Benchmark LA4 Preamp?


I’m seriously considering buying this $2,500 solid-state preamp and looking for input from anyone who owns or has heard this preamp.  The LA4 is identical to their HPA4 unit just without the headphone amp.

From all the reviews and Benchmark’s site that I’ve read, this seems like an extremely low noise and neutral preamp that may be a very good match for my extremely low noise, neutral and high powered class D D-Sonic M3-600-M monoblock amps that I use to drive a pair of Magnepan 2.7QR 4 ohm speakers.
My main source for 2-ch music is a Lumin D2 dac/streamer for music files and Tidal streaming. For HT, I’ll be using a yet to be determined 4K Bluray player as I’m also transforming from an Oppo 105 1080p player and 1080p hdtv to 4K. The LA4 has caught my attention since it has dual balanced XLR inputs to accommodate the XLR outputs of the Lumin D2 and whatever new Bluray player I choose. I plan on ordering the optional remote for the LA4 which would allow easy selection between music or HT as well as being a low noise, low distortion and neutral conduit for both.

I really appreciate any input on the LA4, or even options for a high quality Bluray player with balanced outputs, that you’re able to offer.

Thanks,
Tim

Hello dr_joe,

     I was very close to ordering the Benchmark LA4. I think you’ll probably really enjoy it and I still think it’d work well in my system. About 6 months ago, when I was looking at preamps to replace my Parasound Halo P6, my goal was to try a very neutral and accurate preamp to go with my very neutral and accurate D-Sonic M3-600-M class D mono-block amps.
     But I happened to stop by a local audio/video shop here in Indy one Saturday and listened to the ML5805 integrated amp driving a pair of Magico and then a pair of Sonus Faber speakers on a customer demo. I really enjoyed the sonic qualities and extremely solid and stable imaging I heard that I mainly attributed to the Lumin D2 dac and ML integrated amp, which created the best sound stage illusion I’d ever experienced. The overall sound was very neutral, accurate and detailed but also had just a touch of euphonic sweetness that I really liked.
     This caused me to rethink my preferences and system goals. I thought I wanted absolute neutrality with nothing added or subtracted from the music. I reasoned that any euphonic sweetness should be the result of the music and not imparted by any playback equipment. I still believe in this concept in theory but felt that ML equipment was reproducing music in such a beautiful and natural manner, along with creating such an amazingly realistic 3D sound stage imaging, that I became concerned about whether the LA4, being extremely neutral in character, would be able to match the sound qualities I experienced through the ML gear.
     Long story somewhat short, I decided to buy a used ML 326S preamp for about $5K, knowing the ML 5805 integrated was basically a 326S preamp section combined with a ML class AB amp in a single integrated box, hoping to infuse my system with the same sonic qualities.
     Fortunately, this strategy worked like a charm and I’ve been enjoying music played back on my system more than ever. Just to play it safe, I also bought a new Lumin D2 dac/streamer along with the preowned 326S preamp from this dealer.

Best wishes,

Abery, just spent some time trying to find the Benchmark review you refer to, both online and in my hard copy magazines.  No luck. Would appreciate more information...issue number and page if possible.  Thanks. 
The new Absolute Sound with the Benchmark review just arrived. It’s a brief review with a full review promised in a future issue.  It’s one of the most positive reviews I’ve ever read anywhere ...even taking into account that most AS reviews are pretty positive.  
The Benchmark HPA4 (same as the LA4 + headphone amp) is the best audio piece I have ever owned. Just love it.

BTW - Does the new Absolute Sound have a review of the Yamaha NS5000? I do not see it online. For my System #2, I am going to be hooking up an all Benchmark system with the NS5000. AHB2 x 2 + HPA4 + DAC3B + Benchmark XLR + Benchmark speaker cable. Neutrality is what I want in this system. I just got the AHB2 (being shipped) and it is going to be great with the HPA4. Just need to buy the NS5000 now.
