Some love for the Benchmark HPA4/LA4

Making this thread to show my love for this amazing preamp. Yea, all the use usual descriptions apply. Yadda yadda it is great.

It is 1:15 AM  in the morning and my kid and wife are asleep. I am not cranking it but listening at very very low volume (I have great headphones available but it sounds amazing on the speakers right now).  It is the preamp that is doing the great sound at low volume. I won't get into details., but damn this is something special. I am on my 4 or 5th scotch but do let that cloud your perception of what I am saying. I knows what I am talking about.

You guys going direct to amp from DAC. Put this into the circuit (for $2500) and tell me it is not better.

I’ve not seen or heard one yet but definitely a product of interest to me.

Currently running Audio Research sp16 preamp in one system and a Bel Canto c5i integrated in another. Noise is not an issue in either case.

I have the HPA4 and love it. I’ve bought many high end preamps over the years. Most of the big names and I spent well over $20K on a couple of them but I’m convinced that the HPA4 is the best I’ve ever heard.

I’m running a full Benchmark system with Revel speakers at the moment. The DAC3B is a reference in recording studios for a reason. I enjoy it’s neutral reproduction. The HPA4 is like a straight wire into the ABH2 amp. I ran a single ABH2 for a few weeks. It is an outstanding amp but I bought a second one and a pair in mono takes the sound to a new level.

If I want color I have that option in speaker and amps that I can switch in and out. I haven’t been doing that since I bought the Benchmark system because it’s just that good.

Nice.  Love the HPA4. What headphones are you using with the HPA4?

In my situation John Siau (the Benchmark designer) has indicated speakers like my recently purchased Thiel CS3.7 don't work with mono AHB2 but they do with a single AHB2. I am running with a single AHB2. I am keeping it but I also want to get an amp with more power in the 2 Ohm region for the CS3.7's.

yyz, I have always followed your posts, and am surprised you wound up purchasing Thiel CS3.7s ( not judging, if you enjoy them ). I go dac direct ( through a top model Luminous Audio passive unit ), and my system needs zero additional gain, and has plenty of it. I was part of an organized cable shootout several months ago, and the equipment used was all Benchmark. What I came away with, and many others concurred with my findings, was the total neutrality of the Benchmark gear.......no color of any kind, no editorializing of any kind, just what was on the recordings. Enjoy, be well and stay safe. Always, MrD.

@yyzsantabarbara I have Sennheiser HD800s and Focal Utopia HPs. Two very different HPs and they both sound great with the HPA4.

I'm curious what about the Thiels creates a problem for the ABH2 running in mono ?

That's why they're a reference in music and TV production studios. It's a great way to listen. I change out my Revels to PMC studio monitors for some of the work I do. If I want a warm and engaging movie sound I pull in a pair of Vandersteens. Having a neutral DAC/Pre/Power system really allows you to hear what each speaker's sound.
