Je reviens au sujet du topic: phono de Fidler,
D'ailleurs c'est un nom qui monte en UK et en USA
je vous donne cette info
Michael Fidler MC Pro
https://michaelfidler.com/products/pro/ ... ono-stage/
et pour les amants de ASR
https://michaelfidler.com/review/pdf/mcpasr.pdf
Conclusions
The MC Pro is a very accurate phono stage with very low noise and distortion. Company has full set of specifications which means great attention was paid to these
factors. I like the unique design with extra features and of course, XLR balanced output. The cost is up there for a non-high-end phono stage but I think it is justified
given the performance and features.
It is my pleasure to add the Classic Audio Michael Fidler MC Pro phonostage to my recommended list
est remplacé par Michael Fidler LO PRO
https://michaelfidler.com/products/pro/ ... ono-stage/
Available in Britain direct for £850, the LO PRO is a complete redesign of the MC PRO, bolstering performance while adding immunity to the setup issues that often plague low-output cartridges. Consequently, it offers exceptional RIAA accuracy, very low distortion, and an even higher signal-to-noise ratio than the original.
The LO PRO carries over the proven architecture of its predecessor, re-implemented with high-quality surface-mount components and several key upgrades. The new front end uses a compound loading network that reduces insertion loss while isolating the typical LOMC radio-frequency resonances that can otherwise be detected by the sensitive input transistors. The LM4562, now driving the discrete input amplifier, extends the head’s linear bandwidth and further improves immunity to RF pickup. Its increased driving ability allows a lower feedback resistance, reducing the network’s noise contribution.
Low-noise BC327 audio transistors are retained in the front end, with the parallel pairs of the MC PRO gaining an extra device per channel for further noise reduction. A quieter constant-current source replaces the previous RC rail filter. It supplies the transistors with a greater bias current, resulting in lower voltage noise and an SNR exceeding 82 dB.
