While there are a few threads for AmpsAndSound amps in the Full-size Amps section of Head-Fi, I felt each of these components deserve to be represented here in Summit-Fi. In order to make more sense, I'll do this review in chronological order. And sorry up front if you feel I'm too verbose...

Anyone actually know what they are working on next?  

Ever since David went MOT, it's just not the same without his regular polls and comparison threads posted all over Head-Fi.  So here's one to bring back the fun!      I selected "I'm fully satisfied with no itch to change anything, but will try a new componant if it get's lots of great...

  Due to some bad experience trying to get a couple of other SinglePower amps fixed and made 'safe', I decided not to try and get my Extreme updated, but instead get a new and better amplifier. Of course deciding on an expensive amplifier that I can't audition can be a slow and difficult...

  After reading in the Edition 10 thread a week or so ago about the treble problems some people are experiencing with that headphone, someone suggested using an equalizer to see if that would fix the problem.  A number of people stated they would never use an equalizer, and some even felt...

As being one of the lucky few who has heard the Apex Pinnacle at length, I would first like to thank Todd at TTVJ for loaning me the amp.  And I just happen to be a little luckier than most, as after I received the amp, the next person in line to receive it told Todd he couldn’t accept it before...

I know several SinglePower amps can do 6sn7 inputs and 6sn7 outputs.  And my question comes due to the increadible music I heard out of the Maestro-based amp with the correct(!) matching of 6sn7 tubes in it - some of the most emotional music I've ever heard.  I never could get the MPX3 to sound...

Has anyone compared the vintage Mullard xf2 EL34 to the new Groove Tube EL34M, which is supposed to be a replica of the original xf2? The Groove Tubes sound great. Especially at $100 for a quad. But I'm wondering if spending ~$400 on a quad of vintage xf2's would be worth the extra cost...

For those who find the JVC HP-DX1000 headphones to be too dark and somewhat bass-heavy. Or find the soundstage to be too 'expansive' or maybe rather distant and have somewhat of an 'empty-hall'-like sound. Or want a more involving type of sound. And you don't mind playing a bit with a $900...

I just decided to do all my reviews at one time, so they're all put into the same context. Sorry this is so long. What we listen to are not headphones, or amps, etc., but complete systems. And every component of the system contributes to the final sound and feeling of the music in some way...

This is a very short 'review'. I just wanted to share my thoughts about my cable upgrade for my Ultrasone Edition 9's, because I've read in a number of posts about recommendations from Ultrasone and the maker of certain solid-state amps popular with Edition 9 owners that these headphones don't...

Ok, I have a SinglePower Extreme and SinglePower MPX3 and am loving them. I currently have a 6SN7 as the gain and 6BL7GT as the power tubes in the MPX3. And a 6414 as the gain and 6AS7G as the power tubes in the Extreme. The 6414 gives me great dynamics, impact, and frequency extention...

I'm having a hard time listening to my 'normal' cans now, and I'm wondering what others think. This is a poll for those who own or have owned an Ultrasone S-Logic headphone and therefore have had time to really adjust to the difference. If you've only heard one for 15 minutes at a meet, that...

I love my new Ultrasone Edition 9's. While at first I thought they would crush my head in, they are now just barely tolerable. I've been pretty much trying to bend the bendable plastic section in the middle of the headband before every use, but I still need more relief. Have any of you Edition 9...

There seems to be about 20 to 1 amp and DAC manufacturers compared to serious headphone manufacturers. They also seem to come out with new amp designs every few months or so. Are headphones that much more difficult to design and manufacture? SinglePower seems to be having great success making...

I wasn't sure if this is a headphone question or an amp question, but decided it was really a headphone question. I recently acquired a HE60 and HEV70. While I haven't listend very long yet, the sound doesn't come close to my L3000\Hornet combo. I've read many posts that the HEV70 sucks. And...

Has anyone removed the metal grill that's between the drivers and your ears? Did it sound better or worse? Is it even possible without ruining the headphones? I haven't yet tried to open the headphones to take a look. Anyone know how to do that?

Maybe this has been discussed recently, but I couldn't find any thread about it after a few searches. I'm amazed at how many new threads are started daily. There are so many that the few threads I may be interested in are quickly moved to page 6 and beyond, and they're fairly easy to miss in...

I recently purchased the AT-L3000 and AT-HDA3000 from mbratrud. You can see his review of them here: http://www6.head-fi.org/forums/showthread.php?t=128958 I’ve been listening for a week now. For a little of my history, I started with a Sony MDR-V6, which I still have. Owned a pair of B&W...

Anyone know if there are people still upgrading the Melos SHA Gold pre-amp? The www.melosaudiorestoration.com site doesn't seem to be online anymore. Thanks, bdh

Why is it to get better sound than the DT770, A900, or K271 do I have to spend a ton of money -- and for some cans that have plenty of short-commings? It seems like a great opportunity for a headphone manufacturer to supply a willing market that isn't being filled yet. . . . And if any...

The high-end IEM's already have up to three drivers now. Why don't some full-size cans have at least a seperate tweeter? It could be mounted just forward of the mid/bass driver -- in a very wide 'V' configuration. The tweeter would be very small, so it wouldn't have to make the cans a lot...

First, the problem: I recently bought a Darth Beyer DT770 from Headphile, because I couldn't stand the fatigue of the Sony V6's I still had after selling my R10's. I also bought a Grado 325i for home use. The 325i has the musicallity and slam I wanted - it could use more low end for my taste...

Rate your Tinnitus (or lack thereof).

First, I received the Emmeline HR-2 last week. I plugged in my Sony V-6 and knew it had the magic described by markl in his review. I compared it to my Melos SHA-Gold and the headphone-out of my Marantz 63SE CD player. Compared to the others the Marantz output had a closed, muddied, and...
