Calling all owners - Jasmine LP 2.0 MKII

I've got about 4 full day's use on mine but do not like what I hear.

Question: How dramatically does this phono preamp change throughout break-in?

I hear distortion (spittiness and splashy bass as if it is running out of power) and a flat soundstage.

I am using the stock power cord and umbilical.

I compared it to my other three phono preamps - Hagerman Bugle, V-LPS, Biotronics Control Systems Gestalt (outstanding and extremely rare). They all are much clearer and cleaner.

It must be mentioned that I requested the Ebay seller to provide a reduction in global gain since I have loads of it with my Project Sunrise II headphone amp. They added a switch on the rear that cuts gain by about 5 dB.

well I use a Shelter 501 mk II with a origin live silver tone arm on a nice origin live Calypso tt on a Ginkgo cloud. and yes after 40 years I got the vta thing figured out. Man the cloud made more difference then the Jasmine has so far. So I am to believe from your comments this phono sings right out of the box and no break in time is required? the phono's sound does not improve much after a certain period of time break in time? just replace the coupling caps to improve the sound?

Oh! ok Thanks,
Audiogabby
The sound will change dramatically with time. I left mine on for over two months straight after purchase. After more than 50 hrs of playing time, I noticed a huge difference
cool well thats what I was thinking (hoping,praying lol)
I will let you all know my thoughts in about 2 months. Then I will compare the Jasmine to the Lehman black cube.
after that get some superior z's crossing my fingers peace out, Ron

Another consideration on output caps: An Audiogon member told me that Auricaps were even better than the Jantzen Superior Z-caps. He thought the z-caps were only just good. If that is true, the Auricaps must be really remarkable.

If you give them a try, I would like to hear of your experience.

How does on break in a new phono stage as quickly as possible besides leaving it on? I assume trying to play as much vinyl through it in the waking hours. Is there a quicker way?

I use a hagerman Inverse RIAA Filter( $50) and plug a Squeezebox Touch output in and play Internet radio none stop to accelerate the burn in.

I modded mine with Jantzen Superior z caps and a few other caps, power supply cap changed too & Shinkoh tantalum resistor. I only use the MM stage with external SUT ( AT-700 or Uesugi Ubros 5 L) and it is very good this way.
