Lyngdorf RP-1

I needed a crossover between my Joseph Pulsars and my two Genesis/Underwood subs. After a trial, I've ended up with the Lyngdorf RP-1, which provides both a highly flexible digital crossover and RoomPerfect. The latter is a true revelation. I've been in this hobby for over 40 years now, and I'll categorically state that no change/addition - perhaps apart from a major speaker upgrade - has made such a positive difference as has the RP-1. In addition to smoothing out room modes, RoomPerfect is quite clearly having an effect far up into the midrange, and in unexpected ways. Soundstage focus is significantly improved, and I can assure you that the Pulsars are no slouches in this regard to begin with. More than anything, though, is the extremely strong sense of 'solidity' of every instrument and voice. I have a hard time putting this into words, but effectively it simply all sounds more real, more 'there'. I am currently enjoying the best sound reproduction experience I've had in my home, and it's within a hair of the best I've ever heard regardless of cost and complexity. This thing is worth every penny and more.

I am in no way associated with Lyngdorf. Just passing along the very positive experience.

I'd love to hear one of these in my system. I've got Vandersteen 5A's and have spent considerable time setting the EQ for the bass. I also have a decent amount of room treatment. I cannot imagine my system sounding much better, but I somehow think that it would.

Congrats on the purchase. I'm sure you'll get lots of enjoyment from it.

You have a very sophisticated system, including a superb analog front end. Do you feel you're losing anything, benefits aside, by adding A-D and D-A stages to the chain, not to mention the extra component and interconnects?

Curriemt11, I use the Lyngdorf DPA-1 digital preamplifier in my system and couldn't agree more. It provided a major upgrade for my system.

I also have a very good turntable and cartridge in this system and it sounds great. If I didn't tell a guest that there was A to D and D to A conversions taking place they would never guess. The Lyngdorf is very smooth and extremely detailed and musical.

Audiodude - Given the Vandy's bass EQ, I would suspect that you would hear less overall improvement than most. That's just a guess of course.

Drubin - you hit upon my greatest single fear i.e. that the digitization of my pure analog signal would be compromised. I can tell you without the slightest hesitation that I can hear no difference whatever with the Lyngdorf in or out of the system. I assure you that I spent many hours trying to do so! The purist in me actually wanted to be able to hear some degradation. I was even prepared to accept a bit of downside if the accompanying benefits were great enough. It just didn't happen. Not that I'm complaining...

Plato - I see that you had precisely the same experience. These things really need to be better known.

I had a similar experience. Although my room was not too bad, it did balance the soundstage in areas I had no idea there were a issues in.

In the end I did feel it EQ'd a tad too much bottom end out of my system at the time. The software version I had didn't let you tweak this. I think since then the software has been updated to ease that curve.

I also tried the integrated amp version but it did sound a bit sterile & lifeless.
