Amplifier Upgrade Decision

Would like to add that working with Mark at Reno Hi-Fi is a great experience.  Along with many other fine dealers I've worked with, Mark is just a pleasure to deal with.  Highly recommended!

@markmendenhall  Hows your system doing? Any changes?

Since 2017?  Replaced my SF Oly 3's with Manger P1 passives; replaced the Hegel CDP with a Marantz SA-10, added a JL Audio e110 subwoofer, moved up the Shunyata line with newer model interconnects and speaker cables, added a Schitt tone control unit, still running the X250.8 and the First Sound pre with dual power supplies; Nottingham Ace Spacedeck, 10" Ace Anna tonearm with Kiseki NS Purpleheart cartridge. Pretty much done now; $ spent at this point in the hobby is going towards rounding out and adding to our music collection.  

@markmendenhalI,
The components that you added are all very good in my opinion and I am sure that you are very happy with this set of upgraded components.
I didn't go for a new amplifier in 2017 because of some other priorities but I have made some significant changes this year to my 2 channel audio system. First I got a Bricasti DAC/Source controller M12 to replace Oppo UDP-205 which replaced Oppo BDP- 95 a year or two back. This also replaced Parasound pre-amplifier Halo JC2 BP.
Then I added a Bricasti amplifier M25 (Dual Mono design) to replace Parasound Halo A21+.
I have auditioned following three amplifiers when selecting the Bricasti unit.
1. Gato PWR-222 mono blocks 
2. Parasound  Halo JC1+ mono blocks 
3. Luxman M900u 
I found the Bricasti unit to be the fastest, clean and detailed compared to the above list of amplifiers and the combination Bricasti M12 and M25 was the smoothest.
Now I am looking out for a good power conditioner for my system. I would also be putting up following components for sale shortly 
1. Oppo BDP- 95
2. Parasound - Halo JC2 BP
3. Parasound - Halo A21+
4. Nordost Heimdall 2 Speaker cable 2M
There is another thing I wanted to mention here. Very recently I tried out a speaker cable and a Digital- Coaxial cable (Signature Series) from the Canadian company Audio Sensibility and very pleasantly surprised with its performance. I had initially very low expectation of this Audio Sensibility cables, specifically the speaker cable. But when I compared it with my Nordost Heimdall 2 speaker cable I found it to be significantly outperforming the Nordost cable. So much so I am selling the Nordost speaker cable. The Audio Sensibility digital cable is also very good. I am going to try their Power cable and Interconnect cable down the line and compare it against Nordost Heimdall 2 and Frey 2 cables. 
Thanks

To the OP congrats on your updated system! I've heard the Bricasti gear at Cap Audiofest the last couple years driving Tidal speakers and sounding excellent.
