Levinson, Pass labs or Parasound?

There is an auction for a Symphonic line RG-1 at $800 with no reserve. I have owned 2 of these. They are OUTSTANDING amplifiers. Period. Smooth, quick, and exceptional control over drivers. IMHO leaps and bounds over the 3 you mention. 100W class A is not as "tiny" as it sounds. These amps will put out at least 65 amps of current. Mine produced almost 70 amps. i actually heard two of these with A-1's and it was a knockout! I did not like the Halo with them although a Simaudio W5 stereo sounded very good.

Thanks for all the responses. I have heard good things about the nuforce line. I am in the states and might have to set aside some time with them. I was afraid the Levinsons @ 250/channel might not be up to the task but they are a quality piece so I thought i would ask. Any other amp suggestions would be appreciated used in the 3 to 4K ball park.

If you are looking for an amplifier that has enough power and will perform exceptionally well with the Soundlab's for around $4,500 used, then you owe it to yourself to audition a pair of Bryston 7B-SST monoblock amplifiers. I used to own Pass Labs X-600 monos, which cost over twice as much, and the Bryston amps were a definite improvement in my system. Plus, they come with a 20 year warranty which doesn't hurt down the road if you want to trade up again.

if you're considering Pass Labs amplifier, then you're probably better off if you get the latest .5 amps.
X350.5 or even X250.5. Although I never compared how the older series amps sound vs the newer x.5 series, word is the newer ones are more natural sounding. I own X250.5 and it is a great amplifier. Drives my B&Ws no problems.
In the under $4k range, used, also consider McCormack DNA-500.

Hi Brimac. Jason at NuForce does not recommend plugging their amps into power conditioners. I'm delighted to hear that the PS Audio 300 power plant is compatible with them. What else is plugged into the PS Audio PP?
