There are several reports from folks who say the screws are in extremely tight, and a few have said that the front right screw is the worst. I was for me, too. I tried to take it out first, but ended up having to drill it out last. The screws in my MPX3 were *very* tight--3 made that big...

Hope my pictures turn out right...I can see'm. Would ya'll inspect my MPX3 SLAM's configuration and tell me if you can, what transformer and capacitors I've got, and anything else you deem important. From its' operating behaviour, nothing seems amiss, but I'd like to confirm the unit's...

Sorry for the ignernt question. I couldn't find it with a search nor Google. I've seen this term used when discussing a headphone's sound reproductive qualities. Thank you.

I've got a couple of tubes that are really tight. I use a rubber jar/bottle top gripper (like the ones given out as complimentary "gifts") to remove them, and they're still a bear to get out. Wiggling doesn't normally make me itch, but these tubes go in and come out tight. I'm thinkin' of...

Hello All, I have an OPPO DV-970HD and a Sony SCD-CE595 5-disc changer. The Sony's pretty good for the price, but the OPPO flat kills it in regular audio CD scanning--the comparison is akin to Bambi vs. Godzilla. The OPPO's mids are clearer, the stage is broader and the sound is cleaner--each...

Moderators please delete if this is another dead horse. I ordered a single 2c51 adapter from Singlepower on July 8, 2008. (I didn't visit Head-Fi for > a month and didn't see the cautionary threads beforehand.) My CC was charged on 7/10, and the transaction "posted" on 7/13. The total cost...

I modded my D5000's. I was religious about following the directions, and I completed the entire modification--it wasn't just a partial mod; it probably took me 5 hours. I did the mod out of curiosity--chasing the 'holy grail'--I thought, for the minimal financial expense and time, the...

I've never heard another headphone amp aside from my own. What's the difference between SS amps and tubed amps? Everyone says "tubes" are warmer, but I've heard some damn thin tube combinations... the EH 6sn7's sound pretty tinny to me, if that's an 'example' of SS sound....

Hey Guys, I ordered a couple of adapters for an MPX3 on July 2. My credit card was charged on July 10, and I've received nothing--no correspondence, no merchandise. How does Mikhail usually ship--UPS, FedEx, DHL, or US Post Office? Who am I waiting on? The phone goes unanswered when I...

Quote: A few words regarding the Mullard CV181 (ECC32): This tube is highly sought-after. BUT, it is NOT a 6SN7. It is an ECC32, which is NOT a drop-in replacement for 6SN7. As mentioned earlier, the current draw for this tube is 50% higher than a 6SN7. This will blow most power...

I'm driving a set of Denon AH-D5000 cans (the infamous "low impedance" hurdle). Just when I settled on a Mullard ECC32 and two Tung Sol-D 5687's, I got bit; I gotta stop reading this forum... I'm ready to try acquiring a 2C51 adapter and pairing it with a couple of 6BL7GTA's. However, I'm...

BRAND new to all this...some recent posts have me confused and very unsure of my understanding. I bought a used MPX3 SLAM and an assortment of tubes; 3 of them are a Mullard ECC32, and 2 Tung Sol D 5687's (or so I was told). Power Driver Gain Output I've seen these four words used to...

Hello, I'm just getting into headphones and HA's. My toys have arrived and I have some really dumb questions that I can't find answers for with 'search' or Google... 1) Is it bad to remove the headphone jack with the amp turned on? Can I plug in headphones after the amplifier has been...

Hello, I'm as unfamiliar to headphone amping as a pig in a shirt. I'd really like to hear what you all would recommend from your experience, for my combination. My music is probably 60/40 classical/rock. The equipment match I have is a Singlepower MPX3 SLAM and a low-impedance Denon...

Hello All, I've been reading a ton of posts on this site and I think I've narrowed my choices down to two. I'm in Podunk, USA... the only way I'll see (or hear) the qualities of a headphone amp is to buy it outright on the blind. A 500-mile drive wouldn't get me any closer to seeing a...
