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

Music Direct rocks, 60 day is great, but I suspect that a 2 week break-in time will be enough to make a discussion. Just plug it into an outlet and turn it on to max volume and leave the LA-4 for a few weeks. All will be will well once in I the system afterwards. 
This is not a kit that will get sweeter with time. It is ruthless, yet so revealingly. If you what some editorializing on sound, this is not your device. I find that that a truthful line amplifier will balance the front and back end brilliantly. 
I have seen that folks are comparing the LA-4 to preamplifiers in the $20,000 range, I feel that this goes way beyond that point. 
If you have a simple system, this is your go to Line Amplifier. I have no investment or prior knowledge of Benchmark (other than prior reviews of their products). This is my first experience with the company. They simply have hit a home run on a great kit. For that, I am impressed.

@fast I hated headphones since I thought they sounded awful and gave me fatigue. The HPA4 was reputed to be one of the best headphone amps in the world. So for $500 more than the LA4 I thought it would be a good idea to get the HPA4, just in case I go back to the dark side.

Now after 3 months of mostly headphone only listening I can say I was missing out by not paying attention to headphones for the past decade. Today, I use a Meze Empyprean headphone and it is incredible. Still not as great as a 2 channel but great in it’s own way. The HPA4 is an incredible value when you also consider the headphone aspect + the 2 channel. The beauty of the HPA4 is that you get a mini AHB2 inside the HPA4. You can definitely hear the silence.

Music Direct is also where I buy my next speaker, the Yamaha NS5000. It has been a pleasure dealing with them so far. The Benchmark gear will drive that speaker (using 2 AHB2's)

I am actually considering the LA4 and may sell my PS Audio BHK pre.

Going from the warm sound to no sound maybe something to see if you would like with a home trial first. What amps and source do you have?

You guys are making me very curious again about the Benchmark low distortion, low noise approach I was originally keen on trying out with one of their preamps. The approach of just getting out of the way and letting the music itself add any sweetening to the overall sound still makes a lot of intuitive sense to me. The results many of you are attaining with the Benchmark preamps just further validates my thinking.on the benefits of overall system neutrality.
I understand that my choice of the ML 326S preamp instead, which I perceive as basically very accurate and revealing but as adding just a touch of sweetness and palpability in general, may stop a few degrees short of absolute neutrality but I still continue to enjoy it very much.
Of course. without actually auditioning the Benchmark in my system I can’t be certain but I’m imagining I’m experiencing a similar level of neutrality with the ML. However, I’m thinking I’ll probably need to just try the Benchmark out to compare and know for sure which preamp I ultimately prefer.

Enjoy,
Tim
