Default Philips multi-bit DACs -- not R2R?

The following was recently posted on a ComputerAudiophile thread:

No Philips designed DACs are R2R -- that designation refers to a series of resistors controlled by switches. Philips used transistors as current sources though which gets around the glitchiness of the R2R approach. Rather than relying on matching of resistors Philips adopts an active DEM (dynamic element matching) approach, at least for part of the DAC array in the 1541, though not in the 1543 as that's the economy device.

I have used it to replace a TDA1541A S1 in my Revox B226.

I found greater transparency and better bass.

There are also available 8x TDA1387 modules available for not much more money.
I have some but have yet to try them.

Hi Andi,


i make this module

HIFI 8PCS TDA1387 In Parallel Module Replacement Substitution TDA1541 TDA1541A D | eBay


also work in my Marantz CD583 as direct replacement without any modifications.I can conform that the bass is more punchy. So it seems to be a cheap alternative (€6 incl. shipment) for the TDA1541A.

Hi guys, I´m very interested to try one of these modules for my dac.

I have found another version which seems to be an "improved version"

1PC new 4 parallel TDA1387 Module Can replace TDA1541 | eBay

What do you think? it would be better than the 8x paralleled chip instead?
