OK.  Fair enough.  We may be comparing apples to oranges here.  My Havana is balanced, so again, the circuitry is doubled, due to the balanced setup.  They (the Havana DACs) sound quite a bit different when using the balanced output.  This can be verified by comparing the two, along with looking up reviews of the balanced version.
 
I also changed out the two 5670 to Raytheon JRP with windmill getters, which are as good sounding as the 396A tubes.

Actually, you positive comments mirror the pro reviews of the Lampi Dac generation 3 and earlier, all of which used a DS dads. Also, not all DS oversample! The DS Lampi had UPsampling built in, but there was NO oversampling in the chip or the circuit as far as I understand and I asked  for clarification several times.

Having said that, I agreed that R2R type Ladder DACS do have the natural advantages you describe and you do have to work harder with DS Dacs to approach those desirable features. However, some DS Dacs can handle pure DSD and from what I hear, that is something else! No ladder Nos Dac can do dsd from what I understand. By next year, I expect DSD capability to be in vogue and ubiquitous among DS DACs in 2014.

Moving beyond archaic spdif... it is time! That being said I currently only have vinyl  :lol: . I actually got tired of cheap transports going to poop on me. Also wanted to commit myself to music and being picky with albums I really want. My rejection of digital had 0% anything to do with sound quality. I don't even have the words for the level of quality digital can do with clear power other than you won't assign a notable advantage to vinyl in anyway; at that point it is just different.

Good points.

Vinyl and tube amps are high maintenance! LoL

Actually I use a 3875 amplifier. I'm going to switch to an F1J in the future most likely, but then again even though I got the PCB's, I just don't lack much to need the switch.

You seem to have a nice setup there. Tell me more about the amp...it looks interesting.

One comment though, not sure about teh granite. i hear it is the worst thing to use as it amplifies and conducts vibrations. I heard it better to use felt maps and they are way cheaper too!

I use a NAD c375BEE integrated (Modified by a Swiss company to has a small negative output impedance). Among other things, the mod makes the amp stable down to 1 ohm loads and maybe a bit less.

Sources are a modded Denon Universal DVD player, where the SPDIF signal is stolen form the chip leg and run direct to a new coax output, bypassing the sound killing long PCB taxes. I also have an Onkyo SACD player which uses a discrete output stage. I do have a slightly modded SqBox Duet receiver (caps upgrade) and fed by a purpose built power supply in the Lampizator Dac. Finally I have a McBook pro using an Empirical Audio Offramp 4 spdif converter...all feeding the Lampi Dac. I also have a DSPeaker room corrector/DAC/Preamp, but I have not put that in the chain yet.

Finally, I have a pair of Heil AMT Syrinx speakers and an 8 inch Energy stereo sub (single). I also have the baby Heil speakers (the Aulos) and Intend to run that series-parallel with the Syrinx on special occasion, using my vintage (US power) McIntosh 2125 power amp (120WPC into 8ohms)....I have a 600W rated transformer and the Mac will draw a maximum of 432W at peak.

I just updated my system. There are some improvements, but I miss stereo subwoofers. I mix the big sound experience sometimes with the and the Hawthorns.

That photo isn't mine, I don't know why but it gives you a random one if you don't have one.
