Sennheiser HDVD800 Headphone Amplifier - Page 162

post #2416 of 2937

Up and running with the new equipment.

Macbook pro -> toslink -> uber Bifrost -> HDVA600 -> CH800S -> HD800.

Great sound right out of the box.  Very revealing of the instruments.  Soundstage is impressive.  Plenty of bass and the mids are super.

I tested the rig with the LCD-X too and they sound great with the gain on the HDVA600 turned down to the minimum.

 

Thanks, all, for your help -

One of the things that was eye opening when I auditioned the HDVA600 was the bass and authority it had doing so.

It's a last resort for me with SS amps but one I'll be happy with.

I've tested the sound on a variety of music, so far:  old Alabama, Alan Jackson, Carole King, Adele, Albert King & SRV, Allen Toussaint, Jeff Healey, Kansas, Led Zeppelin, Yes, and currently the Flecktones.  Couldn't make "Close to the Edge" work - too much treble.  The rest of the music sounds great with the HDVA600's gain in position #2.  I am surprised (a bit) at how good the bass and mids sound, especially the lower mids.  IMO, the lower mids and transition between the bass/mid is the best I've ever heard.  There is zero mud about these cans.

 

After what I had heard about the HD800, I was expecting a brighter sound.  It seems the HDVA600 is matched well with these cans.  The Flecktones sound awesome...Victor Wooten's bass is amazing.  :beyersmile:

Glad you like it. It is such an understated amp. I have that cost thousands more and not really better. Regarding the so called bright hd800. It's all about detail and synergy. When all is ok it's extroidenary sound.

Just one more comment.  The HDVA600 doesn't get hot at all, unlike my Asgard2 on which I could fry eggs.  :-)

Can somebody explain? The gain switch of hdvd 800 influences somehow on SE inputs?

No, its SE out, that is influenced. I quess some sort of compromize of their design to get the best possible sound out in balanced mode.

Originally the reason i went with this amp. Had the choice between it and the Leben.

The gain influences the RCA input to the amp.  I'm feeding the HDVA600 with RCA interconnects from the Bifrost DAC (that will go away when my Moljnir with balanced outputs arrives next month).  I don't know exactly how the gain works, but it changed the sound of the LCD-X quite a bit.  Maybe it's because the HDVA600 is designed to drive the 300-ohm HD800, not the 40-ohm LCD-X.

Gungnir maybe? (Mjolnir is an amp)...  

with the gain you can control the level you get in the rca input, if your it's too low, you can add some gain, if it's "over modulated" you can decrease it.

the impedance would affect the lcd-x whatever gain you're using, that remains the same.

Yea, that's it.  I keep getting those Norse words confused.

I'm listening now.  What I find is the LCD-X sound better with low gain and more volume.  But, it's subjective and depends on the music.

Still a WIP.  The HD800 sound great with the HDVA600, so anyway that was my main motivation for buying the amp.

Thank you very much. 

The gain switch works only with RCA input? 
I read in the instruction that XLR-4 can be regulated by gain too. If it's right, what position of the gain switch would be optimal for HD800? (Note that I mean HDVD 800 only, without connecting to in any DAC)

The instruction manual says the gain only changes the RCA.  When using balanced mode, the gain is fixed at 16 dB.

Instruction manual is right, tested live on my hdva600 on balanced inputs (using an adapter cable from my rca dac, because i've not a balanced dac), gain only changes the RCA. RCBinTN, compliments for your buying, you'll see it's an incredible setup.

post #2429 of 2937

I can change gain to se outs, while using balanced inputs.

Quote all, very very underestimated amp, incredible match for hd800.
