Not for this amp, I will wait until i hear an SMPSU built amp to my liking first..

I dislike CD , so to like one is rare .
The lack of deeper understanding, and "measurementitus" still afflicts the CD area -- the good news is that seemingly a few more manufacturers are starting to get it, I was impressed at the recent hifi show that a number of stock machines were doing very nicely: CH Precision made particularly accurate noises ...

I still have an LP12 . It is a lot better than most other decks with 1W motors . I recently had an email about Lenco 75's . I suspect in many ways the 75 is better than a Linn . The pick up arm not as bad as it looks , however not to the standard of the deck . My criticism is the 75 has about 70% the torque it ideally needs ( still more than a Linn ) . My suggestion was a wild one . Add an external belt drive . If done with care all sorts of possibilities become viable . One includes slightly dropping the voltage to the main motor so as to have less rumble . The drive systems would need to be harmonized . Knowing how these things work I doubt it would be too difficult . In view of the need for synchronicity I probably would use a synchronous motor and raw mains electricity . OK I dislike synchronous motors and belts . It this case I can only see good coming from their use . I think John Curl said something about this before , someone tried to tell him Lenco better than Linn .

My first awakening to the Lenco was a lady who lived in Parktown Oxford . I had always been intrigued by the houses and the install was a chance to see inside ( fabulous ) . She had me bring a very nice hi fi with a $600 CD player ( Arcam ) . The payment was on the understanding that the Lenco would not be put to shame . The Lenco p-ssed on the CD player . She had worked on ship's most of her life and loved musicals . Turns out her neighbours in the USA were the real family from the Sound of Music . Apparently living up to the image of the film wasn't easy . We spent all night playing her records . I had thought her very posh and unapproachable ,how wrong I was . She bought records when ever should could , never having much chance to play them . It was much more important than I could ever have guessed that it worked . If I miss those days it would be installing equipment . It was a bit like going on stage , you never knew exactly how well it would go .

If someone writes a year from now saying Lenco destroys most belt drives regardless of price remember who told you . Are Lenco's as good as Garrard's ? Strangely , no they are not . If the two companies had worked together who knows how good it could have been ? Lenco did little things nicer than they needed to . Things you saw were awful ( the head-shell ) . So sad . MZ motorcycles were the same ( East Germany ) , didn't stop them winning the ISDT nearly every year . Didn't stop Susuki steeling their designer .

Yeah took me a while to tame the switching hash and embrace SMPSUs, no going back now. You could try the chipamp on my blog as first proof of concept.

The Lenco is like that lump they use in the Dodge Viper . The LP12 is way outside of it's design brief and well done Linn . The Lenco is just a lump of cheap metal . What I always forget is I know more about this than I realize . Damp the platter but not with pure rubber . Get torque right . Cut corner off of Lenco chassis so as to connect the arm with the baseboard rather than the metal . Float the structure ( that's my way = easier ) . Finesse the bearing . Clean the power in . Listen to the music .

The old Renault Dauville ( ? ) engine was used for family cars . It also could give 2100 BHP for qualifying and <1000 BHP race day in the turbo days ( JPS = 2100 , would last 6 laps I am told . Information from interpreting speed traps and extrapolating , officially 750 BHP ) . Renault went around scrap yards it is said to get them . The family use and aging helped the metal much like cryogenics do today . Garrard platters also were aged in the rain for 7 months . The were machined then rested then machined again . It cost just a bit of storage . 301's were built in the summer to avoid sending staff home . Realistic pricing would say Garrard gave them away . The Lenco is your Dauville .



We costed redoing the 301 in China . Minimum $ 400 000 . Doubtless double when we got through to them that it looks the same doesn't make it the same . It would cost even allowing for the cheap production $1000 a unit . Guess what ? I wouldn't want one .
