I’m about to push the button to get 2 SVS 3000 micros to add to ATC SCM40s.

Congrats!  I’m sure you’re gonna be thrilled.  Please follow up with impressions if you could.  BTW, SVS has excellent customer service so you might want to describe your room to them and they’ll probably cut down your tinker time considerably with some helpful tips — that’s what I’d do.  Once you get them dialed in let your wife listen to a good recording and while it’s playing turn the subs off and look at her reaction.  She might end up really loving those small boxes.  And if she cuts you some slack with this audio silliness I’d say you got a good one and a keeper.  Love your speakers BTW.  Are they version 1 or 2, and what amp are you driving them with?

Version two. I’ve got an older Musical Fidelity a 308 integrated amp, and recently introduced a Moon Mind 2 streamer and a Denifrips Pontus 2. I think the subs will finish things off for me, but you never know when a future audio itch needs scratching, do you?

Anyway, having started modestly just a few years ago, I think I have great-sounding compatible components now.

Excellent stuff, and I totally agree the subs will bring you to a level you never knew was there — probably about the best absolute upgrade you could make.  Of course, there’s always power conditioning, power cables, interconnects, digital and erhernet IC, room treatments, etc.  It never ends, but I have a feeling you know that and should’ve never said anything will “finish things off” for you.  Silly person.  All you did was upset the audio Gods who will now strike down on you with furious anger and take even more $$$ from you.  Deep down you know I’m right. 

Oh my God, I guess the audio gods take their cue from the golf gods. I had no idea.

 I am now saying quite loudly that I will never finish off my system and I will always want to buy more and more and more and more. What I need to do is to develop an allergy to cables and room treatments. 

SVS doesn’t get enough love in the audiophile world.  Nice choice of subs. I use two SB1000 Pros and like that they can do both low level or high level connections.  I also really like that you can dial them in from the listening seat via the app.  I’m sure I’ll swap them out at some point for REL just to see if they live up to the hype, but the SVS sound great in my system.
