Hi,
Yesterday I received a big box from China.
A few months back when Kingwa and Audio-gd announced about the ”hobby-project”, the optimized TDA1541AS2 dac, I couldn't hold myself back. I have a weakness for the 1541-sound. From memory I found the sound soft and easy flowing... Maybe too soft.. Also the regenerated powersupply in the TDA-dac attracted me. Link: http://www.audio-gd.com/TDA1541S2/TDA1541EN.htm
When Kingwa explained that the only choice for a matching circuit design was his Diamond Differential and that the capacitors had to be the RIFA PHE426 or the PHE450's, I believe him 100%. The TDA1541A can absolutely sing beautifully if they are implemented right and with Kingwa's ”body of knowledge”, I am confident that it will be at its best. Kingwa is actually living audio designs and has gathered a massive stock of this knowledge through the years. Still doing it.
In my case, I have an old Quad 66 CD-player with a reading problem that hold a TDA1541AS1 Single Crown chip. So I only need to get another one.... I let Kingwa know about my plans.. I read up on this subject with the selections criterias of the TDA15141A. I bought a cheap and ugly Rotel CD-player that hold a TDA1541A, unsoldered the chip and then I had two chips... This to start with in my continous hunt for another Quad 66 CD player to get a perfect match (S1 Single Crown)..
During my readings on the internet I found an old DIY-thread that ”died” 2007. The thread had a few members that had bought the most desired version, the TDA1541AS2 Double Crown.
I sent a PM to a member in the thread and ”Bingo!”. He answered: -Yes, I still have them.
I bought the pair, of course. The Quad 66 CD-search was called off. Kingwa got my definitive order of the DIY TDA-dac.
The Big Box came yesterday, as said and I put in the S1/A chips for a few weeks burn in and initial testing before the S2's goes in.
This HUGE dac really sings beautifully already. The ”missmatch” of the present chips inside is impossible to spot. The plain A-chip is a good pair to the S1. I think I was lucky to find the ugly Rotel player. The specific serie of the A-chip also has selected (S1 single crowns and S1 Double Crowns).
This dac is a ”Statement, a tribute to the TDA1541A. One of the best dac-chips of the 90's” The dac is HUGE, also the sound is. The sound is rich and embracing.
My new experience with this regenerated power inside the TDA-dac is definately a success. If You have the funds, go for the regenerated power supply. It brings authority, space, clarity, lush, black background...to another level.
To just give an idea of its size.... Here placed over the Master 3 and the left side, the pile of Master 1 (preamp) , NFB27.77 and the R2R-7. (Headphones are HE500 and HE6)
