Like a time capsule. Serial number 00807. 35th anniversary version, from 1995, when these were made in Japan. These highly regarded headphones are in mint condition. They have been stored in the box which has been in a plastic bag for the last decade or so. Leather and foam are in excellent condition. Considered the best of the legacy Stax Lambda headphones. Doubtful that you can find this headphone in better condition anywhere. Also have a Stax extension cord that I will sell for an additional $125. Please also see SRM-T1 tube headphone amp that is separate listing. Credit card usage pleas add 3%. Stereophile Review (1997)
"Is this the big secret you've been keeping from me?"
By my count, we've reviewed variations on the Lambda theme 10 times over the years, and each time, the reviewer decided that the basic Lambda sound—fast, detailed, uncolored, transparent, and ever so slightly etched in the upper mids—had been improved upon.
The Nova Signature is no exception. It is fast and vivid and uncolored. It sounds superbly balanced from top to bottom, and while the phones lack a sense of real wallop in the deep bass, Stax has resisted the temptation to hype bass presence.
There is still the slightest hint of roughness in the upper-mids/low-highs region, which, by itself, lends an almost pleasing touch of realism. When compared to the Stax Omega, however, this revealed itself to be a form of coloration. As good as the Nova Sigs are—and as close as they come to the Omegas, which is very close—the more expensive (and currently unavailable) headsets had an even greater sense of relaxed, natural musical detail.
But since you can't get the Omegas, I wouldn't worry about such a small difference for a minute. The Lambda Nova Signature represents a substantial improvement over the Lambda Pro Signature in every parameter and, given the current price, represents one helluva bargain as well.
