I have not heard them all but...   M3 for ability to drive most headphones easily and smooth tube like sound.   DV 336SE but SKYLAB has never been wrong...ever. Just teasing SKY.

I believe the Opera attempts to emulate a warm, round tube sound. It does so at the expense of smoothing detail. Sharp definition and detail is a strong point of the Red. The synergy between the Red and Senn 650's is very good, as is the synergy between the ASL MG HEAD OTL MKIII and Senn's...

Can you describe how the Opera sounds with the HD800 compared to the Travagans Red?

Yes if you have stereo output from your soundcard. I was looking at this cable for my Presonus Central Station and have the same cable brand that is TS to RCA terminated.

Thanks for for taking the time to post this review as soon as possible as I am sure many have been waiting. Well written with good comparisons so we get a relative ranking of sound quality which is hard to do with the written word. When did you find out the chipset on the E7 amplifier was...

I have written many reviews here and appreciate your honesty. It is obvious to me you care about our community enough to take the time to post reviews and updates and I appreciate it. The new Fiio is one of the most anticipated portable amps to come around here. There may be a communications...

I don't get this on mine either. However some others have commented that this is an "undocumented" feature. They claim there is a boost in both treble and bass when the bass switch is moved halfway between off and bass boost.

I have to be honest, that while the T3 is cleaner than the E5, I really have to be seriously listening to hear and appreciate that cleaner difference. And depending on the 'EQ' setting you use on the E5, it can sound a bit fuller and warmer than the T3, to me. The 4 gain settings of the T3...

Here is another vote for the ASL MkIII tube amp with the Sennies: One of the best synergestic pairings I have ever heard and I have heard a bunch.

Is there any evidence that, in fact, Denon HAS changed the D2000 cable over to the cable that is used in the D5000? Perhaps those who got the "stiff" older cable received old stock, which is what I want to avoid.

Does anyone have information regarding how to tell if you have the "new" Denon D2000 or if they have an upgraded cable?

"....a maxxed out PPA gets no love these days." This is a great thread. It seems like a short period of time ago that one of the best choices was a Pimeta from one on a few builders on this site. Life has gotten much better with competition from the China builders. These days I am...

I believe drarthurwells has taken the time to post detailed instructions on how to replace a blown mosfet. This is a common problem with the PH-12 due to removing a tube without waiting 24 hours for ALL the power to dissipate. I use my PH-12 all the time and it has proven to be very reliable...

Hi Pat, Looking forward to your experienced review. Glad to see you still having fun and enjoying this hobby and music. Once one gets used to the different perspective of the ER-4S soundstage, they become keepers for many trained ears on this site. As with many IEM's, I think they are...

double post

I have had problems with the Xtra X1(not the Xtra Pro model) battery as well. After looking exhaustively without success, Ebay seller jasmine_chine came to the rescue. He has provided great service for me over the years with good communication and care for his customers. Email him at...

I brought it to my local Interstate and they did not have the battery and said they could not build one. Any other ideas on where I can get one of these: ImageShack - Image Hosting :: xtrax1battery.jpg I believe it is a 2 x 3.7 volt mah lithium poly battery

My Xtra X-1 amp has a problem. It works with the battery removed and the charger plugged in, but when I connect the (dead) battery the unit shuts down and the battery does not seem to charge. I like this amp but cannot find a battery for it. I emailed Jasmine Chine and Uncle Wilson at Jaben...

I like this amp but cannot find a battery for it. I emailed Jasmine Chine and Uncle Wilson at Jaben but they no long sell the amp. The battery I have for this unit has no markings on it and I cannot locate a replacement after weeks of searching. I think it is a 2 x 3.7 volt 500 mah lion...

Thanks guys. Please keep your ideas coming for what home amplifiers you would like to see added to this comparison. I have some time to spend on this after I finish the project I am working on and plan to update this review with more amps.

Awesome compendium and detailed as usual. Very interesting to see where the PPX3 resides relative to the WooAudio 3+. Thanks once again for your hard work saving countless people time and money not the mention making our hobby more enjoyable. In Skylab We Trust. Tom

Glad to see you bring up the Central Station, Uncle. I still really like mine after countless other SS and tube amps. It has a burnished warmth that offers great synergy with the Denon D5000. Incredible build quality, state of the art preamp, DAC rivals $1000 units AND 2 great headphone amps...

The Travagans Red is ranked and compared here: http://www.head-fi.org/forums/f5/rev...ns-red-266118/

Look at the Purity Audio Caliente for a solid state amp with the 701. If you are having trouble getting too little bass from the 701's this amp sounds as if it were voiced to work with this headphone.
