Any comments on DAC directly to Power amp with no
08-20-15: HgeifmanMy plan is:1) Plug the Bricasti M1 DAC using balanced XLR cables into the balanced inputs on the 590ax. This means the 590ax is operating an integrated amplifier including its pre-amplifier. The Bricasti M1 will only operate as a... 
Any comments on DAC directly to Power amp with no
08-18-15: HgeifmanI am concerned about having a fully balanced DAC running into a fully balanced amplifier and NOT take advantage of the two balanced units. My test should help me decide how to proceed.Although the L-590AX is described in various ... 
A-B testing of cables
Hi Steve,Agreed for the most part, and the experience described in your second from last paragraph makes a lot of sense. However, a current will indeed flow in the return conductor of an unbalanced line-level interconnect, that is equal to the cur... 
Transport signal thru mult cables simultaneously?
A further thought that occurs to me regarding digital cable break-in: Since S/PDIF and AES/EBU cables will be terminated in nominal impedances of 75 ohms and 110 ohms, respectively, while line-level analog interconnects will generally be terminate... 
A-B testing of cables
Steve (Williewonka), re the blog post you referenced, keep in mind (as I'm sure you realize) that for current to flow a complete circuit has to be present, from source to destination and back to source.When the output of one component provides a s... 
Transport signal thru mult cables simultaneously?
KN, no, I really don't have any particular thoughts about the importance of break-in for digital cables. I'll say, though, that I would not consider anecdotal reports of such experiences to be definitive unless they involved direct comparison on t... 
Metrum Pavane NOS DAC
A correction to my previous post. When I said:Maximum speed, btw, looks like it is not much faster than redbook, as the digital data is described as being clocked into a 24 bit register serially at 35 MHz max (indicated as 50 MHz max in one place,... 
oppo 105d mod or look for a new cd player ?
In addition to the post cited by Tubegroover, the following one from this thread will also be of interest:12-21-11: Jwt... I think the 95 modded by EVS for about the same money right now is a unbelievable. no comparison to a modded 93 but at the s... 
Transport signal thru mult cables simultaneously?
KN -- My statement about not having an opinion pertained to digital cables specifically. With respect to cables in general, I believe that breakin effects can be and in many cases are significant. However I also suspect that there are a lot of cas... 
Looking for really fine cables at really low price
Hi Bill,In the analog domain 52 ohms vs. 75 ohms is, as you appear to be saying, an insignificant difference. However when it comes to digital signals, the effects which come into play at the very high frequencies which are present to a significan... 
Looking for really fine cables at really low price
Regarding use of the Belden 8402 as a digital cable, keep in mind that its "characteristic impedance" is specified as 52 ohms, which will result in a considerable mismatch to the impedances of the digital components it would be used with. I would ... 
I'm looking for good analog interconnects
Pete, I found specs in several places indicating that the recommended load capacitance for your cartridge, which is a moving magnet type and is therefore considerably more sensitive to load capacitance than other types, is 150 to 200 pf. I also fo... 
Metrum Pavane NOS DAC
Hi George,Yes, per the description I referred to in the datasheet, it is what is referred to as a hybrid D/A converter. But without any part of it being delta sigma, however. As defined in this Wikipedia writeup, it uses a segmented architecture, ... 
Is DEQX a game changer?
Thanks, Andrew (Drewan), for your always valuable inputs.For the time being, at least, I’ve completed my assessment of the two correction filters I described in my previous post. The clear winner was filter 2 (the one that was created from measure... 
Metrum Pavane NOS DAC
Yes, that appears to be the case as far as I can tell from the datasheet, George. With the slight qualification that while the D/A conversion is accomplished by a resistor ladder, strictly speaking it's not an R2R ladder (see page 19, pdf page 20,...
