really want a tube preamp so I would preferably like responses regarding transformer based preamps.
