A friend came over the other weekend as he had got hold of a DECO Audio DAC. Deco Audio is a UK HiFi company who have put together a valve DAC based around the 1543 chip, for the princely sum of £540. We did a compare and contrast against a few DACs I have here: Weiss DAC204; Synthesis Roma; and, the Chord Qutest.
The front end was my dCS Network Bridge into the Chord M-Scaler powered by the Ferrum Hypsos set to 14v.
I was using the Cardas Reference into my Icon 4 and then into the Naim 300DR and SBLs.
The Cardas are worth noting, and I will mention them again a bit further on.
I won’t go into the minutia, the overall most enjoyable sound on the day was the Synthesis Roma. The most detailed was the Weiss DAC204, also have more dynamic clout. But, what of the DECO?
The DECO is a stone bonker bargain. Very good with voices and acoustic instruments. The sound staging was excellent in this system. Removing the M-Scaler from the equation caused the aural picture to collapse into the centre, but it showed it WILL respond to upgrades at the front.
The weakest DAC on the day was the Qutest. It didn’t sparkle or shine. This led me to consider the Cardas Reference. When powering the M-Scaler with the supplied SMPS I found that the Chord had a slight degree of glassiness in the top end, I therefore swapped the SMPS out for a Krisdonia battery, which I ran at 12V, as done by Rob Watts. This improved matters, but also reduced the dynamism by a tad.
When listening to the Ferrum Wandla I slotted in the Ferrum Hypsos. Damned good DAC. Ferrum describe the Hypsos as a Hybrid PSU, I have spoken to detractors who describe it as a ‘glorified SMPS’. My experiences with the Hypsos have been entirely positive. I LOVE the fact that it does everything the better LPSUs I have do, and that it is adjustable in 0.1V increments between 5V and 30V. Over and above that it supplies a healthy current, unlike the 19V SBooster that I have.
The adjustability of the Hypsos gives you an additional way to tune your system. I have played with it using the M-Scaler, the Sonore ultraRendu and the Weiss DAC204.
With the Chord M-Scaler the Hypsos removed the top end glassiness, as per the battery, AND gave me all the balls of the Chord SMPS.
Having considered the rather over-relaxed performance of the Qutest, and the reduced performance of the Weiss DAC204, I swapped out the Cardas cables and returned my usual Nimek silver ribbon cables. The performance of the Weiss regained its bass differentiation. I confess I have been enjoying this so much I haven’t yet retried the Qutest.
If you fancy a taste of what valves can do in a DAC then I would heartily recommend the DECO.
