220 vs 440
#1
Apologies if this has been discussed before, I searched the forum but could not find anything on the topic.

I'm pondering adding a second 220PRO CI to my existing 220PRO CI to upgrade to a 440PRO. Is this a profound upgrade in terms of additional control over the speakers as well as sound quality? It will be appreciated if forumites who have gone this route could share some thoughts. 

By the way, I've recently upgraded my Vivid Audio B1's to the B1 Decades.

I added a companion, back in the days of the Expert 200, making mine a 400. I noticed subtle improvements in bass and treble definition, improvements in soundstaging width and depth and an overall feeling of a more powerful sound (not surprisingly). I don’t think you’d regret the move to dual mono.
Edit: plus you’ve also got more inputs/outputs should you need them.

Axel  has put it quite scincingly.  Thats exactly what I experienced moving from 220 - dual 220's.

Thank you Axel.  Well put.

There are several posts from a while back talking about upgrading from the 200 to 400, which are probably worth taking a look at.  These include:

I'm wondering if it would be possible to convert a single 220 to a mono 440? Meaning that one makes a normal 440 config for dual mono, but then just uses one amp?

This could be a way for 220 owners to test with mono recordings (and one speaker) if there's any difference compared to one channel of a stereo 220, and if the upgrade is worth it.

There are plenty of threads around here about missing right side channels on dual mono setups so I am sure a single mono amp will work. It’s a very different thing to listen to one speaker instead of two though. It will take your brain some time to adjust.

Indeed mono recordings sound quite different with one speaker vs. two. But maybe it would be a way to extrapolate so that if the difference is readily apparent on just one speaker, then it probably would be that also on a proper dual mono 440 setup. Might experiment with it myself Smile

So I managed to source another 220 PRO CI at a decent price and spend the afternoon setting it up.
All I can say is WOW.
I thought that the improvements would be subtle, but they are far more than that.
The soundstage has doubled in size both wide and deep. Bass is better controlled and snappier and extra detail shine through at lower volume.
The sound is also just that little bit sweeter to my ears.

Worth it? ...., indeed.

That's the extra power doing its thing.
