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, I have two friends with Calypso's and both (while sounding big and fun) have a pretty high noise floor, a hiss that sounds like white noise when the music is not playing. If you are used to a low noise floor like me, it might be a hard switch for you, I would not be able to get used to it. 

Hello chrissain,

     Yes, I also prefer the detail enhancing qualities of a low noise floor. Thanks for your input since a hiss would drive me crazy, too.
     Fortunately, I found a used Levinson 326S preamp for sale at a local high-end audio shop here in Indy in very good condition and at a reasonable price that’s within my budget.
     I just installed it in my system a few days ago and it’s excellent. Extremely low noise floor, neutral, accurate and very detailed overall without any trace of harshness or brightness. I’m thrilled with it and I’m really digging the sweet remote, too.

Thanks,
Tim
Have to say the ML 326S looks interesting. However, I could never use it, as my DACs all output much higher voltages than the 326S can handle unless I were to use the 0 dB gain setting. To me, at least, that seems a serious design flaw.

Currently waiting for the LA4 ordered from a local dealer, but word is that due to demand, I'll have to wait at least three weeks, maybe up to six as I'm not in the USA.

Whatever preamp one uses, I thought Benchmark's discussion of the benefits of balanced analogue connections was the most comprehensive piece on the subject I've yet seen.
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,
   Tim
