BRIEF DESCRIPTION :

Valve line stage preamp remote control, SE-I/O, Bal-I/O

DESCRIPTION :

Since its introduction in 1999, the LS16 has been a best-seller, combining a relaxed, engaging musicality with good flexibility and connection options. So why change a good thing? Well, the enhancements introduced in the Mark II versions of both the Reference 2 and LS25 have proven so popular that we feel it is time to incorporate many of the same technological improvements into the LS16MKII.Functionally the LS16MKII remains unchanged except for the labeling of the inputs. (Single-ended inputs are now labeled CD, Tuner and Aux; Balanced inputs are labeled Bal 1 and Bal 2). The only other external change is the rear-panel addition of a 12V on/off trigger for remote powering of other linked audio and video components. Internally the LS16MKII closely follows the evolutionary path established by the LS25MKII - and to a great extent the Reference 2 MKII - by incorporating a JFET input stage followed by a cathode-follower/output driver stage utilizing two 6H30 twin-triodes. Now all three preamps use the same wonderful output driver tube, rated to have an estimated service life of up to 10,000 hours. Sonically the MKII is a compelling musical step forward, with greater resolution and purity. Everything sounds "faster" with less smearing. There is greater transparency, with better dynamic shading. Images are more precisely focused within an even larger and more holographic soundstage. And bass definition, control and impact are improved significantly.
