PC -> Grace Design m903 -> Van Den Hul "The Name" RCA Interconnect -> Stratus -> HD800 (DHC Molecule)

 

I'm surprised how loud the Stratus can go at, with the volume knob at 0, it gets pretty loud even at 1

Been trying this setup the last couple of days, Sophia 274B + 2A3 and cyroset 6N1P. The results have been good as the setup seems to portray warm and lush sounding on the HD800 though it seems to lack the bass punch.

 

Not sure if it is me but the NOS RCA 5U4G with Sophia 2A3 does not sound so good as it sounded a little too lush to my ears.

I am using the stock 6N1P tube.  Can someone offer a recommendation for an upgrade.  I looked on ebay for a cyroset 6N1P without much luck and I am not sure how to purchase this tube or if it is different from the stock tube.

Thanks for your help!

Try this link for the cryo 6N1P. They are noticeable smoother and fuller sounding than the stock tube that comes with the Stratus.

Without any direct experience I would guess this tube would be complimentary to HD800 or T1 headphones. I found it to be almost too smooth with my LCD3s and switched back to the stock tube.

The EML mesh 5U4G is a punchy rectifier but I can't say how it sounds compared to Sophia 274B. I can tell you that the older Brimar/Marconi/Crosser U52s make a noticeable difference in the Stratus and, imo, would sound very nice with the HD800.

The EML mesh plate rectifier is a good choice for more bass punch. The U52 will offer more treble refinement over the Sophia 274b but with similar low end performance. Personally I like the Philips 5r4gys for bass punch, though it adds sizzle.

If that doesn't work, change the 2A3. It has a greater effect on bass more than the rectifier anyway. The two 2A3's that seem to get mentioned in regards to bass performance are the EML solids and JJ's. Unfortunately I haven't the pleasure of listening to either. frown.gif

too bad the gz37 wont work well, the fat bottle version is like the 5r4gys but even more bassy, but no sizzle or syrup biggrin.gif
