Next upgrade for my analog source

jperry, that makes absolutely no sense. Why would a tone arm make it impossible to use a computer program? If you had a turntable with a built in phono amp with equalization you could still use Pure Vinyl to record you would just deactivate it's equalization feature. Check out Channel D's web site. The only problem I have with Pure Music which I use the most is that every two hours or so it will choke and has to be rebooted. Something to do with a memory overload with the newer apple operating systems. It is supposed to be corrected next release. 
justmetoo, just because you prefer MM cartridges does not mean everyone has to buy one. The vast majority of critical listeners with elaborate systems over the $75,000 dollar mark prefer MC cartridges. I would take any Lyra cartridge over any MM cartridge in a heartbeat and I am absolutely sure I am not alone in that sentiment. This does not include Grado and probably Soundsmith as they are moving iron cartridges. 
Jadislover, Channel D is direct purchase only. You buy it on line. The unit runs on batteries and I believe has a universal power supply for recharging which it does automatically when you turn it off. But you should check if it runs on the power you have.

@mijostyn ,

Below is an excerpt from the Stereophile review you cited:

"Being a current-mode phono preamplifier—one in which a dead short takes the place of a resistive load, and current amplification takes the place of voltage amplification—the Lino C 2.0 is intended for use only with cartridges of low output and low internal impedance—the lower impedance, the better. The closer the Lino gets to seeing a short circuit, the happier it and you will be—as long as your tonearm wiring doesn’t tie chassis common ground to the cartridge’s signal leads—which means that unless you operate on it, you can’t use your Rega tonearm with the Channel D."

I was curious about the product, read the review and noticed the caveat. No need for the OP to buy something that doesn’t work with other equipment.

Justmetoo and jperry thanks for the input!. My rega p6 tt output cables are built in (cant be replaced) and does not have a separate ground cable. Would this hinder the improvements if i go lyra delos? 
Yes my pmc has biwiring terminals and yes I am only using the base terminal, and using the jumper meta (small clyindrical bronze). Would the sound improve if i change to jumper cables?

currently im auditioning the ps audio stellar phonostage pre amp. First impression is the detail and sound stage is really good... but the sound is a bit thin compared  to my 834p. Probably needs more break in time.

@jadislover,

I owned a 834P for over a decade. It's known to have a better sounding mm stage than it's mc stage. If you go for a lomc,  you"ll need a SUT and another phono cable.

This is a tough one. All your equipment is relatively good.
Improving any one will be an incremental improvement.

Interesting that all your choices are a little on the euphonic side.
Maybe take a step with any one of these elements toward a very precise analytic side. This may add a little more resolution.

Maybe the next cartridge is a Microline?
Maybe the next turntable is a direct drive?
Maybe the next phonostage is solid state?
