I have been happy with my SPE 1.3. Most important to me was the ability to
use my 10W K3s or my KX3 to get full output if desired (I never felt the
need use it at 1.3KW on air).
I usually run it at 500-1000W output happily. The multiple antenna/radio
ports are a plus.
It is definitely noisier
Me, too. Long live the KPA500 ;)

Hi Dave
I had an SPE 1.5KFA for a few months.
I have also owned a KPA500 for around 4 or 5 years.
Despite the publicity blurb that says the SPE QSK is silent, it isn't. The
relay is quite noisy - at least if you are used to the totally silent
KPA500.
It is also difficult to control power wise.

The SPE 1.5 uses a single LDMOS device. While it can produce 1500W
with sufficient drive, it starts to compress well before the 1000 W
level. SPE's own
I have the 1.5K-FA. I like it. I am not heavily into contesting and I'm not
a competitive DXer.
Yes, it's less expensive than the KPA1500. It also doesn't integrate as
well with the K3. It doesn't control the K3's output power when switching
between standby and operate. One needs to remember
Well you have an Italian amp with one man US support. That one man appears to
be at least in his 80s. In my world (broadcast) many of us avoid Italian
products. YMMV and you get what you pay for.

The one piece 10kg lightweight design and a multi-voltage power supply make
the SPE 1.5k-fa very nice for travel. I do not recall reading what
transistor(s) it uses or know how loud it is or what the IMD is. The
Elecraft KPA-1500 is pretty heavy-duty and of course well supported in the
U.S.

- The KPA1500 has a separate power supply that can be located under the desk.
- KPA1500 has Ethernet remote capability.

I’m trying to decide on a SS amp. I already have the KPA500 and love it but the
price for the KPA1500 is a bit above my budget. I am looking at the SPE 1.5K-FA
which is about $1000 less. I like the fact that it has inputs for two radios
and 4 antenna connections. Plus the power supply is built
