Update:  I no longer sell Jasmine.  If you have a phono stage you wish to have repaired or modified, please contact me.  To purchase, I suggest eBay, or Carl at www.Canadianhifi.com

Many thanks to those who’ve purchased products in the past!

Jasmine LP2.0mkII Phono Preamplifier

Jasmine-logo

The Jasmine Audio LP2.0mkII was designed with high-end analog users in mind.   The LP2.0mkII features a detachable power supply for isolating the hum of transformer and noise of the rectifiers from the signal PCB.   The Class-A, single-ended circuitry uses passive RC RIAA equalization and does not use “active” or negative-feedback equalization.  Several overlapping layers of mixed materials are used to isolate the circuitry from electromagnetic and radio-frequency interference.  These features and benefits are unique for such a modestly priced unit.  The LP2.0mkII challenges the limits of high-performance vinyl replay at this price point.

Priced fairly, at only $575.00 when purchasing on our eBay store, you can purchase here for $550, a $25 savings over purchasing on eBay (ask about other discounts).  All LP2.0 units are sold.  The factory has not produced this model in several years.

  • Independent Power Supplies
  • Multiple layers of mixed materials, featuring thick gauge steel and aluminum, used for EMI and RFI isolation, and mechanical damping.
  • Precision hand-matched J-FET 2SK170, selected for linearity, are used for low-noise (over 90% are rejected).
  • Single-ended, class-A, zero negative feedback (passive) topology ensures wide frequency response and excellent dynamic range.

    When it comes to longevity, reliability and ease of repair, you can rest easy.   All the parts are easy to get, though your local Radio Shack would have to special order a few of them.  For instance, the low voltage polypropylene coupling capacitors are available through all audiophile parts dealers (Parts Connexion, Michael Percy, etc..), and could be changed for super-high-priced boutique parts from Mundorf (just for an example).  The low voltage polypropylene capacitor is probably the least likely part to fail in the entire unit.  Polypropylene capacitors are self-healing, and the voltage ratings of these capacitors allow a very large safety margin.  As power supply electrolytic capacitors age (15-20 years), they start to lose their effectiveness.  After repairing and modifying audio electronics for years, electrolytic capacitors are the most likely parts to fail, in all classes of electronics, other than vacuum tubes.  The capacitors used by Jasmine are all normal electrolytic capacitor values, available through every electronics parts dealer in the world. The rectifiers and regulator chips are also standard parts.  The only part that would take a few days to acquire would be the 2SK170 transistors, which aren’t stocked by the big parts suppliers like Mouser and Digikey. The units are easy to work on, and I can maintain them for customers. Any competent tech can work on these (they are simple analog circuits–no proprietary chip sets or digital circuits are involved).  Because they are simple, with 3 transistors in the gain path, reliability is very good.
