    headphone warm-up time?

    Is it just me or do headphones seem to need about 5-10 minutes of playback to "warm up" and really start to sound good? It seems to me (at least with my cans) that they don't really sound all that great until they've been playing for a few minutes. At first I though it was in my head, and...

    Is it true that a portable amp can boost the bass on a pair of headphones?

    I ask this question because I really want a pair of basshead headphones, yet I want the mids and highs to be warm and clearly bought out. BTW, I like to listen to jazz and contemporary music, as well as hip-hop and dubstep. I know that when buying a pair of bass-heavy headphones, the quality can...

    6SN7--continuing on a new thread

    I was astonished by the number of posts on the 6SN7.   As a designer of high-end tube audio gear (coffmanlabs.com) I thought it worth sharing my experience from the design side. YMMV  And just to make it clear--I do plan offer some of my products with the 6SN7; I have around 4,000 to 5,000...

    Mysterious 12AU7/ECC82 Vacuum Tubes

    I have recently taken the risk to purchase NOS vacuum tubes from a well-known auction site. While they appear original and the sellers have extremely good reputation, I cannot find background information on the origin and quality of these tubes.   In my previous research, the only...

    General questions about Tube amps...

    can I use retro amps?

    I was wondering, how about I get myself a retro amp like Yamaha or Denon or something for a few bucks from a garage sale and use them to drive my headphones? these retro amps weight a ton and should have pre amp / dac and everything built into them, right? So I can just take a 3.5mm to RCA...

    [Question] Why don't people separate pre-amp with headphone amplifiers?

    From what I know, in speaker systems the separation between the power amp and the pre-amp is strongly advocated, as it further separates the initial signal and the final amplification, forming a cascade of amplification, giving a cleaner sound signal with lower noise and interference and...

    My Headphone Amp Design!!!

    I needed a headphone amp to drive my pair of headphones, not like they needed amplification in terms of SPL but in terms of SQ (Sennheiser HD555 with foam pad removed and damping added on the surrounding walls around the drivers).    I wanted to design my own amp that would upgrade the sound...

    Question-switching between multiple amps

    Hi folks,   I'm afraid this could be a dopey question, but I am prepared for any humiliation and ridicule coming my way :-)   So, I would like a convenient method of switching a source between my three amps other than pulling the L/R RCA's and moving them between amps.   Is there any...

    Alternative to stock HD25 cable in same (sub $50) price range

    Is anyone but Sennheiser making cables for the HD25 that are not super expensive? I have little belief in gaining any significant sound improvements by using $100+ on a cable for such a headphone, but the stock cable is really, really bad.   I've owned two, and both have had problems with...

    Completely new to Amps. Are they actually worth it?

    I've been looking at headphones for a while now, and all of a sudden amps start showing up. What are they, how do they work? Do they need batteries or external power? Are they actually useful for portable devices?     Sorry, lots of noob questions. Ignore this post, or direct me somewhere.

    Good/Cheap headphone amp for Sennheiser HD 439

    I recently bought Sennheiser HD 439's and I feel like I'm not getting enough bass out of these. Would a decent headphone portable amp (pocket sized maybe?) be of any help? Black friday's coming up so I thought might as well.   Also a modding guide would be cool too, never done any of this...

    Would purchasing a headphone amp just for Spotify make a difference?

    I have a premium account on Spotify (320kbps), playing from my iMac, with Audio Technica M50s, but would a headphone amp boost the quality?

    Does anyone know of a high-end headphone amp that has a "mono" switch (i.e., that will combine both channels before outputting to the headphone jack)?  I recall seeing one somewhere on this site, but can't seem to find it again, and I wasn't having much luck searching this forum (but I may not...
