Are the KEF Blade/Blade 2 Metas a Significant Upgrade from Blade?

Thank you all for your most helpful comments! 
I am thoroughly enjoying my original KEF Blade 2s driven by my Coda 16.0. Can’t really justify spending the additional funds on the new Metas or the time in selling my like new originals. My 66 yo hearing, which has seen/heard better days, may or may not fully appreciate the upgrade. Still interested though!

@audiobrian What are you using along with the CODA#16? That is really a great amp. I have the CODA 07x preamp too, but I would use my Benchmark LA4 preamp with any future CODA #16. I loved the LA4 preamp + CODA #8 (now sold).

Hi yyzsantabarbara:

I have been using VAC preamplifiers for 20 years and my Signature IIa mates  beautifully with the Coda 16.0, making a great amplifier even better! I truly have no interest in trying other preamplifiers as all my VACs have mated great with SS and tube amplifiers. Highly recommend any and all models from the Renaissance V on up. All the best!

The following mono amp was one that I wanted to demo last week.

Michi M8 Monoblock Power Amplifier - The Music Room (tmraudio.com)

The Los Angeles dealer I was close by to only had the integrated amp and not the monos. The integrated amp had a Class AB sound to it and was very good. The CODA #16 and KRELL 175XD are (mostly) Class A and sound smoother. However, I am intrigued by the idea of using really massive power on the Blades.

The Mitchi monos are likely similar sounding to the Hegel H30 mono with the Mitchi 1/2 the price. I have heard the H30 with Blade 1 in an excellent room. It was rather exciting though not the most refined sound, which sometimes is not a bad thing.

I’m afraid I haven’t heard the Michi amplifiers live but I’ve heard and read many accolades. I will say that I’ve found the Coda 16 to be a very special match for my Blade 2s, refined, musical, authoritative, with as much power as my Blades will ever desire in my room. All the best!
