notable consolidation possibility, should I or not?

I am considering to take on a pretty good sized consolidation in my main 2 channel system that I use for both music and AV. Here is what I currently have:

• Audio Refinement separates (Pre5, Multi5 using 2 channels)
• modified Rega RP6 with AT-33PTG/II low MC using Jasmine LP2 mkII phono stage
• Cambridge DacMagic for AV signal and streaming via smart TV optical out
• ProAc studio 148s

I am considering consolidating the pre, the amp, the dac and the phono stage into a Simaudio 340i X (with dac, phono and balanced input cards). I did find a local Seattle area dealer where I can demo a 340i X but in order to get it in house vs my current setup, I need to purchase it and I only have a 7 day evaluation window for a full refund. Also, this dealer (Definitive Audio in Bellevue and Seattle) said they cannot list Simaudio on their available products page but really didn’t go into detail why, does anyone know why this would be? I really like the warmth and detail of the Audio Refinement / YBA signature which continues through with the Jasmine phono stage sound signature also. My current dac is decent and have no complaints about it.

What does everyone think of this consolidation? Will the 340i better the AR and phono stage separates plus still continue to deliver the warmth and detail I look for in a system? I have read that many like the warmth of the 340i but some have also said it can get edgy and fatiguing. My ProAcs can do that with certain source or equipment, so I have to be careful here. I’ve also read the 340i like their other integrated amps and phono stages are very quiet (I tried an I-3 in my system when the AR gear was getting serviced and it did not better my separates but it had no equipment noise and presented a very black background). The last thing I am concerned about is that the 340i does not have a tape or processor loop for any kind of tone adjustment via EQ or other options. I know their highest integrated option does but this is out of my price range.

Appreciate everyone’s thoughts and input in advance.
