Hmm, very interesting amp indeed! I do notice the input impedance is quite low at 6.3K (SE); 12.6K (BAL). Did they recommend a preamp for you? That is going to be the key between this being a good or great amp. I believe you'll need an active preamp, not sure a passive can achieve a suitably low impedance.

His is a mini-NSL built in a smaller chassis with dac - and I'd guess the volume control is through internal i/v conversion of the dac - so no need for a preamp.

He said i will have an fully integrated amp version with their special dac included also.specifically tuned for driving hard to drive headphones..a headphone amp he never made before...so no need for a preamp he told me....and the transformer will be outside in a seperated case as there is no space for it in the main enclosure and also to get the lowest possible noise floor he told me!

 

to be honest..i dont know exactly what he is cooking up..i gave him what kind of input,output and what headphone i wanted to connect it to..being a he500 and he6 (that i will buy next year)..for the rest i gave him 'carte blanche' to cook up the best sounding headphone amp he could make for those particular phones...i literely told him: surprise me... as i know he is a magician in making very good sounding and simple classy looking amps...just as i like it!

 

he told me that the outside will be simple (so he can spend the money where it counts he told me)..people wont probably even recognize that its something special from the looks..lolz...

 

.just one red cherry wood knob for volume..and a pair of 3pin XLR for my Toxic Black Widow headphone cable..nothing more..not even a on-off switch..backside only has 1 USB input..and a 4pin XLR connection for the transformer casing...nothing more....every penny i paid him will be to get the best possible reproduction of the music that the source will give it... i even get it delivered without feet!! as i already have some very good ones that i used under my evil 337..i kept those when i sold him... and i tiold him about it...so he decided not to put any under the amp! now thats what i call customer service!! :wink_face:

 

and Khaine..am inpressed that u remember that about my amp...lolz... pls dont say u want same kind of amp also....

Well that does sound quite spartan indeed with only XLR outs and a USB in. Atleast the transformer will be separated, but it would be ideal to get the DAC away from the amp, but he's the expert and that is what you want. Looking forward to your impressions :)

Hifimanrookie, sounds great. But wonde why you are limiting yourself to USB input? Seem like a lot to spend not to give yourself a little more flexibility.

i agree on the dac thingie..and i asked him about it...but he told me (and dont kill me if i dont say it correctly..am not technical) that by building the dac part into the main enclosure (apart for being more compact) he could keep the signal line (only 1 - usb to xlr) as short as possible and everything balanced from input to output....the dac compartment will be isolated..

 

and i quote:

 

Every signal trace on board has been carefully designed and tested. It features a complete DC path to ensure ultra low jitter performance. Another feature that adds to the signal performance is the microprocessor is not used in the control circuit. The less the clock contaminates the signal the better. The unique analog output stage uses a design similar  to those in our best solid-state preamp, the BC109CP2.

 


The digital to analog part of the machine will support anywhere from 16 bits to 24 bits - 30KHz to 216Khz and anything in between,  including 16/44, 16/44.1, 16/48, 24/96, 24/196 and more.

Always a fan of minimalistic design. How many clocks for the different sample rates?

yeah me too..thats why i loved the look of my sold 337 so much...simple and to the point...

 

to be honest..i really dont know..he did tell me i dont need any specific (windows) drivers for the dac component... but as i said..i am no technical person...and he didnt tell me... and i understand he is sort of mysterious about those kind of things..as i read in a review about his bigger brother the NSL that he didnt want to mention the brand of the OPAMPS he uses in that amp...he says its not important to know what brand they are..but how good the amp sounds with them in it... he is a weird dude..lolz..just like me i guess.. :D

I know what u mean..but by introducing more signal lines (like coax or optical) it would only take more space in the case and make it more complicated inside and so possibly conterminating the usb signal line..and i already have a dedicated laptop with ssd with lots of lossless music on it just waiting for my new amp...so I dont need any more inputs... wink.gif

I just have good memory - not really interested in any SS design except the Master 8 or Dynamite. But I do remember remarkable companies and their products =p

He may be different, but his stuff sounds fabulous. Good place to put your trust. I am listening now to he-6 through 4 pieces of blue circle gear and could not be much happier. Good clean sound that is very musical. I would bet that you will be very happy (although I do think it would be good if you could to have inputs for an external source for future upgrade, but maybe that is complicating the design too much).

Thanks for the advice..and i have that covered..end of next year i will be moving to our new home in which i will be having a dedicated hobby room..i will convert it into a listening room... With the right speakers..And u guessed it..at that time i will be contacting gilbert again for a speakeramp system .. biggrin.gif

Wait a second... 4 pieces of bc equipment? Wow..am impressed! Lucky u!! wink.gif
Well..i will also be getting a plc thingie fx2... He told me that would improve the noise floor on the source being the laptop. And i trust him on that..
And another thing..i never thought i would run into a fellow blue circle owner..they are rare here on headfi tongue.gif

His power conditioners are a great value. Works great for the bc gear, although not so much for me on my low watt tube stuff (all filtering conditions have been poor with that stuff).

I like the lighter HE-6 cable as I don't even notice it. The HE-500 are being used balanced right now.
