This sort of brings up a question for me.  Here are 2 scenarios to compare :

 

1.  Use line out from E9K to Emo and only control volume on the Emo.  This ends up at 9 o'clock or so most of the time on the Emo.

2.  Use pre out from the E9K to Emo and control volume using both the E9K and Emo.  Maybe, put Emo at 12 o'clock and dial in on the E9K to comfortable volume.

 

Will #2 push the Emo harder than #1? If yes, will this connection loop have any negative effect on SQ?

Check it out!

 

I will, indeed!  Again, I'm really happy to hear you're impressions, having actually tried the PM8004 speaker terminals with your ortho!

 

Thanks for your advice, above.

 

More later,

 

Mike

I plan to use the speaker amp to drive HD-800/LCD2.2

 

If I were you I would get the following:

 

1. Headphone connectors to 4XLR.
2. 4XLR to TRS jack for headphone amps.

3. 4XLR to 4 banana plugs for speaker amps.

This would be more future proof as you won't have to care about the ground being shared or not.

I love the way you guys are thinking!

 

On reading this, I just now inserted my Decware ZSTAGE (single-tube triode gain stage, essentially a pre-amp with only one set of RCA inputs) between my DACmini CX (DAC line out) and the Mini-X, turning down the gain on the ZSTAGE to nearly zero, while turning up the volume on the Mini-X to maintain the usual SPL I prefer at the ear pads.  This took me from 9 o'clock to about 1:30 on the Mini-X volume control.

 

 

 

 

I've only listened for a few minutes, but I can't really say it's more transparent - probably because the ZSTAGE itself, running an NOS 1956 Radiotechnique 12AU7 is less than than perfectly transparent, of course, but surprisingly the dynamics are still excellent.  I had expected the dynamics to suffer with a decrease of input voltage to the Mini-X.  I'm enjoying the tube buffer action, though - the tube adds some warmth and this tube is known for its fantastic bass. 

 

The LCD-2 rev.1 is directly connected to the speaker terminals, having cut off the TRS plug of the stock Audeze cable.

 

The RCA interconnects are Emotiva's - still on sale at the moment - an incredible deal at $12.74 each.

 

 

 

I've also replaced the Mini-X 18AWG unshielded power cord with Emotiva's 2-meter 12AWG shielded power cord (also on sale at the moment), connecting it to the Mini-X by using a Pangea C14 to C7 adapter.

Wonder if a resistor box solution would make the sound more transparenttongue_smile.gif

The question begs to be asked, for $189 the emotive seems to be a great value.  A quick ebay search and one can find dozens of vintage marantz for sale for the same price.  Many are 10, 20 and up to 50 watt variants.  Would one be better served going that route versus the emotive?  Looking at getting the HE-500 or HE-6 in the next month or two, trying to plan ahead as far as amping goes.

 

Thanks guys

My answer would be :

 

1.  personal preference!  brand new product with warranty delivered to your door vs. a used/vintage marantz without warranty.

2.  From what I've gathered, Marantz does have a little upper hand in SQ.  Without owning both at the same time, can you, will you know/tell the difference even?

3.. Are you willing to take the risks associated with vintage Marantz for the pros they offer? or would you rather play it safe with a brand new product like the Emotiva with a solid perfomance/price ratio?

 

Good luck!

Thanks for your insight.  The ones on ebay I am looking at have warranty, have been cleaned and gone through etc.  Given the price of the headphones, SQ will be my deciding factor.  Thought I would ask here before I made a decision.  Had a chance to demo some emotive mono blocks when I was building out my home theater.  Was impressed with what I heard, and the prices were fair.

Remember....  you can always return the a-100 if you don't like it.  

post #1527 of 3639

If you live in the US. Technically you can outside the US, but after all the taxes and handling and shipping, it's already a loss.

He's located in LAbiggrin.gif  I think anyway..

do tell about the ebay vendors.  Now you got me interested too.  I still have space... at work tongue.gif but the Emo is not going anywhere either.  My friend is putting a hole in the front panel for me once I decide on what jack to use.  The panel is thick but not too bad.

I'll be bringing one to the LA meet on the 20th of this month. Less than two weeks away. You can test it out and see if it's your cup of tea. Not sure when the sale ends, but we could setup a time to meet somewhere like Fullerton maybe so you could try it out. I live in south orange county, so that might be a little far for you.
