Pure Class A SS vs Tube Amp

@lak my only little concern about tube is maintenance and also my two channel is part of 7.2 homes theater set up    I read somewhere that tube don’t have dynamics for movies thanks and I appreciate through KLF 30 fan 
how do you compare KLF 30 with upgrade against forte 3 ?

Thanks everyone for great response 
@jyprez plinius SA is great especially option to switch to class A or AB
but I think the upgrade and also special dedicated line is little hard or who can do the upgrade for me ?

I’m very please for great response from everyone thanks appreciated 
after reading all the comments and suggestions  I have decide to separate my 2 channel from home theater  
now my new preamp Michi P5 is class A design well I don’t know much about class a preamps I just love the looks lol
I think passlab XA25 first Watts J2 Shiit Aegir and some monoblocks are in consideration I need to read more 

Thanks everyone for great recommendations
can I run tube amp with SS PREAMP?
are they going to make any difference

@almarg  thanks you’re exactly right is rated 102dB 
I will check pass lab out
my current amplifier parasound A21+ Is 300 WPC at 8 ohms first 6 watts is pure class A sounds really good I’m just wondering what I’m missing i guess I need more class A lol 

@ihcho 
i did little upgrade to it


1. Titanium tweeter diaphragms
2. A-55-G midrange drivers
3. Crites crossovers with new internal wiring
4. Ciare 12" woofers
5. Sealed cabs with PL Premium X3
6. Added front to back bracing (minimal)
7. Swapped the stock metal jumpers with 10 guage Mogami jumpers. This one surprised me.

Thanks for great response I really appreciate everyone inputs
After reading all the comments 
I narrow it down to this amps 
passlab XA25 first Watts j2 and SIT 3
too bad no balance XLR 
any passlab that has same qualities with  XLR output ?

@atmasphere 
thanks for great detail response any tube amp recommendation ?

@almarg 
thanks you’re right I google it and has XLR connection 

@charles1dad 
Raven don’t have any affordable tube amp only integrated I really want to go separates thanks I will the rest out 

Seems like with gain complications I’m still not going to get great benefits with Michi P5 and passlab first Watts J2 ?

Now I’m thinking about XA 30.8
since eventually I may move to focal Electra 1038 when my 4 months twins grow little bit 
I want separates and I really want to keep my Michi P5 Preamp gain is complicated with first Watts J2 
the question is passlab XA 30.8 is better than Parasound A21+

pm sent 

Thanks everyone for great response
I think I’m more towards passlab xa 30.8 now
I think it will work now and future speaker focal Electra upgrade with some suggestions tweaks recommended by @almarg thanks 
now I need deal or recommended dealer lol 

Special thanks to everyone for great contributions and response
