Anyone know how good MHDT Labs Paradisea DAC is?

Here's some spec on impedance of my gears:
Linn power amp input impedance: 4700 ohms
Rougue preamp output impedance: 350 ohms
Paradisea Ouput: 2.0V, < 800 ohms
NAD C541i output impedance: 300 ohms
Marantz DR700: line output is 2Vrms, but no mention on output impedance

I've found that most NAD CD players have low impedance, e.g., C542 has 150 ohms. I did not care much about all those spec numbers since as long as one sound good it is OK with me.

Does anybody care about those impedance mismatching? If yes, why many vendors don't bother put them on the spec?

The missing spec required to know is the Rogue preamp's input impedance. If
it's lower than 47kOhm, then it could be a problem with the high output
impedance of the MHDT Labs DAC.

This is from Rogue. As you see they do not provide input impedance. Do we need to care for something the maker does not provide? Or, am I missing something?

- frequency response: 1Hz-200KHz ± 1dB
- THD: <0.1%
- gain: line stage: 23dB
- gain - mm phono: 65dB
- gain - mc phono: 75dB
- RIAA accuracy: ± 0.1dB
- rated output: 1.5V
- maximum output: 30V PP
- output impedance: 350 Ohms
- dimensions: 17"W x 5½"H x 14"D
- weight: 27 lbs.
- shipping weight: 32 lbs.
- power requirements: 115/230V - 50/60Hz

Yes, input impedance of the preamp matters as it mates with the output impedance of the source (MHDT Labs DAC).

For more information read the info on the Burson Audio Buffer, which is a device designed to correct impedance mismatch.

Tvad I am not sure at the moment. My preamp is a BAT VK5i. The Paradisea sounded just as you described. I was very sad to be honest because I was really looking forward to enjoying this dac especially with all the buzz about it.

I borrowed a friends Muse Model 9 Signature Gen III while I had the Paradisea and never gave it back to him...lol. He preferred his Muse separate transport and dac over this player so it worked out for both of us :)
