Dohhh!

I did that as well one of the first and easiest was to switch speaker terminal connetor from amp. I am trying to post a scan of the schematics as well as a picture of the cross over but having a little trouble. I will try image shack for the CO How do I post a PDF of the schematic? Thanks for your ideas and patcience.

I think the resistor value is too high or the inductor is a bit too robust and not the best choice or I can't read a schematic and messed up the wiring but Danny would have caught that.

Not sure what you mean by this, but I did switch just the tweater connects, then just the woofer then the tweeter and woofer I tried every combo on my Excel matrix that I created to make sure I tried every variation that I could think of, then I waited for the full moon and a glass of Port, same result....... I have a pair speakers I am working with so I kept one speaker as is for A/B'ing with no improvement in the B'ing pair and they still sound equally awful.

Your on! If you mean switching positive and negative connections, I tried that for both the woofer and tweeter with negligible benefits. I even tried voodoo but that didn't help either. So I am defaulting to someone smarter, which in this case is anyone reading this post. :'(

Unfortunately, I have neither but I do have a soldering iron, a screwdriver and a ton of frustration.

About six months ago I got swept up in the Insignia decent speaker for cheap craze and purchased a pair really cheap at Worst Buys with the intention of trying my hand at the Danny Richie Mods. My plan was to replace the mediocre speaker pair in my office with some nice looking and killer sounding moded speakers..........rrriiiiiight! http://www.gr-research.com/insignia.shtm Bottom line, they sound awful, worse than stock. I checked every resistor connection, inductor, and how I ran the connections. Out of desperation I sent the crossovers to Danny who hooked them up and ran a sweep. He found no problems, but they sound awful. I have fifteen hours of painful burn in and there is absolutely no improvement. I hate to throw good money after bad at this point, but at this point we are talking ego. I will not let this debacle end in defeat. Is there anyone out there who knows crossover designs who can take a look at the coaxial driver, inductors, and resistors I am using and find a solution? I will compensate you for your time. Thanks all. Greg

Napkins, both cloth and paper. may have been processed in bleach to make them white and no matter what there are some traces of bleach remaining which will effect the taste of wine strained through them. I know because I have experienced the after taste myself when trying this. Preferable to cloth would be some type of metal strainer or better yet decant the wine into a pitcher and scoop out the cork remnants with a spoon.

Interesting conglomeration, what style of music would you say? Thanks I will give it a try.

I am a big fan of the ECM and MA Records labels. I have found most of the recordings from these labels have great music detail and mixing, especially anything Todd mixes over at MA Records is exceptional in sonic quality. My dilemma is that both labels are very deep in talent and have many CDs available and I am reluctant to just randomly pick CDs without knowing what I am getting. Both labels have an eclectic roster of talent but some of it is just a little bit out there for me at this point and I would rather not buy a CD just to have to wait a while for it to grow on me. Any recommendations? What artists have you purchased and liked?

Agreed. There is nothing worse, in jazz especially, than a cranked up clipping album of music. Some engineers think buyers of CDs believe if it is loud and distorted, it's high end. Sheeze!

A Damascus chisel would be a real nice complement.....

I never in my wildest dreams ever imagined I would say that a hammer was a thing of beauty but .....that is impressive. How does it sound?

;) ;)

I would be really interested in your experience with the single driver build. My journey took a lot longer and exceeded my budget but I am pretty satisfied with the end result. If you get your build ratios correct and place the finished cabinets near the corners of your listening room you will be quite impressed with the lower order bass definition you can achieve. Good luck and please keep me/us posted.

...those are on my Fostex 166E's I have in a full range BLH arrangement and they fill out the mids and uppers very nicely seemingly adding detail and texture. The Seas have a great reputation though I have not heard them that I am aware of in a full range setting.... I would welcome the opportunity to do so some time.

Voltron, Deepak, Thank you for the comments. For purchasing information contact Boris at: [email protected] Boris is great to deal with, very responsive and knowledgeable. FYI the original price of $720 plus shipping was a mistake which they did not catch until after I had ordered mine. I suspect that they determined pricing in early 2007 before the dollar depreciated against the Euro. Their new stated price is $870. Kind regards, Greg

Excellent impressions Deepak. I wish I could spin some of my music for a comparo. The only experience I have had with the duos were in systems that I feel were not set up properly. Again, what amp was used, the SET one you mentioned earlier I suppose?

I think that is because Eddy Merckyx designed one of the op amps pictured.

I agree with Nate and Boomana on this in every way. I don't know but it appears lately, perhaps because we have somewhat of a reputation for not taking any BS but there seem to be a number of people migrating here to act out. In my opinion it is one thing to have uncensored dialogue on various subjects which I appreciate and value but it is another thing to have juveniles acting out to prove some type of point. That acting out behavior is a waste of bandwith and offers no value to me of any kind.

