One DAC to Rule it All

No. Any proof for you is in the listening.

This isn't a simple cable swap. It would mean a lot of rewiring to go back and fourth. I was hoping there would be a consensus as to which way would be better.

The double digital conversion would bug the crap outta me.  How are the reviews of using the DBX as a DAC?  I’d think the OKTO would be the better of the two, but that’s just an uninformed guess.  One thing I’d do is take the DBX out of the system and integrate the subs the old fashioned way and see what you get.  This would take some work obviously, but the prospect of getting a digital crossover out of the signal chain would be well worth it IMHO.  FWIW.

I had been doing it the "old fashioned" way until I got the DBX. I found a great improvement upon sending only 100 Hz and up (48db/oct.) to my main speakers (Reference 3A NEFES II), and just below 100 Hz to the subs (same slope). I wasn't expecting such an improvement in detail, but I must confess it was there. I'm just wondering about the double digital conversion. I truly believe the OKTO to be the better DAC, but it won't do the crossover and other things like parametric EQ. So, it's either both, or just the DBX doing it all.

What is your budget ? My brother has the new DCS Rossini $35k 

land incredible ,but he says he may want their master oversampler 

which mo way I would spend more then a nice car on digital or anything 

my end game dac-preamp is the T+A 200 dac it is only $7200 minus discounts 

that’s one I am saving for ,and a new car. My wife thinks $1k power cord is nuts .

I have been comparing a bunch in our audio get together for digital 

the AQ Tornado -sourse is Very good and just brings the best out of your digital .

In my 2 nd system the Eversolo DMP-A8 is a excellent dac -streamer or under $2k built with judt top quality brand parts and latest AKM 4499EX dacs and matching receiver ,and gen 3 Xmas , the interface app is Excellent ,and is even a SS server up to 4 T , imo Best Buy out there. and with any decent upgrade power cord very good sounding , Anthony Perrotta Consultants , He. gives very good package deals $$ and great service.I will give a rundown on it after full runin ,my friend owns the 6 master edition , which is good but different chipset using Sabre , the top A8 has a true active resistive ladder to relay preamp ,not a digital preamp ishocking all thst for under $2k ,I have a separate freya+ pre with good NOS tubes  which is better but on its own no loss of resolution ,Anyway I just thought I would mention it.
