Here we have a great 1990's vintage amp from Threshold in superb cosmetic and working condition. Carried a $4,200 MSRP when released, equaling $7,000 in today's dollars. Designed by Nelson Pass, this amplifier operates in Class A providing 100W into 8 ohms. If you have a second unit you could run it mono for an astounding 350W! If you haven't tried a Class A amplifier you owe it to yourself for sure. More on this piece from Stereophile: Description & designExcept for the binding posts, which appear to be your standard-issue plastic-knob variety, the T-200 has the quality look and feel of a true high-end amplifier. Fit and finish are excellent, and the 5/8"-thick faceplate sports sculpted handles. Inputs are switch-selectable between unbalanced RCA and balanced XLR. Another switch (safety-locked) selects between stereo and mono operation. Rated at 100Wpc into 8 ohms, the T-200 can be bridged for mono operation, in which case it puts out 350W into 8 ohms. Although the amp is quite heavy, the front and rear handles make it easy to move around. SoundPerhaps it's ironic, given the difficulty I had driving the T-200 in the balanced mode, but the best word I can think of to characterize the amplifier's performance is balanced. Through changes in associated equipment and in listening to a wide range of music, I was continually struck by the T-200's ability to present music in a coherent, everything-in- proper-proportion manner. This is not to imply that the amp sounded bland or uninvolving—when the recording itself was exciting, the T-200 allowed all the excitement to come through, neither sharpening nor softening timbres or dynamic contrasts. ConclusionGiven the right associated components, the Threshold T-200 can be the centerpiece of an audio system which offers tonal neutrality, precise imaging, and lively dynamics. It gives subjectively equal weight to bass, midrange, and treble, with a high degree of transparency throughout the entire range. Its presentation is neither forward nor laid-back. Although the T-200 is outpointed in certain respects by competing products (eg, the Bryston 7Bs have even greater authority in the bass), the T-200's carefully balanced array of virtues is such that, in my opinion, it crosses the, well, threshold, to Class A.Given the right associated components, the Threshold T-200 can be the centerpiece of an audio system which offers tonal neutrality, precise imaging, and lively dynamics.
