I already have a Benchmark trio in my primary listening system. After upgrading to the AHB2 in my secondary system, I quickly realized that I needed the LA4 to deliver the best analog signal to the AHB2. By doing so, I no longer have a trimmed digital signal from my decent DAC/Preamp. Now, even at my usual low-volume listening levels, my DAC delivers a full-bit digital signal to the LA4, allowing the AHB2 work it's magic at producing maximum audio clarity. Expensive for a secondary system? Yes. Worth it? Absolutely! And, based on history, I likely will eventually get a DAC3 B to complete this second Benchmark stack. Rory, the Benchmark sales manager, has given me great customer service.

The LA4 paired with the AHB2 prides excellent audio detail and clarity. Very good match with hybrid electrostatic speaker systems. The remote control is challenging for volume adjustments. Would be better if the remote control had a knob that mirrors the LA4 volume control function.

I swapped my Schiit Kara preamplifier for a Benchmark LA4. What a change. The Kara was good, but this is on another level, a huge improvement. The Benchmark LA4 is a fantastic preamplifier.
