There's no price difference just NDKs hard to get! There are few on the way to me but not sure when I'll have them. I make no promises until I'll have them in my hands... I still have to wait...
Cheers,
L

which speeds did you get? did you get 90.xx/98.xx ? they appear to be one of the few manufacturers that make 'audio grade' low phase noise XOs in appropriately high speeds to allow synchronous OSF mode ON operation with es901x dacs

where did you go ch1pstop?

Default First Impressions Continued = External power

Got a first taste of WaveIO with external power tonight. Again, I'll hold full review until new caps settle in. External power put my system into another league. Relaxed. While listening I realize that before there was slight tension that is now washed away. Extended bass and lower noise floor. Everything very natural and great texture on strings. Less zzz when there should be sss in femal vocals. Every breath sounds natural and human. Great space around instruments and air. Sound stage is balanced and natural. Live performance really is a treat.

WaveIO does like good power. I struggled to get enough juice. My supply ended up a simple CRC with Panasonic caps followed by a BG F. I had to use a 7805 reg as my low noise discrete reg did not have enough power. Room for improvement here. The BG in particular will take time to break in so I'll report back in a week when this all settles in.

But holly smokes, this is good.

I'm searching for those freq. but no success so far! For now, mine are 22.5792 Mhz and 24.576 MHz as requested by this card. Anyway, this series is limited to 60 Mhz... so there's no go with your specs.
Kind regards,

Looks like a great choice. Lots of power and low noise reg. Good price too. Thanks for sharing that. I look forward to your listening impressions.

good stuff the AMB sigma11 and sigma22 with the main drawbacks for me being quite massive physical size, limited Vout and limited dropout voltage before damage. other than that yeah nice, wouldnt say cheap once youve stuffed it with high spec parts though

Default external power supply

The AMB power supplies are good for audio .I have one working with a Velodyne digital crossover and other as balanced line driver for a long run in a bar.Now they probablely have 10 000 hr . 1 A ,it's getting hot.For Lorian's board i've made the heatsinks touch the top aluminium cover of the box +2 screws.Always is a pain to source all the parts and little by little the price goes up .

Default More Impressions

After a week of burn in and listening I am quite impressed. Extremely full sound. Very balanced top to bottom. All the 3d holographic attributes we look for are available in abuncance. The ability to play HD recorded material a nice bonus. I downloaded some sample tracks and converted them to 96k which is all my 20 year old dac chip appears to handle. Very nice although a relatively small improvement over well reproduced red book.

My earlier analogy of a well done output capacitor remains. Its very clear that that USB is no longer the weak link thanks to WaveIO. It likes good power, but again not as dramatic impact as one would think. Lucien has done a good job with on board power handling. One could be comfortable running off USB power. For full potential external is the route. I ended up building simpe linear power supply with parts I had available. A 12v 100va transformer delivers up to 8a and a bridge rectifier produced lots of DC. I made a CRC filter with about 1000u Panasonic / 36r 1/2w R / Black Gate F 100u. A 7805 rectifier gives 5v. I followed this with a small inductor at 1.5ohms and put a 50u Black Gate N right across the WaveIO terminals. The filter after the 7805 was to clean up the noise from the 7805 a bit. Audibly a small improvement. Ultimately I supply all this from an isolation transformer. Another slight improvement, but nothing compared to impact on the DAC.

The real deal in improvements in sound quality is to be found upstream in the transport. I play all WAV material ripped with Exact Audio Copy. Transport is a PC running CMP2, improvements in the software made rather dramatic improvements in the sound which eclipsed any WaveIO power supply tweeks by a wide margin. I basically run XP as an appliance with a 24mb footprint and a registry trimmed to 600k. These slimmings of superfluous software in the source took me from clean but clinical (digtal) sound to natural organic sound that can puts you in the venue with the performer. I think the key is, with WaveIO and async USB, the weak links are now upstream and downstream. Typically BlackGates and Oscons take about 100 hours to fully bloom, so I will no doubt continue to see improvements over the next month.

WaveIO delivers.
