I currently have a massdrop Koss ESP/95x. I got it a year or two ago. It is my first electrostatic headphone and I have taken quite a liking to it. Recently the power cord became frayed and it is out of commission atm. I was going to order another power supply but then I began to seriously...

So I just pulled the trigger on a Wa7 fireflies unit but I got a good deal from somebody local and I have an additional $400 to spend and can have narrowed to either a new Koss ESP 9x from massdrop with the power supply for or a second hand Focal Elear (both are priced at $400). Looking for...

So with the plague confining everybody to isolation, even though I am still working 2 jobs (Healthcare provider and college instructor moved- to online) my vacation was cancelled and I find myself with extra time and some extra cash so I decided to add a new amp and was considering a 2nd gen WA7...

I am struggling with some concepts and was hoping somebody could help - I have an amp with "jumpers" that allow for varying levels of output impedance. Why would I ever want to use the higher impedance settings - doesn't that just decrease my power output and also make the 1:8 rule of thumb...

I am fairly new to Jriver and recently set up Gizmo on my android phone. I went through the port opening etc and all was working fine. Went to use it yesterday and could not connect (either via  wi-fi or 4g streaming) from my office. When I got home I found out that I can connect remotely when...

I have had a scratchy volume pot on one of my amps for a good while now, akways in the left channel and only when turning the volume knob. I always assumed it was from contacts on my pot but I recently noticed the tube was tilted just a bit and I re-sat the tube in the amp and lo and behold the...

I was wondering if changing opamps changes the power (volume) that an amp puts out. I have a DAC with a headphone amp and the headphone amp section has switchable opamps. The volume with several of my headphones is less than optimal so I was wondering if changing opamps would increase the volume...

I used to wonder this and see it asked all the time so here is a link to a  page that will answer that - it shows you how to calculate it based on what info you have and since the math can be tough there is a d/l spreadsheet that will do it for you. Good page to bookmark until you get a feel for...

So I am about to do a massive overhaul to my current pc which may change the audio situation somewhat. Currently I run a Phenom II and old AM2+ mobo with ddr2 ram.   Anyhow I had been running a gtx 580 gpu and using the HDMI audio out to feed my AVR. From there I can either a) listen to it on...

So I recently installed Jriver as my media player/server and am unable to play M4p files. I have quicktime installed (and selected as the output device (renderer? engine?)) but there is no sound.   A couple of background issues. Jriver has searched my network of pc's that I have cobbled...

I am sure this is easily answered but I have spent too much time surfing for an answer so hopefully one can help me. If I ourchase Jriver can I install it on multiple pc's I own or is the license /DRM only allow installing on a single pc? Thanks - JK

I have a few questions re ASIO, WASAPI, DS please help me understand.   I understand that you need to use WASAPI or ASIO for DSD but for standard PCM or bitstreaming you can use any of the three.   Hydrogen Audio claims that the three are indistinguishable in terms of audio quality and sound...

I ordered a cheap windows 8.1 tablet (since they were out of stock in local store) since I have a few things I would like to do that my android tablet isn't really suited for. Previously I gave up and traded my Fiio dac/amp because I couldn't get the USB OTG cable to work nicely with it or my...

I have a chance to get a "lot" of audio items for $120. The most intriguing items are a Sony SACD player and velodyne s-1200 subwoofer. I know the subwoofer is adequate - good but not great but having missed the SACD flash is it worth it to grab this for the player and sub . Other items in the...

Went out to my car to go to work this am and found it ransacked, they got 3 headphones (AT M50, Sennheiser 380, Skullcandy Aviator) and my Asus tablet. I have android tracker/lojack installed on my tablet so hopefully as soon as they turn it on the the police can get them and just maybe I get my...

It seems like a distinction in many headphone amps is whether or not it has an op amp. I understand what an op amp is but not why it is a better or worse choice than an alternative. BTW being a long term 'speaker' HT guy moving into the world of headphones and related items I feel like an idiot...

I was considering one of these three as my next set of cans could somebody please give me as best a description as you can of the differences/similarities between the three and relative comfort of each - many thanks JK   I would be looking for a more neutral sound as my current 'fun...

I recently invested in my first tube amp and it has jumpers to select between either 10 or 68 ohm resistances on the output. I am not sure I understand which I should use. I have several sets of headphones of 32, 45, and 250 ohm resistances (M50's, se-a1000, dt990). I don't really notice a...

Currently most of my headphone use has been with my AVR ( Onkyo TX-NR905) which has Burr-Brown 192 kHz/24-Bit Stereo DACs (PCM1796). I have a tube amp on the way I plan on using but it does not have a built in dac so what I was considering was using the dac in my AVR and then using the analog...

I am interested in entering the world of tube headphone amps and had a few questions before I make my first purchase. I am looking to make an inexpensive yet informed purchase and have researched a bit and am left with the following questions   a) How is it that some two channel amps only...

Paradigm has long been a favorite brand of mine when it comes to home audio. My 7.1 HT is Paradigm with a HSU subwoofer. I see that Paradigm is now making headphones - anybody listened to a pair and if so what are your impressions???

I went to discuss a certain headphone in it's thread and when I did I got this message     Have I somehow unknowingly done something wrong ? I can still post on other threads.

So I went to look at some beyerdynamic the other night and I prefer open so I was interested in the 990's but as it turns out they did not have any 99O in stock, they only have the 770's and so I listen to those and while very good they are just a tad bass heavy but being closed I expect...

I may be getting a Music Hall 25.2 DAC / headphone amp but have seen conflicting reports so I could use some clarification from those in the know. If I am to understand correctly the DAC uses a tube for conversion along with a TI chip. I assume this is a hybrid situation and then passes that...

I am an audiophile that has been mainly involved with full size home audio in the past but have started to get into headphones and have a few questions about beyerdynamic headphones.   Currently my headphones are Pioneer SE-A1000, AT-M50's, and a pair of cheap Sennheiser HD200's as I have just...
