I too quite enjoy the HE500 and LF339 combo as if heard it numerous times but o dont know it seems it didn't click with me, but since i am changing my DAC soon too i might give it a go.
Ultimately i would like that romantic vibe that the LF339 & HD650 produces, but with a wider soundstage faster pace and sparkly treble. Thanks for the help mate

That sentence basically describes how I viewed the LF339 and HE-500 pairing. What are the tubes that you are using with the LF339? Personally, I found the Tung-Sol 5998 + RCA 5693 pairing to be what you described, with a slightly shelved treble.
The 6AS7G + EF80 combination, which is also fantastic, seemed to have a more impactful bass, better music separation for micro-detail, and sparkly treble (Which made it a better pairing in most instances), but I felt like I could just sit without a specific playlist on, with my music set to shuffle on my entire library with the combination prior to this one. It all comes down to preference, mood, and the type of listening that you'll be doing really (Analytical versus Relaxed). Most of the time, technically better does not mean preferentially better, and that's why most people end up buying and selling so much equipment (myself included), then buying back stuff we previously owned.
Also, what DAC are you currently using? I found that neutral DACs (Such as the V800) don't pair as greatly with the LF339. I much prefer the widely cheaper HRT MSII+ pairing with the La Figaro 339, as it just seems to be more musical (probably due to its warm, grainy nature) and synergizes better.
The best I have ever heard the HE-500 has been on the V200 + V800 with Balanced inputs and single ended output, but then it really sounds a lot more like the HE-6 driven by a powerful speaker amp... Which doesn't sound like what you're looking for.
