My question: Would you buy it or would you wait for Power Genius XL?
Anyone knows Power Genius price would be?
Anyone knows about waiting list for it?
I just dont want to be regret in future

First I love my 2K-FA and would have purchase the 1.3 if it had been out at the time, however I am not sure why you are buying another amp. To go from 500W to 1000W you will get 3dB or 1/2 of a s-unit; barely perceivable at the other end. I am not sure if others will agree but I would not buy the new amp and work on my antenna system. You will get more out of improving an antenna system than the small increase in micro volts at the other end.
Capable of legal limit (probably stretching the limit of acceptable IMD, however) but seems happier at 1KW. If you sustain legal limit for more than about 10 seconds continuous it will drop back to "mid." power level. However it works pretty well. This doesn't mean SSB or CW, but continuous modes like RTTY. RTTY you may have to drop back the power for continuous operation but this is more a thermal limitation than anything. I keep it at 1-1.2kw with no problems. And at 1kw I am plenty loud, beating out even some of the m/m big guns in pileups. Also, on RTTY it is actually better duty cycle than the 2K-FA which seems counterintuitive, but it seems to be many people's experience. The LDMOS is more modern technology than the 2K's conventional MRF151G mosfets. I have run a RTTY contest with it at 1.2kw without issue but I can't really run long transmissions. I expect power genius XL to be better in this regard. CW and SSB no problem. Power Genius XL has two devices in it so it can run better IMD and probably run cooler too, along with basically loafing at legal limit.
The 1.3K has SO2R but it is not "full" SO2R out of the box. You have to either use relays, or use a dedicated RX antenna, which actually is not a problem for me. SPE is going to introduce an additional switching unit for "full" SO2R. Power Genius XL has full SO2R meaning it can switch two inputs to two outputs seamlessly.
The 1.3K's price is actually not all that bad. I bought mine from a non-US dealer so I got a good deal due to the stronger USD plus mine doesn't have the 15dB gain limit due to the silly, outdated FCC gain rule. The drawback is that the foreign dealer has to do the warranty work so I pay shipping if it has a problem but so far so good. No price has been announced for Power Genius XL but I expect it to be priced higher.
It has a 4 port antenna switch built in which is actually a pretty good feature to have. Power Genius XL doesn't have that, and they instead direct you to buy the antenna genius switches separately. Not sure if I think this is bad or good, but I like the fact that I can switch 4 antennas out of the box.
It has the ATU option, and I have that in mine. However it is a very limited ATU. Think of the ATU your rig has built in. It can barely handle 3:1 SWR. It won't handle a wet shoelace in a tree. At that point I'd be looking for an external ATU anyway. Power Genius XL has no ATU but instead folds back power like what your transceiver does. It's not necessary to protect the finals because LDMOS devices are extremely rugged but it is necessary to protect the output filters and other components.
The fans are small and can be loud but I have heard louder tube amps on the bands, some guys sound like they are in a wind tunnel. I don't really hear it with my headphones on.
The 1.3K-FA is amazingly portable. 22lbs and even comes with a carrying case that can fit in carry on luggage on most aircraft. So it's the perfect DXpedition amp. FT4JA used a few of them. I believe TU5MH is using them now.
The 1.3K has two CAT interfaces and a control interface, and you need some cables to get it to work. Power Genius XL works with ethernet for just one cable. I like this a lot. It interfaces seamlessly with SmartSDR, which is a plus. The 1.3K-FA integrates with DDUtil and has its own control software which works ok. But I'd rather have the SmartSDR integration and ethernet.
So my advice is this - if money is no object, and you want legal limit RTTY and other high duty cycle modes and don't mind not having an ATU or built in antenna switch, go for the Power Genius XL. The comment about the price is based on speculation since they cannot offer an uncertified amp for sale. Since you are getting it without the ATU, I would wait until Flex announces pricing. They probably will have that by Dayton, after FCC approval.
If you want an amp now, and think the Power Genius XL is going to be out of your price range, and you want the antenna switch and option for an internal ATU, go with the SPE 1.3K-FA.
I'm your fan .....Didn't I tell you ?
Thank you very much for your really objetive comment.....I really appreciate your time and your courtesy to share your knowledge and experience...thank you
How do you handle your 1.3KFA, do you use DDutil or did you connect it directly to Flex?
I don't do RTTY....even I guess, dont recall how to do it hahaha....but I do a lot of JT65....hardly I use 20-30 watts...so that issue dont bother me.....
4 antennas or just one?.....sadly my condo just let me to have 2....one for VHF & UHF....and one for HF...it's Vertical Hustler 6BTV which now will be subtitude by my new SteppIR 2 elements.....so guess its not a deal breaker...
I requested 1.3KFa without ATU....my reasons were same as you told handle 3:1 SWR its not a big deal...and with a SteppIR..I won ́t need..
about money...I wonder if is better to spend it ....buying a PowerGenius or...buying an Expert and taking the change to upgrade my 6300 to 6500... What do you think?...
what I really like from PowerGenius is one cable to connect to Flex.....
Ria Thank you again

I have an Expert 2K-FA with my SteppIR
You are correct in that you do not need an ATU - most of the time - with a SteppIR
I say most of the time.. because on some bands the SWR on the SteppIR can be higher than 1:1 and it you are a purist like me you want a perfect match all the time.
The 1.3K is really a 1KW Amp with little or no headroom to get to 1.5KW and the 2K is a 2K AMP with plenty of headroom to get to 2K - my will run key down at 2330W all day long.
The Power Genius uses 2 more modern 1.5KW transistors so it has HUGE headroom above 1.5KW.
it should also have much better IMD characteristics than the Experts..BUT no one has measured them yet.
I also understand that the Power Genius will have circuitry to enable Adaptive Predistortion to greatly improve IMD products.
My 2K-FA has 4 Antenna Ports.. Very Useful ( SteppIR, Dummy Load, 160M, Multi-band Dipole for Diversity) whereas the Power Genius would require me to get an external antenna Switch
Perhaps the best thing about the Power Genius will be the fact that it is totally Ethernet controlled rather than the old style Serial Controls / USB controls....
if anything, this may be my main reason for switch to the Power Genius.
If budget doesn't allow both, pick up the ready to go SPE 1.3K and revisit gear selection after the Genius has been out for a while.
If value and overall expense is important consider a used SPE 1K, as they are very good value.
On the SPE if you think you might ever upgrade it might be wise to purchase with the internal ATU for resale purposes as well as additional utility.
(I have an Alpha 9500 at each QTH with an Alpha 78 and an SPE 1K backup. My intention is to bring a Genius into each QTH when available. YMMV of course!)
