has anyone had any problems w/ Jasmine phono LP2.0



One of either channels stops working.
I have already returned the unit back to China twice
They have replaced the unit and now it's gone down for the third time. I contacted a local tech in NYC and was advised
it probably would not be worth having the unit repaired.
Has anyone else had this problem? Can anyone recommend a tech
here in the states preferably in the New York area

Hi Redglobe, I don't believe any producer will save on such
small value capacitors (1uF). But I am tempted to exchange
those thin copper wire to the connectors for the silver
wire. Have enyone looked inside the pre?
Deed anyone try MM input for the MC carts? The amplifiaction of the MM input is such (71dB?) that I was able to use MC carts with 0.3 mV output with no problem at all.
I thought I had (left channel not working) and also posted
the pre back to China and got a new one while still keeping
the old one. But the fault was in my tonearm wiring. I am very
glad with this phono-pre which I use in my second
system mostly to test carts. In this system I use the FR-64
with removable headshell so very easy to change carts.
Check first your amp., then phono-cable , then the tonearm
wire and the cart. With a simple Voltmeter you can check
all the wire. My problem was the left channel tonearm
wire which was sometime on and sometime off ( loose contact).
Redglove, I assume that designers listen to different capacitors before they decide which to use. Then I also assume that capacitors of such small value are not so
expensive such that saving on them is an issue. It would be strange if the amateurs like we are can improve whatever design by changing two capacitors. But I know
that 'believing' is a strong feeling.
Dear Lew, that's a bit thick. Redglobe mentioned $25 for
two while the manufacturers pay much less . Besides the
technical guys speak about 'capacitors mythology'. I
hope some of them will shine in.
Now this may be called 'Lew's paradox': in this contribution you suggest some correlation between the price and the quality of a component while elwehre you
deny such a correlation ( Eppo, Magic diamond ,etc).
Rockinrony, 'I could go on but I think I have made my point.' Really? 'Better parts' imply comparison between at least some of them. You should first try and compare, say, 10 different caps and than make your 'point'. Otherwise the 'point' must be made by someone else who actually made some comparison such that you can copy his 'point'
regarding the question which of the compared caps is 'better' than the other. You may have 'a point' with such a strategy but such 'point' is not considered as 'the point'. The 'technical part' in the vocabulary of the amateurs is 'cheap caps' versus 'expensive caps'. 10 x 2 expensive caps = ý. It may than be the case that one is 'better' off with an (much
more) expensive pre with 'better parts' already soldered in by the electronic engineer who designed the pre.
I myself am from the other 'school'. The 'wire school'. Those wire in the Jasmine are not to my liking. They look cheap to me and are very thin.My 'point' is to substitute
those with very expensive 99,999 silver wire. The added 'point' is that all my interconnects, phono-cable included, are also 'pure silver' kind. This way my 'treasure' will become the real treasury.

Dear Redglobe, 'Your horse' decided to drink the water. So your effort was not wasted. For the European members I can
say that those Jantzen Superior Z-caps are easy to get for
about 25 euro, postage included. I order them in Germany. The original caps are MKT kind and about 17x12x7mm 'large'. The Jantzen are ,say, 10x
larger so to fit them in place one need to use the caps wire as fastening device. After fastening and soldering simple cut superfluous wire. The caps will hang in air but
need to be lower than the electrolictic caps near them.
I also exchanged the output wire for my own solid wire which is an alloy of gold and silver. The same wire is use
in my interconnect to the amp. My original intention was to
also exchange the input wire but the risk to damage those very thin wire inside the Jasmine induced me to leave those 'as is'. The comfort being : those are so short it
may not matter...
Well first of all I was happy to hear that my Jasmin was
functioning after my soldering. Then I was surprised to hear 'some other' phono-pre. This upgrade is unbelievable. The dynamic range is much more extended, the sound is without any sharpness while the harmonics in the conjuction with the keynots are one 'wholeness'. I was very sceptical about the improvement the caps can provide but in this case I am convinced. But, alas, I can't say what the contribution of my own wire is. Those who want to try the same upgrade will nee to first exchange the caps
then listen and then exchange the wire.
Hi Truenai...(what a name), I am continously messing with different carts of both kinds. In some sense it was inevitable to forget to switch from MM to MC input or the other way round. That is how I discovered that the MM input has sufficient amplification for some MC carts. But my highest MC carts output is 0,5 mV (Ortofon MC 25FL). My discovery was of the 'optical nature' and not acoustical one. I am not sure what this imply for my hearing capabilities but my surprise was of, say, the 'general nature'.

Redglobe, My dear comrade Don bought the new Jasmine with the double phono input. When I consulted the Einstein designer about one added phono-input he refused resolute to make one for me. According to him this will harm the sound.I then decided to buy the Basis Exclusive with two separate and mutual independent phono-pres. I use two tonearms on my Kuzma and was very reluctant to use just one input for both arms. I advised my comrade Don to change the caps for the Jantzen superior but also to change the inside wire for the same kind he uses in his tonearm and IC to the amp. That is what I deed in my 'old Jasmine'. The caps exchange was easilly done but he was not able to change the wire because the new Jasmine has much more complex wiring than the old one. From both 'facts' I deduce that the old Jasmine is a better proposition assuming the caps exchange.
