Yeah, I was in a little bit of a rush getting the parts and paid that hastiness in needless shipping costs to revise orders and such. So what I would do is gather all you can from DiyAudio, Mouser, and Digi-Key. Then submit your parts list to the guys on the forum for review and ask about what you'll also need that isnt listed, like wire, terminal blocks, standoffs, tools, etc. Take a week going over it, then make your purchase.

..so, just how impressed am I with the Millenia?  I was up until 4am listening with the it last night/this morning.  What I've noticed since I took it, ootb.. the sound has noticeably smoothed out.  It was on the bright, slightly lean side of neutral.. now, it's smoother, more full, and weighty... though it retains the airy, openness I've come to love about it.

 

I'm kind of befuddled in trying to explain it's sound signature.  I totally understand how many SET owners have found the Millenia to be one of the first solid state amps to satisfy them.  The sound possesses a uniquely elegant warmth & extremely refined liquidity.. while simultaneously sounding unbelievably clean, speedy, clear, detailed, and boasting excellent bandwidth.  I (personally) haven't heard anything quite like it, actually.. it's, quite simply, mesmerizing.  How it manages to sound so accurate and transparent through all this.. I have no idea.

 

It's accurate.. but not remotely fatiguing, clinical, or harsh.  The background is remarkably silent.  I've never heard dynamic swings come across so smooth, well controlled, and effortless.  The tonal purity is hypnotizing.  I simply love linear, wonderfully extended, tight, punchy, fast bass & crisp, airy, open (and again, linear) treble.. but the Millenia's midrange, is nothing short of sublime.

 

This is, without a doubt, one of the finest amps I've heard the HD800 with.

Awesome FlySweep! Looking forward to the schematic of the impedance box when you get a chance, I'm curious how he managed :)

"....one of the finest amps I've heard the HD800 with."

 

Wow, that's pretty cool. I've never heard the HD800, but I was somewhat concerned about whether it's sonic signature would make a good match with the Millenia. Now I'm curious to hear it myself someday. Sounds like it was all worth the wait. Keeping you up all night to listen to your music collection....that's pretty high praise  right there!

Certainly.. I'll holler at Jan about it.

My Paradox will be back next week, Stew.. since that's a common point of reference for us both, I'll provide comparisons on how it stacks up to the HD800.. when both are run off the Millenia.  It's been a while since I've heard the Paradox (nearly ten months, actually.. cause it's been on tour).. but if it sounds like I remember it, I can envision why you like it so much when it's driven by the Millenia.  The HD800 will almost certainly sound brighter.. but that's a consequence of the HD800's tuning, not necessarily the Millenia... whos' (transparent) nature isn't goosing up whatever's getting delivered to the HD800.

 

I'm enthralled with the bass and treble performance of the Millenia.  I'm surprised all over again by just how deep the HD800's bass goes.. and how tight and impactful it can be.  The treble is so silky and clear.. and the midrange is, simply, breathtaking.  The mids possess an intricate liquidity, delicate warmth, and effortless clarity that's very reminiscent of what I've heard from some fine e-stat rigs.

 

If it isn't apparent, already.. I've found, what I deem to be at this point, my favorite amp with the HD800.  My souped up BH Crack is pure joy to use with the HD800.. but the Millenia offers a step up in refinement and seems to deliver more of what the HD800 is capable of.. while maintaining the "inviting" feel that many love about tube gear.

 

I'll surely be toting this along to the next (Seattle) meet I'm able to attend as I'm just as curious to hear how others find the performance.  Never did I imagine that $600 could net this kind of sound from the HD800.

I'm confused by all this resistor box praise talk. Shouldn't that be killing the dynamics in your music? Doesn't make sense to me.

I don't know the technicalities.. but I know my ears.. and my gear.. the LAST thing this rig lacks is dynamics.  It's simply terrific, in this regard, actually.

I so wish I could express what I hear as well as you! But I can certainly agree with you in my own experience with the MG3.

I have to say, as much as I love the Paradox with the Millenia, the LCD2s I demoed a few weeks ago were enthralling. Still on my list of possible purchases.

I had similar misgivings until Jan Plummer explained that with 32W into 8-Ohms speaker amp, there's plenty of power left over after adding resistors to tame the hiss heard without resistors.

 

Consider this: With the resistor box in place, my 50-Ohm LCD-2, which can handle 13Wpc (per Audeze specs), is not only plenty loud with the volume control at 9 o'clock at 8 o'clock, there's no lack of headroom for the most dynamic recordings. Similarly, FlySweep is operating his MG3 > HD800 at 12 o'clock - plenty of power to spare - with no hiss from excessive gain.

The secret lies in the resistor configuration Jan uses.  Since he has published the layout for his arrangement, I don't think I'd be speaking out of turn touching on how it operates.  With dynamic headphones, especially, you want to keep the impedance seen by the headphone low.  In this way the damping factor is kept high and it minimizes the frequency response variation induced by increasing the effective output impedance of the amplifier.

Did he publish the layout for HD-800 somewhere?

I haven't seen the specifics for the HD-800.  He has a "guiding philosophy" if you will for how a resistor divider aught to work, and every layout I've seen reflects that theme.  

 

You (or someone) will have to get the info out of Jan for specifics.

Hi guys hoping for a little advice on using a valve speaker amp for powering my HD650's and Beyer T1's  specifically the minimax amp below.

 

Eastern Electric MiniMax Integrated Amplifier 8W http://eeaudio.com/eeaudio_008c.htm

 

Has this idea any merit and if so which would be the best way to connect the headphones direct to speaker outs via rca y splitter to headout or via something like this dummy load box I have seen being sold on ebay?

 

http://www.ebay.co.uk/itm/RAT-HOTROD-VALVE-AMP-SPEAKER-DUMMY-LOAD-HEADPHONE-AMPLIFIER-LINE-OUT-BOX-16-OHMS-/130978100167?pt=UK_MusicalInstr_Amplifiers_RL&hash=item1e7ee733c7

 

I have never used tube amplification before and its become an itch that just needs needs to be scratched and would like to try both in main hifi system and with headphones the minimax turns up quiet regularly on the second hand market and has had some good reviews. Might going down this route give results on par with a dedicated tube head amp.

 

TIA

I suppose we're all stumped, TIA.  I'm not able to help you, with this, as I know next to nothing about tube amp, or the device for which you provided a link.  Let us know where you end up with this, though!

 

Thanks, 

 

Mike
