Hi.

I have been experimenting with several input devices for the pcb 1541.

It is indisputable that Iancanada i2stopcmboard is essential. I have tried these three things that work well with i2stopcmboard.

A) Fifo and dualxo from Iancada connected to rapsberry pi by i2s. Without a doubt it is the best option, especially with good cloks and if we use the U.FL.

B) USB AMANERO. The one used in two ways, with Fifo and dualxo of Iancanada in a way that uses the dualxo clocks, or using Amanero's own reclocker. Much better with Ian's pcb, but it's also an expensive solution. Using Amanero alone is very economical, only $ 70. In this case it is highly recommended to use LDO feed for Amanero. Usb is for me the worst communication system with the dac compared to spdif and especially i2s. Anyway with fifo and dualxo of Ian is very good, so it is very possible that a plate with these concepts is a great solution.

C) ALLO KALI. I'm a fan of Allo products, I think there's no better sound for that price, but I have not considered using Allo Kali as a reclocker because I want to use better clocks. I have not used Kali until I have had a problem with Ian's fifo. The result has been surprisingly good, almost as good as Ian's pcb's, but Ian's pcb and good Crystek clocks are $ 300 and Kali are $ 70.

Something very surprising that I have experienced is that there is a critical component in this system, it is easy to think that they can be clocks or low noise feeding, but it has been surprising that only the jitter with Kali has disappeared (at least the one I can perceive ) When I have used U.FL cables, I recommend that you use what you use as a reader connected to i2spcmboard by U.FL.

More and more in love with this great sound. Has anyone else finished your project?

Regards

Default clock options

Jjazz
I can add a couple of thoughts on input options for I2S. For reference, I still use Ryan's V1. Will build out V2 in a future build, but I2S options would apply equally.

I have had great results with following chain. BBB to Acko S03 isolator/reclocker to Ian's I2StoPCM to Ryan's 1541a board. Point being the Acko S03 is an option to substitute for Ian's FIFO rig.

WRT oscillator costs, I currently use NDK NZ2520SD clocks which were available @ DIYINHK for $8.00 usd. They were comparable to the Crystek option but at much lower price. Acko used these on his S03 but could be equally effective on Ian's FIFO.

In the past year NDK upgraded their product to the NDK NZ2520SDA. It has around -12dB lower phase noise. Check out Lucian's group buy thread for user experiences using these new clocks. In these user testimonials they are referring to the impact of upgrading the clock on Lucian's very fine WaveIO. Extreamboky has a really good review. He cites one of those need to re listen to music library moments. Point is the impact should be same or greater using NDK SDA on the S03 or FIFO or Twisted Pair Hermes. I just yesterday received a pair of these new clocks from Lucian and will report in the next few weeks my comparative results. I expect another quantum leap. Most people seem to believe these clocks are superior to the Crystek. If Lucian's GB is closed, it is useful to note these are also available at DIYINHK.
Sorry for long post perhaps off topic to Ryan's GB thread. I am a Ryan fan and always keen to see people like you get the most out of his fine work.
Feel free to PM if you have questions.

Hi Walter and Jorge,

Looks like you two are of the very few who have reported using my PCBs, im sure there must be more out there with around 200 pcbs scattered around the world.

Yeah Ians I2S to PCM pcb gives great results, a total game changer.

Let me know how you go with those new NDK clocks Walter, i've been having a play around with some of Andreas clock boards lately.

I'm not sure this is the best place for a discussion as it was only intended a list thread, not that im bothered by it, just not many people viewing I think. Jorge, It might be best if you ask your questions and enquieries over here.

Ryan

Recently got Trafo and BOM for Psu so stay tuned (just got to make time/priority)

For me output will be either DC1 or Sen but getting my head around CCS at the moment (but may just use Lampizator that is in my current DAC for the meantime so as just to get started)

Input will be basic - spdif using CS8412 etc. Until I can get my head around IanCanada I2S etc. And the buy it.

Hello all,
just to report that Iancanada i2stopcmboard works also with hifiberry digi + pro i2s out.
i tested on a pcm1702 da and it works.
When when i have all power supplies i will connect to 1541 distinction v2.

hifiberry digi + pro i2s out + Iancanada i2stopcmboard is also a cheap solution...

I'm using hifiberry digi + pro i2s as my transport for the soekris dac. This is great info for my future project with the 1541.

Sorry M3744. I have no experience with the Pi. I went with BeagleBone.

Sure, happy to...
BTW, there is a build log going into some detail at my blog.. diyAudio - wlowes

While it evolved over time, I use Linux processor (BBB) running distribution by Meirio producing I2S. I use an Acko supplied cape on the BBB to Acko S03 isolation / reclocker to IanCanada I2StoPCM board to Ryan's Distinction V1 board. This feeds a Lampizator buffer running 6n2p tubes. The blog outlines various approaches and tweaks that resulted IMHO a top notch result. In general it came down to extreme attention to power supply at every turn, good clocking, and isolation from vibration and noise. The music is stored on a NAS and the whole thing is controlled from my Android phone.

The signal coming from the front end is preserved in the rest of the audio chain. Volume control is a fine autoformer by Dave Slaggle. The amps are 110w OTL tube amps using 6c33c tubes. All of this lets Ryan's Distinction board shine. Lot's of micro detail. Kind of natural in the room experience.

I think the biggest challenge in these BBB or RPi processors is learning enough Linux to load the software, configure it and make the network connections. This part is not for the faint of heart. The result is very good sound at relatively low cost, but it can be daunting.
