Review and Measurements of Benchmark HPA4 Headphone Amp/Pre


This sets up something akin to an old-school ohm power-matched system where the source component is a relatively high output, and the first output gain stage comes from the HPA4 , with the AHB2 doing less heavy-lifting. Benchmark says that setup allows for the lowest noise floor with a nearly unmeasurably low distortion.

The HPA4 is built on the idea of avoiding any sort of bit-stripping volume control in the digital realm. The volume knob is a step precision encoder, driving relays that engage resistors, in 0.

With the volume control set to maximum 0 dB attenuation , output is at unity gain to the balanced inputs. You can memory-set a gain level for each input, so for instance, if you wanted to compare an analog source to a digital transfer, you can precisely level-match. Or like I often do measure an original LP release against a digital remaster.

Maybe Benchmark can address this with a firmware update? It might be too much neutrality for pleasure listening to all music on all headphones, but this type of clarity is important for a modern mixing and mastering setup. In the audiophile world, deluxe headphone-only systems are a growth market, and top-drawer headphones are getting better and more expensive all the time.

They are different-sounding, but both represent my kind of music, and the human voice, very well. Putting it in numbers, the THX headphone amp is capable of peak-to-peak voltage swings of 25V and an output of 1. It puts out 6 watts into 16 ohms! This should give you the idea that this thing will drive any low-efficiency cans you want to plug in. For all this silence and neutrality you have to pay a pretty penny, but is it worth it? As with all pieces of your system, it depends. However, at this price level, I do wish the HPA4 had flexible output switching and level-trim memory for the outputs.

The remote might also be reworked to allow push-button output switching. When playing music you love, it will fire all the pleasure synapses. Available in black or silver: With or without remote.

Benchmark HPA4 Review – The One to rule them All!

Thank you for a detailed review. Plucked acoustic bass notes are more textured and bass timbre is more rich e. There is better soundstage depth at regular listening volumes, and cymbals have a more realistic shimmer and natural clarity. Everything is more easily discerned in the mix. In one piece of choral music I very easily clearly heard individual voices located in space without having to concentrate on listening.

Clearly Benchmark would be starting any kind of head-to-head with one hand tied behind its back.

With the boom in headphone listening outpacing even the uptake of new turntables, the hi-fi landscape has changed to a significant extent. Not only are hi-fi shows shining a spotlight on the personal listening experience but dedicated headphone events have spun out in their own right. Two of these attenuators feed the headphone outputs and two service the preamp outputs. As PM notes in his Lab Report , this design gives the HPA4 not only outstanding performance, but also rather impressive — to say the least — signal delivery, whether into headphones or external power amplification.
