@highend64 if you buy/use one of these 30 year old amps, the main power caps and bits regularly get replaced as others have mentioned. Has to do with age, not the condition of the amp alone. Check with different techs in your area, best of luck.
Threshold Stasis S/150
I am considering purchasing the S/150 to drive the Vandersteen 2ci. Do you think the S/150 is enough to drive the 2ci? What I have heard is that the first 30 watts is in Class A mode. Thanks

@highend64 not validated, worth re-checking, have these notes on the Vandersteen 2CI Spec: ¾ inch aluminum dome tweeter, 4 ½ “ plastic cone midrange, 8” cone woofer, and a 10” active cone radiator that handles frequencies below 35 Hz. Fequency response is 28 Hz - 20.125 kHz at + or - 3db. Its impedance is at 7 ohms nominal and 5 ohms minimum, efficiency 88db for 1 watt at one meter. ---------------------------------------------------------------------- AMP: Threshold alternative, Forte’ 1a, or Forte’ Model 3, upgraded and converted: My Pass/Forte’ Model amp is recently reconfigured to Forte’ 1a, pure Class A 50 watts now. Voltage down, bias up. Has four new 30kuf big power caps, large Torroid transformer, new bridge rectifiers, Cardas binding posts, spade connectors removed. All soldered. Not lean at all, very musical, more grunt, 47c, runs Warm at heat sinks. It’s a giant killer now. Will drive your 2ci, no issues, all goodness :)

Tend to agree, argh. Had a Parasound A23+ for 45 days myself. Bought it 2nd hand from a chap who owned it a year. Plenty broken in. Was gonna use it as a backup amp. Ended up reselling it to a new owner who was okay with it. Nice build quality, nothing special about the sound in my system, just barely okay, unfortunately. Hopefully others have better luck with this unit, maybe so. Comparing the two in my system, it’s not even close when talking upgraded/updated Class A Threshold, Forte Audio, to that particular Parasound unit. Quite a startling difference fwiw. |
