Howdy Everyone, Looks like I get to join the snap crackle pop and blow into the mic sound club. This really sucks. My previous monitors lasted over 10 years and these were only used a few times a week for less than 5 years and now they are toast. I've got a 20+ year old Adcom amp sitting here...

Has anyone tried the "I" version of the cans? I wondered how the mic sounded to those that were listening to a user of the phones.   http://www.amazon.com/gp/product/B003WV7890/ref=ord_cart_shr?ie=UTF8&m=ATVPDKIKX0DER

If you are talking about the DIP socket that holds the opamp used in the dac output section, those 561j labeled components would be caps. I have included a pic that I cribbed from another forum that shows the older version of the DAC. In this picture those parts are the more traditional...

I wonder why they did that? It drives me nuts. :-(

Does anyone else hear distortion on Johnny Cash's cover of Hurt at around the 3 minute mark? I am listening to the CD and this is the only CD of the "American" recordings where I hear distortion on any of the tracks.

Perhaps a packet capture could be used to figure this out.

Can you bypass the internal filter and just use the I/V? I am just curious. Also, does anyone have a collection of I/V designs or a link to a web page that describes the various ins and outs, op amp vs discrete, etc?

My ultimate goal is either to do one of the two output sections on that site. :-) I am glad you like it. Post some pics! Quote: Originally Posted by green0153 I could contribute to this thread telling that i have done the Lampizator mod and the difference is huge. I have used a...

I have installed the Neutrik BNC in place of the factory supplied RCA plug. I am using a Blue Jeans cable to connect this to a HagUSB and it sounds wonderful! I will be installing my own version of the FrankenMod soon! I will be sure to post plenty of pics as well. Thanks for everyone's help!

NICE! I have been wanting to roll one of these so I can try an amp with no global feedback. Is there anyone that makes some small wooden chassis like pictured above?

Yea I am wondering if I should even tinker with this thing. I reckon I'll swap out the caps, install some wima bypasses, and swap out the opamp on the DAC board with a HDAM. When is the compass coming out?

Thanks for the heads up Coreyk78!

What about those 8audio boards on ebay? 6DJ8 Single End Tube Head Phone Amp Bare PCB for DIY - eBay (item 300280852169 end time Dec-21-08 07:18:24 PST)

Thanks but I already have an order that I am placing with digikey so if I could find good one there that would be great. I might just give in and pay the shipping from partsexpress as I want to pick up some rca connectors too. If I wanted to use "snap in" style capacitors, such as the...

I dont know that it sounds different, I just know that I dont like it. I dont have an actual Beresford to compare it with but if someone wants to lend me a MK6 I will be happy to do so.

I finally got my hands on tubes. I ordered six but they are all different. Perhaps I can post them online and we can swap to make a set?

Can someone recommend a good 75 ohm bnc receptacle that I can purchase from mouser or digikey? I like the neutriks at partsexpress but I wont want to pay 20 dollars for two of them shipped.

Herandu, Thanks for that link. I'll try this before I totally give up on this thing. I just am not all that impressed with the sound out of the box. Again, this is a TEC 7510 but the pictures would lead me to believe it is EXTREMELY similar to the Beresford unit. Before I try to bypass the...

I finally broke down and bought a Zero. It sounds really nice as is to my ears. I'm going to try to address the low hanging fruit on the headphone amp. I didn't realize it uses 2 DUAL opamps. I wonder how they are configured exactly. I really want to either draw the schematic for this headphone...

I have spoken to Igor and he was not aware of the specifics of the mod21. Also I didn't see any pics of his Beresford with the lid off! I'm still hunting pics of the MOD21 if anyone has them or a MK6/4. Thanks

Thanks , Ill drop Igor a line or two. If anyone with a Beresford TC-7510 MK6/4 would share pics of their unit I would appreciate it.

Who is K Works? I bought mine from ebay. I would love to find out about that "mod21" and anything else out of the ordinary. I personally think it sounds OK as a DAC and a bit less than OK as a head amp in stock form. I am comparing it to my Music Hall 25.2's DAC and perhaps the TC-7510 doesn't...

Does anyone know what the MOD 21 is comprised of? I just purchased a "generic" TC-7510 and it looks identical to the one in this thread caps and all. I have some basic plans for it but I suppose the MOD 21 is the biggest bang for the buck from what I have read on another forum. I have posted...

Yes I have the latest versions of both Foobar and ALAC. All you do to "install" ALAC is copy the .dll to the components folder correct?

Thanks everyone! I just ordered my first panel and I'll let you know how it comes out!
