Well, after an all day affair of putting the HPA4 in and running source direct repeatedly. The HPA4 is going back to Benchmark.
I'm very sad to say the HPA4 Preamp does rob me of some upper frequency sparkle and transient response. I've run through putting the hpa4 in and taking it out several times and running each DAC direct to either my Nord Monoblocks or my Art Audio Diavolo SET Tube 300b Amplifier to my Tekton Design Encores speakers and regardless of the DAC or amps I'm using I can hear clearly a noticeable drop in resolution, upper midrange clarity, and transient response. Plucks of guitars seem a little lifeless now. The overall sound is more homogeneous sounding and more 2 dimensional sounding. It's a warmer less neutral sound, but almost like a film coating painted on everything I hear. This is really disappointing because this preamp was supposed to take my system to the next level, but unfortunately it's a step backwards for me. I'm returning it to Benchmark, but I really feel bad about it all the same.
