I recently got the simaudio 330a to drive sopra no2. I also have the cxa61 and denon x3700h. I found the 330a to sound noticeably better than the power amp from the cxa61(smoother, better bass). However, I am finding that there is an audible noise floor from the midrange and tweeter of the sopra no2 when connected to the 330a(when holding my ear next to the drivers). When I connected the sopras to the x3700h, the static from the midrange vanished and the static in the tweeter became quieter. I found the static to be lower also when using cxa61 connected to the x3700h. Why is the 330a introducing a higher noise floor? It cost ~4k so I am wondering if this is due to the 330a picking up small distortions that the power amps from the cxa61 or x3700h couldn't, or if there is a problem with the amp. Does anyone here have thoughts about this? I am not sure what to think
