Did i got clear that all new product from Robs designs have been already spoiled? Quartet and Power supply, and ultima dac which is still not clear if 2025 will be release date.? It wasnt the case previously not to leave at least something for a surprise!

Except the real surprises will be what's inside them... well over 5 man years of development (and counting) has gone just into these two new products.

There are also the Suzi pre-amp + amp, in the pipeline, but maybe that is a John Franks amplifier design.

Correct - I have had no involvement in Suzi.

Hopefully that will stop the Tweakos from trying 100 different power supplies, oh, wait, they are still going to do it anyway

The PSUs are my own design, and the most advanced PSUs available with new tech to isolate RF noise in both directions - from the unit to the mains, and mains to the unit. It eliminates RF noise and also eliminates the other bug bear of PSUs (most particularly LPS) of signal modulated mains ripple components (50/60 Hz multiples extending up to high frequencies).

But yes no doubt people will seriously degrade the performance by adding other PSUs.

What do you expect from tweakers when they found out the power supply of DAVE is $10 off the shelf item and the power supply of Mscaler is a few $ wall SMPS.

If it meets the engineering requirements set by the designer, then does it matter? You’re not paying these prices for the sum of the components, it’s the years of R&D and expertise that cost a lot of money.

If the PSU cost 2p but did the job specified, I wouldn’t care less.

Is the PSU designed to support more than one external component simultaneously?

e.g. could the PSU support the Quartet Scaler and a DAVE 2?

Maybe „Quartet„ does not stand for 4 million taps or 4 chips, but 4 different solutions in one.
1. Power supply
2. Upscaler
3. CD transport
4. EQ
Just a wild guess. Or it means all three.

According to the latest video of Rob, which now seems to have been deleted by the uploader, Quartet has 5 * FPGA chips and 4M taps.

Is Quartet the same as the new rumored "Dave Scaler" or is that going to be a completely different and more expensive upscaler?

The scaler for the Dave yes.

I think its not a good idea to feed both Dave and Scaler off the same supply as noise gets a short route from scaler to DAC. I rather keep them separated.

The new scaler's PSU solves only one problem.. noise from the Scaler to Dave.. but Dave remains sensitive to other mains RF coming from household electronics and perhaps other HiFi chain components..

So i keep benefitting from my PSU tweaks in Dave.

No - the PSUs need to be independent to prevent RF current flows. The new PSU works by having an extremely high impedance at RF - in particular the 1MHz to 10GHz band. This high impedance means that RF currents can't flow. By combining PSUs together provides a lower impedance path to couple scalers to DACs at RF.

I'm sure the new scaler combined with Mojo2 or Hugo2 operating on batteries with direct connected headphones must be a delightful experience

Im eager to hear that

Same here interesting whether units will be shipped in paralell to the announcement or later the year.

Did you design the new power supply? If not, did Chord design it? Or did you get it from an external supplier? I'd appreciate an answer thanks.

Yea, i'm going to A/B the old M Scaler vs the new one, my dealer is going to have it. I hope I'm impressed, I guess we will see.
