Would you recommend the JLTi standalone or allways in the company of the external PSU ?
I have only used the JLTI without the power supply a few times. From what I remember the highs seemed to be more prominent and it sounded thinner with less weight.
It could be that changing the loading would help or depending on the rest of the system (dark sounding) it might be better.
I think you should be able to find one with the power supply used for ~$1200-1400 maybe less. Shipping a SS unit that is this small is relatively risk free and you save yourself the wear on your cartridge while burning it in.
They are not that rare just watch for one over the next few months spring is a good time to buy.
