The future of preamps

Did you use your Light speed preamp with the Krells? Seems like it would be a suitable match .

No Charles. The Krells were long gone before the Lightspeed.

When it comes to impedance matching, sometimes theory <> practice. ie: On paper, McIntosh C2200 is a good match but was horrible with FBP600. No bass, highs, dynamics ... just lifeless!

I did try Lightspeed with TRL Samson monos. Samson input impedance 69K, 1M ASI Liveline IC, MW Transporter so excellent match but I didn't like the sound compare to my active.

To be fair, a MP of 60's Siemens Cca or 60's Tele e88cc in my active is more expensive but overall sound quality is more important than value to me.

@ KngHiFi, Hi, Thanks, this is good to hear some success of useing tube preamps with some of the krell amps, I did have a bad exsperience once useing a tube source direct to amp, the source, as it turned out was emitting DC into the amp, thus throwing the amp into stand-by mode, I tested the source with a volt meter, yes, there the Dc was!, I am just tring to be careful here to not damage the amp in any kind of way, I also wanted you to know, I am a big fan of useing solid state amps with tube sources or preamps, I enjoy the tube magic, brings some musicality to my ears, instead of a two dimensional over resolving sound that I find strange that alot of people like, I do understand we all have our own preferances.

@ atmasphere, Hi, what is the Tube compliment to your M-1 preamplifier?, and how many?, and is the tubes in a buffer stage?, or the out-put stage?

@Audiolabyrinth, here is a link to Atma-Sphere's MP-1 webpage. You can see that he uses 6SN7's and 12AT7's by clicking on the 'Specifications' tab.

Knghifi,
Thanks for your reply. I recalled you and Grannyring have tried the Light speed in the past.
Charles, .
