Audio Logic v. Audio Note v. Audio Aero v. Audiome


I have been reading the great comments about the Audio Logic DAC. Have any of you have compared it to any of the DACs or one-box units from the above manufacturers?

My system consists of:
Cary 308-T CDP
First Sound Pres. Deluxe MKII Preamp
VTL MB -450 Sig. amps
Merlin Milennium speakers
the Bobby P. recommended Cardas Golden Ref. interconnects and speake wire
Various power cords

I find that complex, dynamic music gets congested. Bass is a bit muddy. And, on faster music, it seems that my combo. of equipment has trouble keeping up.

My hope is that an improved source will address some of these issues.

Any thoughts are greatly appreciated. Thanks.

Make sure you are putting some Siemen cca in that dac, make a whole world different, had tried telefunken cca, amperex, mullard, in my system the siemen sound best.
Goone, thanks. I wouldn't started with those if you hadn't suggested them. I will start looking for a pair. I tried to find some for my preamp several months ago and couldn't find a pair. Do you happen to know anyone who might have some?
Brooksl, there is one pair on sale but kind expensive try him I had extra pair but want to hold on to them a little bit, also have you roll any tube in your vtl amp like input, driver or output I also had the vtl.
Goone, are you referring to Scubadaddy? I have some cryoed Telefunken 12AT7s in my VTLs. They are great. Have you tried replacing the 6350s? Any improvement? Thanks.
