Theta Enterprise or Ayre V1x with Vandy 5A

Thank you. I'm listening with the Ayre V5x and it is truly outstanding, but I'm just finding it a little lean in the midbass. I was hoping the V-1x might improve upon that one shortcoming as it has a much beefier power supply. At the V-1X's price however, the Theta Enterprise now enters the picture.

I suggest you try different cables before you try a different amp. You might find that a different cable gets rid of your lean mid-bass problem.

I've been running a V-5x for 1.5 yrs. w/VR4 GenIII's & there is no lack of any bass/midbass. When I switched from a Pass to an ARC pre, the bass was even better, although I recall some PC's that choked the bass (along with the soundstage).

I would suggest the standard drill here-spkr. placement, check your AC, clean connections, etc. before swapping out gear.

From what I have heard, I would tend to agreee with both driver and rex. I had not heard the V5x to be at all lean in midbass. I would double-check speaker setup, cables, and room treatments before I moved on...

You might want to check the following things on V5s for mid-bass issues:

(a) High Pass Filter Dip-Switch Settings - need to make sure you are changing this as you try different amps as it affects mid-bass directly (be sure to adjust if amp specs given for Single-ended and you are using balanced cables)

(b) If you are already adjusting this and are still lean in the mid-bass, you may want to try a setting one step down from the suggested setting for your amp's input impedance

To increase mid-bass you can also try the following in terms of speaker positioning:
(c) Can bring speakers slightly closer together, try in 1/2" increments for each speaker

(d) Can move speakers slightly closer to wall behind them in 1/2" increments

(e) Can increase toe-in slightly in 1/8" increments (measured to side wall from speaker corners)

(f) Can put "disks" or "pucks" under the spikes if you have a suspended floor (wood) in your listening room

Good Luck!
