Review: Foundation Research LC-2 AC filter

Category: Accessories

My musical tastes include pop, folk, classical, instrumental, and a little bit of country. I can listen to almost any type of music provided it's recorded well.

Perhaps the most important aspects to a system for me include:
o Resolution.
o Dynamics. Giving that live bite.
o The abilitiy to reproduce the entire frequency spectrum (say 17Hz to 25kHz).
o The synergy of the system as a whole will draw the listener into the performance.

What I dislike most in a system include:
o Coloration.
o Smearing or veiling of the highs.
o Compressing the lows.
o Congesting at loud volumes and/or when playing complex music.
o A synergy that does not invite the listener into the performance.
o That cheap sounding yet very expensive 'hi-fi' sound.

The Foundation Research LC-2 and the two LC-1's have been in my system for over a year now.

The Foundation Research LC-2 replaced my Cardas Golden Reference power cable.

Substituting the Golden Reference power cable with the FR LC-2 provided the following sonic enhancements:

o A much lowered noise-floor. i.e. blacker background
o More pronounced imaging.
o Better soundstaging.
o Virtually eliminated previosly noticeable sibilance.
o And adding a FR LC-1 to my source and then another LC-1 to my pre provided even more of the same benefits.

The strengths of the LC-2 include:
o It is about the price of a decent aftermarket power cable, but has potentially far greater impact than some to many aftermarket power cables.
o The LC-2 is about half the size of a breadbox which keeps it from being too cumbersome.

The weaknesses of the LC-2 include:
o There is a box, small as it is.
o The LC-2 is rated for amplifiers at 200 wpc into 8ohm or less. Therefore, I lose just a little impact in the bass regions and in overall dynamics. But it is still well worth the compromise. Foundation Research has recently developed a new LC-3 for amplifiers that draw more current. That may very well be my next purchase.

If money were no object:
I would still own the Foudation Research LC-2 and LC-1's. At least until somebody comes up with a better alternative.

None. Although I've tried several aftermarket power cables.
Stehno: A couple of questions. Where and how are you lifting or floating the grounds in your system? And would the LC-1 be sufficient for a 75W channel integrated; is there a guage difference between LC-1 and LC-2? Thanks
Hdm, I am floating the ground for all dedicated lines back at the service panel. And an LC-1 is good for up to 100 wpc whereas the LC-2 is rated for up to 200 wpc and I believe the new LC-3 is for up to 300+ wpc.

The reviewing software did not capture the price of the LC-2 which retails for $900, the LC-1 at $695. And I believe the LC-3 retails for $1200.

These are passive in-line power conditioners and one of the benefits is that you do not use a power cable with them as the LC's come with their own power cabling. Except for the LC-3 in which you'll have to supply your own pc.

It's hard to find much info on Foundation Research products but here's a few web-sites that I am aware of that provide info and pics:

The Analog Shop's web-site has them listed under 'What's Hot'. Here they also provide their opinion on the LC's.

As to a gauge difference, I assume you mean in the electrical power cabling portion? Not from what I can tell.
