New member here to the forum. I have been doing a ton of reading online about amps, preamps, and dacs . I just purchased a new pair of Dynaudio speakers and i am currently using a Denon AVR with preouts connected to a QSC GX5 power amp. These speakers are awesome and my next move is figuring out where to go next. Do i get a pre, a DAC, or power amps? I am thinking of upgrading the amps first and after doing some research i think i have it narrowed to either the Benchmark AHB2 (possibly 2 for mono), the PS audio BHK 300 and the PS M700 mono’s. Has anyone heard any of these amps with my speakers and if so i would love to hear your thoughts. I know these amps are all at different price points but i want to keep them a very long time. Another consideration is those that have the BHK 300’s how much has your electric bill gone up per month with these amps as i know the class D 700’s and the AHB2 Amps will be much more energy friendly or at least should be so i would love to know how much on average a month it costs to run these. I am pretty new to the hifi game so i am looking for all the recommendations and help i can get.
