Hi, I've been enjoying the HD800 single-ended for two weeks, but a thirst for hearing them balanced has become quite unbearable as of recently. So all you balanced HD800 users, please convince me that it's really worth it, since if something goes wrong, I won't be able to order a new cable...

Since my Dynamight DIY project is nearly finished, I'm starting to search for the ultimate low-cost balanced interconnect for this amplifier. My candidates are listed below. I would welcome any idea or recommendation. If you suggest any other cable, please keep the budget down, no more than...

I'm reposting this great news from AA and HFR: Some big news from David Chesky, owner of Chesky Records, this week. He says the label plans to not only start their new New York Sessions Jazz SACD releases on August 15th - but they now plan to release all Chesky Albums as Single Inventory...

...you start buying things like these two attenuator babies from ELMA . They are custom made, ladder type attenuators with extra 1x24 wafer (its purpose won't be revealed yet, I'll leave that to the great minds of Head-Fi ). They will be used in my upcoming balanced DynaMight DIY project, a...

Hi, I'm in the initial process of laying out things for my future project - uncompromising Dynamight . Everything went fine, before I started thinking about the ground scheme. I intend to use the standard configuration - PSU box grounded to the AC ground, AMP box grounded to the PSU/signal...

I would like to lower the gain of my PPA. So far I've been using standard gain value of 10. But with that configuration I use hardly the first third of the Alps' range with my Senns HD650 (listening at about 9 o' clock position). How low can I go with OPA637/627 combo? I know that OPA637 should...

Let me tell you my little story: I've been using Porta Pros with my iRiver iMP550 for a long time. They sounded quite good, little warm with nice detail. But their overpowered and bloated bass was driving me mad. After listening for about two hours my head seemed to burst. I partially corrected...

Just curious, if anybody got their discrete buffer for PPA from LaRocco yet. I know that there were a lot of people ordering it quite long time ago. But they are still dead quiet. What's the problem? Is Larry so busy that the buffers still weren't shipped or are you guys tight-lipped about...

It took much effort to save enough money, but finally they are here! Here comes my first impression: Right out of the box the sound wasn't so impressive (in comparison to my "old" HD600). The bass was a bit bloated and the highs were quite missing. But after several hours of intensive...

Here is my new toy... It is made of aluminium profile combined with brazilian cherry wood panels. It is powered from 20-cell NiMH battery (Sanyo 2100mAh) that lies under the amp board. The two bananas conectors are used for charging of this "monster". There is a possibility of using additional...

I know this is a bit subjective and component/rig/preference dependent, but I would like to know which op-amp do you generally prefer the most in your op-amp based amplifiers (META, PPA,...).

I know this is a bit subjective and rig/component/preference dependent, but I would like to know which op-amp do you generally prefer most in your op-amp based amplifiers (META, PPA, ...).

As said above, what do you guys think would be next logical step from my META42? Parts for both amps are nearly in the same price range so I'm interested which one sounds better. I love my HD-600 and would like to get the best of it. I know this may be a bit early to ask since the PPA amp is not...

Hi, want to build META (per Tangent's tutorial) and I would like it to suit my HD-600 the best. Any suggestions about picking the parts (e.g. op-amp, gain, number of buffers, etc.)?: I thought about this: AD8620 op-amp ALPS RK27112 pot, 50K EL2001CN (or EL2002CN does better?) - how...

Hi, I need a little help. I want to build the META but not decided which caps for C2/C3 should I take. My only source for parts is RS-components, so I settled down to these two types. So which do you think is better? Or are there any other caps from RS that I could use? Thanks for any income.

Hi, I´ve built a basic CMOY (according to Tangent´s great tutorial) few days ago. It sounds great from my PCDP headphone jack (Sony D-CJ01) but when I swap to the line out (which should sound better) there is no bass and too treble. What´s wrong with it? I´ve used the line out with my speaker...

Hi, I've finished my first DIY project: a CMOY for my HD-600. And it is better than I expected. It can really show up the power! But I still have some minor problems: 1) At 9V voltage it had quite problems with higher dinamic passages - I got distortion (maybe oscilation?). But when...

Hi, I´ve built CMOY today (per Tangents tutorial) and double-checked everything. It plays quite good and loud but the sound is coming just from the left canal (right---nothing). Any suggestions? I´ve used TLE2426 (and measured it - it splits the voltage perfectly), op-amp OPA2132PA, powered...

I recently bought Sony MP3 discman D-CJ01. I'm quite disappointed with it, especially with the long times before the CD with MP3 starts to play. What is the problem? It's so sluggish! It takes even 1 minute (!)to start playing and the swapping among the MP3 files is also horrible! But that...
