I'm. to familiar with the SR-Lambdas you've mentioned. Are these currently in production? Thanks.
Sorry to say Joseph that specific model is long gone from the new market. Of the current Stax the latest Lambda model would be the SR-507 unless they have snuck in something newer without me knowing about it. I have the one step below SR-407 Signature along with a SR-Lambda.
That said you do occasionally see the SR-Lambda for sale on the used market, usually nicely priced.
