DACs and bass response?

I'm auditioning dacs in my system. One (COS) was way to analytical, overall, but had very tight bass. Another (Aqua La Voce) is what some would describe as "musical"  and sounds  terrific in all aspects except bass. My cdp alone does better in that regard. I have monitors and no subs. Can I expect that dacs that are hyper-detailed will also offer tighter bass as a rule?

@lalitk : My source is probably the weakest link in the chain: an aging Jolida JD100 tubed cdp.  To be honest, I've been very confused by the claims and counter-claims in these forums re: the degree to which any transport feeding a dac affects the sound. I've gone back and forth between thinking I should put all my $ into a dac (which I can continue to use with a server once the Jolida breaks down), and dividing my $ between a better transport and a less expensive dac, The latter would mean allocating about $2500 per component. The Heed obelisk is one transport I've considered, as it has an internal buffer. Of course, the PS audio transports do as well. 

@worldwide wholesales: thanks for the detailed response.

@shadorne: Well, my cdp has a tubed output and I was concerned that using a separate dac and bypassing the tubes might be a problem, but so far, with the 3 dacs I've tried, it hasn't been an issue. The SS  Majestic integrated provides plenty of "tube-like" warmth. In fact, coupled with the Metrum Adagio, it seems like too much weight/thickness. I know these are not audiophile terms-- sorry for my ignorance. Darko described the Aqua La Voce as "cool" but it sounded terrific in my system, except that I found its bass response severely lacking.

Bass in general should be more articulate or nuanced with better devices.

Stuartk - I think you should address the CD transport before you get a new DAC.  The source is at least as important as the D/A, maybe more.  Before you drop $2500 on a new transport, consider a reclocker that will actually get you much lower jitter in the S/PDIF signal than a transport at a lower cost, and also provide for galvanic isolation to break ground-loops.  You can still use your existing transport. The Synchro-Mesh with Dynamo power supply and BNC reference cable combination will do this.  You could start with the Synchro-Mesh OTL and the reference BNC cable for $1100.00.  This will get you jitter in the 25psec range.

Here are some jitter plots comparing the SM to a popular transport:

As I mentioned in my first post, it has output coupling caps, that's why many owners on the net are changing that cap.
  
If that cap is too small in uF (microfarads) it will roll off the bass too early giving a shallow subdued (cool) bass, increase this cap 3 x in uF and it should fix the problem and give you a deeper stronger bass.

Or my preference is to direct couple, but you need a tech for that.
