Hi tagheuer, I experienced something similar passing from Teralink X2 (based on Tenor) to Lucian's WaveIO. My difference was not so huge (I used X2 -> I2S -> TP Opus) but clearly noticeable, particularly in the treble area and microdetails.
I'd like to suggest you another cheap improvement I experienced very recently.
Some month ago I purchased a usb isolator board based on ADuM4160 but it didn't work with WaveIO (as expected) and it has been on a shelf from then.
Some days ago I inserted the board on the usb connection between the
external HD when my library is located and the notebook, just for a test
before listing it on eBay. The external HD has always been powered by the stock
switching power supply.
The improvement in sound quality was immediately clear especially in
the treble that are less harsh than before.

Default Great product!

Hi Lorien


The WaveIO arrived late yesterday (Friday) thanks but I did not have time until this morning to set it up - which took under an hour including adding an RCA socket & downloading/installing drivers for Win7. I am using its isolated S/PDIF output until DEQX sort out the firmware for I2S input - and your daughter board arrives! I am also using an AQVOX power supply which I bought some time ago for my Hiface that cuts the normal USB PS & inserts its own regulated analog +5V.

It sounds excellent - very natural & unforced but very dynamic on my DEQX-active Tikandi loudspeakers - and significantly better than anything else I have tried: Hiface, Halide, Audiophillio etc. Even listened to Handel's Messiah while watching the Aussie Rules Grand Final. So many thanks for a great product!


Cheers
Rod

Hi Lorien,

does/will the WaveIO support native DSD64/128 files?

Hi,
Question from a real beginner:
On j10 spdif, hot point is on the square pin, but to use the galvanic j11, do i need to put the hot point (center of my coax cable) into the one called spdif, a rounded hole and leave isol called square one for outside of the cable ?

Thanks for your help

Hi,
I read you used isolated spdif and i would ned a small support on it.
Can you just clarify for me the isolated connexion on j11: inside ( hot) on the square, called isol or rounded hoe ( called spdif) as lorian gave me direction for j10 and same time recommended not to use it

Thanks for your possible help

Francois

I'd like to connect a WaveIo board to the I2S input of a TDA1541A. Some posts in this thread were not so clear to me.

regal, I'm afraid I've not perfectly understood the issue with the LSB being mangled. Could you please elaborate a little?

It is lower than optimal but light years ahead of the stock 470pF cap done spec'd by Phillips. I am going to play around with using the clock feeds from Lucien's board (88.2) to double the speed of the DEM signal without messing with more components. But that is in the future, as I am pretty happy with this initial setup.
wlowes, how can you obtain 88.2 KHz from Lucian's board?

Thanks a lot.

Paul

Hi Massimo,

Thanks for the info on USB isolator. Currently I'm using a CAPS 2.0 music server and use SOtM tX-USB Audiophile PCI to USB Audio Card for output. The internal solid state HD is filtered by SOtM In-Line SATA Power Noise Filter. The difference is quite noticeable as compare to direct USB port from the motherboard.

I suspect maybe the spdif converter at the USB-TE7022 card is not good. So the next thing I want to do is to bypass spdif conversion on both USB-TE7022 and DAC-AK4396 and use I2S signals to connect both cards.
But may I'll give a try on the ADuM4160 some day. Just to satisfy my own curiosity since you recommend it.

Cheers all...

Hi Paul,
See post #1084. I use L5 pin as a source of 176.4Khz for DEM. I generally listen to 44.1 material although quite nice at 88.2 as well.

DEM reclocking provides nice SQ pop. This 176.4 clock source just makes it more liquid and removes any hint of harsh edge to the upper registers. FYI my 1541 has fully tweaked power and tube output. I2S from J2-5. Transport is MPDPUP on Alix. All together this pairing is WaveIO is pure magic IMHO.

Paul, if you are asking how to play at 88.2, just hook up the non isolated I2S output from WaveIO using the connectors described. I solder direct to the pins of the 1541 and it works fine. Don't forget gnd. Some people claim signal needs attenuation. I just use it direct from WaveIO. 1541 will play whatever source you feed it up to 96.
