Transports / Re: Raspberry PI transport with I2S output into TDA1541A

This pic shows the main reason, why I use Roon.

Multiple end points.

There are other reasons, why Roon is nice.

As you can see, the Raspberry Pi, is just one end point in my home.

If you look closely, the different end points can and do play different tracks from the library, or from my integrated Tidal streaming service, or any Internet radio station.  All easily accessible through my Roon client.

Hey Mr Oz,

Just interested in what media player you are using with your Raspberry Pi and what system are you loading on to it?
:D Cheers :D

I use Roon in the back end,,, it doesn't reside in my audio system.   I have a headless Rock server, that holds the database indexes to my music files stored on NAS.

Roon client on my phone and/or tablet, talks to the Rock server to queue music, and tells it to stream to my desired endpoint.   

It is a different architecture, and it means, I do not need a PC in my audio system to enjoy music. I just need a convenient smart device with the roon client.    The rock server sits in my computer room.

Here is some more info....

Agreed, Steve, I lost it at one point chasing ultimate detail and only focusing on that, only to loose the body...or meat on the bones, lesson learnt there :)

Have some AB's to replace the drain/balancing resistors on the Mundorf HV main filter caps, not sure how much difference they might make with a change but as I find components in the PS do show their sound signature often, and especially in a valve amp I'll change them and see.

It is a richer sound over all, more natural.

Thanks to Steve and the KD forums again  8)
Richer and natural, That is what i find is most important and why Allen Bradleys can be great, unfortunately most people lose sight of its importance

I'm glad I take heed to what is done here, the AB's where a tad over rated values but close enough and the sound is better layered, instead of a tambourine being more of a single sound you hear all the little clangers that make the sound of it, brushes and strings, maracas ect' all sound better layered. It is a richer sound over all, more natrual.

Replacing dropping resistors in the feed to the pre amp valves with these, the current ones are kiwame resistors. Maybe some to replace the balancing/drain resistors that are across the Mundorf main filter caps also.

Trying to upgrade from those Kiwami's that are still in the amp, I replaced some Kiwami's with Shinkoh's last episode :)

Great resistors, but new they can sound a bit dark for a few days, but clean out nicely, i use them in tuning,  in only the right positions till the balance is right. Let us know what you think of them, but only after run in.

Waiting on some AB resistors for some positions in my amp, I haven't used them before but from what I read here and others experiences I'm chomping at the bit to install them once they arrive  :)

I have been doing some serious listening to Danny's Computer transport and its incredibly clean and clear, You can certainly hear a lack of mechanical noise, and a certain smoothness results. But after listening to the Wadia transport with the vintage chips, the same chips as the marantz 94s ect. These early chips are made like the TDA1541 and it shows. These are bigger than the TDA and have the same kind of lower midrange weight and gut gravel in the voice. They are coarser and a little ruff but so real with real flesh and bone, real body, and most impressive...... Dynamics. Its a shame we can not have the best of both worlds. Pictures of Danny working on the computer transport.
I moved from a PC and DAC to vinyl, and now to a CD player, I'm not in a hurry to move back to PC as a source for similar reasons.

When I used a PC I had what I perceived as a quieter background but I lost something else.
