At the moment I use D2000's with a MMH and a Bijou and I'm looking to trade or sell them to fund a more appropriate low z DIY amp.

 

Thanks again

Basically any amp that is not an OTL.

hi imay sound dumb  but im a noob, but yeah... would a regular headamp like "little dot etc..." produce a better sound than a regular Receiver "headphone out"? i have 2 receivers "hrt5650 and sx-780" and a uDac2... i dont have a headphone yet tho.. ill be buying ultrasone 750, 780 or 900 in the near future.. but im just wondering just in case ^_^

Simple answer - it depends on headphone amp and receiver.

and the headphone

I recently purchase one from Madcap Audio based in Singapore with reference buffered design. Have his own circuit board too. I then upgraded the opamp to Muse02 with OPA2107. The combination is really awesome. :)

 

You can order a kit or just the PCB.

Found another one: the World Designs HD3S, a single-ended pentode design it seems.

 

Also: *bump*

I have the original version of that amp: the World Audio Designs HD83. Its the same amp, but the newer one has a better method of switching the secondaries.

 

The amplifier is triode/triode-strapped-pentode, with a VERY neat feedback arrangement. 

 

This marks the 4'th time this amplifier has been mentioned on head-fi.

No kidding, I discovered its existence last night, searched Head-Fi to check if it was mentioned, and all I came up with was a '01 thread! It's even worse than my Castanet: at least I wrote a review of the latter.

 

So, how big/heavy is it?

We've got a new one! The Bottlehead Smack WOT (With Output Transformer). It's in the list, and you can find the information here: http://www.bottlehead.com/store.php?crn=224&rn=455&action=show_detail

The Smack sounds very good - we've been needing a reasonably priced transformer amp. I am sure it is up to Bottlehead's high standards and I hope it's a big seller for them.

Version 2.0(PCB as pic) was sold out, seller told me newer version 2.8 will comes later.

 

Kit price is RMB$250, add RMB$90 for chassis. (Version 2.0 w/o shipment)

 

110V transformer is available for purchase.

And the Ventus EZ with Opamp input stage instead of discrete.  I built one of these a while ago and it sounds excellent.

I just ordered a WAD HD3S after listening to a friends with some Audeze LCD2s at the weekend.  It is a match made in heaven.  Natural delicacy and power combined...  No complaints about low frequency bias with the LCD2s with this amp.  We compared the WAD with a Lehmann Black Cube Linear, Musical Fidelity XCAN V2 & V3 (both with PinkFloyd mods and aftermarket PSUs) and a FIIO E9.  We compared the LCD2s with Beyer T1s and a pair of AKG 701s..  We both agreed that the WAD was the best amp on all of the headphones tested and the WAD and LCD2s were the best combination by a considerable margin. Heres a photo (The BCL didn't come out until after the photo was taken - sorry).  The WAD is the black amp with a silver front on the left, the XCAN V3 the amp with the headphones on top.