Well as of this moment, your only choices are Mladenovac, Serbia or Southern California. Equidistant actually to where you are now but not very convenient.

Boris Bhadinov, moose and squirl bahahahaaaa!

Thanks Aerius, you are very kind. Truth be known, it was your comment about the Karota amp and trannies that pushed me off the fence. I am glad I made the leap. BTW anyone noticed the "aux input" "line out" jacks on the back? It appears the Head One has a line source capability built in as well.

First A Little Background Trafomatic is a ten employee privately held audio, industrial, medical equipment and transformer manufacturer located in Mladenovac, in the Republic of Serbia. As noted in another thread, the transformers in the Trafomatic line are manufactured in house by Trafomatic but Trafomatic also provides transformers for Korato tube amplifiers, another audio manufacturer whom they declined to disclose, DIYers as well as power conditioners. Head One is their transformer coupled headphone amplifier employing two Russian 6S45P-E triode tubes and one EZ80 as the rectifier tube. A brief internet search found the three tubes costing from $45 to $90 dollars total. When I asked Trafomatic who manufactured the tubes in the event I needed replacements their translated response was: My question The 6S45p's are probably Svetlana or Saratov manufacture or are they really WE437A? How much current are the tubes running? Less than 50mA I hope. Their translated answer "Tubes are 6S45P-E, Russian military, manufacturer known probably only KGB. Every one (tube) has a stamp with OTK and number, so if there is a bad tube out, they know which one of the quality control people is going to end up in Siberia ;-) tubes run at 18-20 mA and are matched for gain. With such a low dissapation and construction they are expected to have a long life. The tubes are similar to WE437A but not identical". "The Head One uses the Alps pot, Rubycon and Capxon (sp?) for electrolytics, with a cathode bypass ..... plus WIMA MKC polycarbonate resistor that is a great match. Tube rectification with input L filter plus CLC filter for anode supply is used". One very useful feature on the Head One is the switch for 30, 100 and 300 ohm signal to better match the needs of a wide range of headphones. One difficulty I have personally experienced was locating amps that work well with my W1000 cans. For cans with 40 ohm sensitivity of the W1000s, Trafomatic recommended the 30 ohm setting. When I inquired as to how the different output values for various headphones was accomplished, Trafomatic stated that the output transformer was wound with multiple taps to allow for different settings and that great care was taken to minimize negative effects but they didn't elaborate exactly how this was done. Next A Little Music I have great familiarity with the CDs I chose for this evaluation. All CDs have very good sonic qualities and each emphasizes a certain portion of the musical range while highlighting the strengths and weaknesses of the equipment down stream. As source I used a modded Onix X99 with the Superclock upgrade feeding a PreSonus Central Station DAC and for cans my ATH W1000s. Cables were silver cable Eichman plugs built by some guy name Grand Enigma who no one has heard of I am sure. The selected CDs were: Tord Gustavsen Trio, The Ground (ECM) for the detail and texture of acoustic jazz. A good system can separate each instrument in its own space while the trio is playing. The decay of the piano notes and the absolute quiet background can be quite revealing. On tracks one and eight there is some cymbal work where the initial strike and exceptionally long decay of the notes reveals the detail capabilities in a system. Next was Mater Magnificat (ECM). The strings and chorale passages again require a fast and detailed presentation; there can be no middle ground in this recording. The female voice is very difficult to reproduce accurately and with realism in my opinion and Eva Bittova gives a beautiful and challenging presentation in this piece. The Bratislava Conservatory Choir leaps out at you as a group of individual voices not a mash of music. Sonny Rollins, Saxophone Collosus, a vinyl rip presenting great detail and head room on Sonny's tenor sax, the detail of Tommy Flanagan's piano and Max Roach's drums. I chose this CD because in theory an digital copy sourced from audiophile 45 rpm vinyl should have a large stage with lots of head room, and I was not disappointed. The quartet's music seemed to come from many directions both as source and reflections in a close microphone studio setting. Not the most textured recording for vinyl but still very organic and lively in my opinion. Brian Bromberg, Wood. The album name says it all. Wood is what he plays and what you hear. This upright bass piece has great detail and if you have had any experience with live string instruments close up such as a viola or upright bass, you will know what I mean. The detail of the notes on his passages are superb and very precise. In a weak system this CD can be unforgiving and the bass notes tend to bloat and roll off dramatically, but not here. Presentation, accuracy and decay are very, very good. In closing, I feel the Trafomatic Head One is very detailed and transparent yet adds no coloration to the music. The better your source the more of what is in the music is what you will hear. The sound stage is large, not the largest I have heard but very large and three dimensional. I have never heard of these odd Russian tubes before but they are a very nice musical match to the Trafomatic wound transformer. Definitely worth a listen........if you can find one. MOD EDIT - fixed your first link for you.
