A cautionary tale for those using an AHB2 who may be thinking about adding an LA4 or HPA4 - I had been looking for a preamp to move away from digital volume control and to incorporate my turntable back into my system, and naturally tried a Benchmark preamp, the LA4. Unfortunately in my system I’m noticing a big drop off in sound quality and musical enjoyment with the LA4 as opposed to digital volume control. The LA4 introduced a good deal of brightness and I notice how much smoother music sounds with digital volume control. I just bought Benchmark’s xlr cables to see if these might help resolve the issue - don’t have high hopes but it’s worth a shot before I try to return or sell. If anyone knows of a high quality solution where digital volume control can be effected through a discrete device with a volume knob and remote please let me know, I have searched but not been able to find one.
