I am a tube lover, and run an all Audio Note DAC-Pre-Power system, but also use SR-007 MK2 and a Stax SR-717 amp.
I have owned quite a few DACs over the years from Naim, Meridian and Musical Fidelity. 7 years ago I came across the None Oversampling DACs and fell in love with the organic and smooth sound. I would characterise the sound of the Meridian and Naim DACs as good but 'HiFi'. I liked them on demo in the shop, but sold them inside 3 months of owning them. They just didn't do it for me. I was picking my favourite CDs on SQ replay, and avoiding those that sounded harsh or brittle.
Don't believe the rumours, None Oversampling DACs can sound VERY detailed and yet have the smoothest treble possible in digital replay. I have learnt to re-love my RedBook collection as it is now so close to a good vinyl rig. I listen all day with no problems. Ok tubes need replacing every 2 years, and it needs to warm up for 1/2 hour, but it glows in the dark and the sound is just so right!
I am using a Mac Mini and Pure Music into M2Tech EVO full stack including regulated power supply into my new Audio Note DAC 3.1 SE kit. The kit costs 2,250 US and you get (once assembled) a truly high end DAC with great quality parts, solid design and fantastic sound quality. I would say it will compete with DACs 3 times it's prices, especially OS units.
The kit took me 10 hours to build over 4 nights, and was a truly fun experience. The thing is, after you have built the kit, you understand the layouts, and can appreciate the way it works. It is very easy to bolt in upgraded components later should you want to as the case is big and there is space left.
BTW if you think 2k sounds a lot for a kit, this is no ordinary kit. Check out the parts quality. And the Lampizator is more money and look in the Lampizator box, looks cheap to me. I haven't head that DAC, but have heard the MHDT Havanna and though nice, the Audio Note is much better in every respect.
My 3.1 DAC has:
1. No Oversampling
2. No Brick Wall Filter (makes a big sonic improvement)
3. Tubed rectified Power board
4. Separate power supply board for the Digital PCB
5. Quality Digital PCB with toroidal transformer
6. Custom Audio Note I/V transformers to transfer the signal between the digital and Analogue boards
7. Output transformers for maximum dynamics and energy (plus 8 ohm low impedance) output to your pre-amp
Also I have the ability to choose my favourite tubes, in this case a Bendix 6x5 for the Power supply board,
and 2 x Tungsol 5687s for the Analogue Board.
