I am getting L300 LTD soon. Do you think upgrading 252S to something like 313 will make a good difference?

Doubt it, 252S is a surprisingly good amp, when fed with high quality signal.
Not a fan of L300 LTD - L300 is much more transparent and airy-sounding.

Different strokes for different folks.
The L300LE is both amazing sounding…and an amazing value

i listened to the 313 recently and it was really poor ... i don't think it is a good idea to change your 252S for it

Did STAX release another product without anyone knowing. 
It seems like the 353X is being Discontinued with a brand new;

STAXs needs better PR. They will forever stay niche if they stay secret like this.

My 6 month old SRM-353X, bought brand new (well OK, two hours use) at 40% of retail price, is going nowhere!

If STAX release their new Omega ear-speaker secretly like these two new amplifers. They truly are out of touch. 
They need better press. Not some hidden articles or magazines spread across the interwebs.

Don’t worry. They’re doing good as it is.
They know that they’re playing in a niche market.

Yeah totally agree, if Protoss is on the inside we'll could get a lot of insider information (on their uber top secret projects) and plan out our purchases better
of course get to hear about when will the new Omega would hit the market

I agree with you.
L300 LTD sounds on SRM-252S very good. Testing now.
I managed to get the adhesive plasticine (I got UHU Patafix not the Loctite Fun-Tak) to do the blu-tak MOD on my L700 Mk II. In all honesty, I have mixed feelings 'bout this hack. I tried both the full and the partial seal. The former makes the L700 very prone to "stax farts n' squeaks" whereas the latter not so much. On the plus side, it does make the bass more boomy, specially with Oratory1990's EQ settings for Equalizer APO, but it does make the vocals a bit plasticky, and quite plasticky without EQ, almost as if the singer has his/her face inside a plastic bucket. I always end up annoyed and rolling back the mod (which is easier than applying the stuff).
Most of the time I'm fine with a bit of EQ or no EQ.
Maybe it's because my DAC is an Ares II, which is R2R. It's quite a moody and sensitive DAC. Sometimes it sounds great, sometimes it's irritating and harsh. I definitely need a line conditioner, because the DAC does pick up noise rather easy (I can hear it on its PSU).
The 220 to 100V step down power transformer I use for my Stax amp might also have something to do. I actually got two of those, the one I mentioned before which has double coil, ES screen and 50W of power, while the other has a single coil and 120 watts of power. The former makes a low pitch noise, while the latter makes a high pitch noise. In both cases it's transmitted to the amp. I read somewhere that putting ferrite chokes on the power cable (from amp to transformer) can reduce line noise. Dunno how true is that. It's not like I hear buzzing or humming from the earspeakers, but a high volumes and no EQ, it sounds harsh. For some tracks I really like the raw sound that I get from no-EQ while I also appreciate the more tame and refined sound from the EQ preset.
Despite all its quirks, it's on par, if not better at times, than my Sennheiser HD800S with my tube amp.
