Thanks for the reply. I guess I was thinking the isolation would somehow be more elaborate than the LC filter. Although it makes sense that the 'isolation' can only go so far as all the outlets in the box eventually lead to one outlet in the wall.   I somehow expected more - although the...

Can anyone explain how the outlets in the picture below are isolated? LC Filters for each receptacle?   I took apart three separate units from two different companies using the same licensed technology and they are all the same. I bought these directly from the companies and paid extra for...

  Quote: Not just about power... but with the review below, I will not bother with a Phonitor until I get some high Z headphones. Very happy with my amp for low Z 'phones.   http://www.head-fi.org/products/spl-auditor/reviews/6451          

Impressive and mature. That's a good start.   Quote:  

Wow this blows. I've been thinking about getting some LCD's since I got my Meier Classic amp.   I can understand boutique products having more 'minor' issues than stamped out mass produced line products, but that is no excuse for piss-poor customer service.   The only affiliation I have...

"Welcome to Head-Fi. I'm sad about/over your wallet."   Makes enough sense to be understood I think.   Quote:  

Translation below (I'm from Germany too). Many things in German are implied, and not explicitly spelled out so you will see some parentheses. Also, this is as much a review of the LCD3 as of the Classic. There are two schools of translation: the absolute correct which is directly related to the...

Mind temporarily blown.    I do believe I see an integrated sprinkler system in there.... all of these elements together equate to money on top of money on top of money.   This reminds me of recessed edge track lighting - which I've always liked. It's much easier to do from scratch though...

The real question is what's your budget (if that's not too personal) and what exactly does your BF already have? Stax-009 headphones are $5,000 for example - but are supposed to be the best out there ATM. With the Stax you pretty much HAVE to buy a high-rent headphone amp as well (another...

Quote: Where are the spec's for the Creative Labs X-Fi Recon3D?   SNR, power available, output impedance, power source, P-P Voltage swing, component types, cross talk, etc? It looks interesting but based on my experience I would be very hesitant to recommend such a thing for 701's...

AKG K701's are amazing - especially for the price.   Unfortunately you need some pretty good amplification to really make it sing!   The 105dB/V sensitivity is misleading. Normally, you see sensitivity quoted in dB/1mW. If you use this unit of measure we're talking 93 db/1mW.   A...

Quote: LCDs, and other low impedance headphones are what the Classic can drive best simply because it puts out more Power at lower Z. Double the Z, half the power with this amp. Double Z again and half the power again. It is a stable relationship throughout the range.

  Quote:   Almost. All month (December and until yesterday) I listened to the Jazz. Today I got home from holidays and had a Corda Classic waiting for me in the mail.   I will write a review once I get more time on the Classic but initial impressions are... WOW. On vacation I...

  Quote: I can believe this... but... at low Z there is not "much" power. Wonder if the experience would be enhanced with more Power @ 25 ohm.   Also, I read on here that many people with low Z headphones were able to hear a distinct buzzing sound with the Phonitor... if that's not...

  Quote: Okay on the first two parts. But... let's think further ahead. How about a time when headphones are only in museums... When sound is projected directly into someone's head for example. How about a whole recorded concert with an accurate representation of the actual sound stage...

  Quote: Now we're cooking.   I can think of literally a hundred things we would need (not all physical, some methodical) to test, but still can't say if it would be conclusive after all that work. Would love to try, but I don't get paid for things like this, rather use that money...

Hahahaha, that's hilarious.   I have not once stated my opinion prior to this post right here.   Yes, I might have a bias... in that I think burn-in perception might be real from personal rather unscientific experience.   I was merely commenting on the lackluster data collection...

The DS does look very well constructed. But what I'm talking about is simple: drilling straight holes, and lining screws/sockets up properly. It doesn't take a lot of money to do these simple things... I recently bought a much less expensive Meier Corda amp for my father... it obviously is not...

Does hifiMan have quality control issues? I am considering buying an HE-6 or similar but the EF6 in particular doesn't seem very impressive for that amount of money. Maybe I'm being unreasonable.   Just that... for $1300-$1500 the EF6 looks poorly constructed, and that's just the outer case...

  Quote: Got it. Is it safe to say the problem with most SS amps is lack of current delivery for something like the HE-6 (low impedance, very low sensitivity), regardless of Power?  

Quote:   It's all about power in the end... current and voltage to get you respective watts. If you don't have the current, or don't have the voltage, you're not going to get the power you need. This is of course over-simplified, but there is a stable relation between the 3 elements.

Quote: Agree with some of the above. Nothing here is rigorous enough to be evaluated properly. I would say please believe what you will for the mean time. If anyone lived near me I would invite you guys over for some Christmas special Corsendonk beers.   Quote:  ...

Does an EF5 adequately drive HE-6 phones? The EF5 supposedly delivers 2 watts per channel into the 50 ohm HE-6 impedance....   If the EF6 or something similar delivers 4 - 6 watts into each channel, would this not be enough to push the HE-6 to it's audible limits? I'll go off in a corner and...

Quote: From an experimental point of view nothing on this board in regard to burn-in is solid enough to even attempt to submit to peer review skewering. I will leave it at that for simplicity.   Note: that doesn't mean something is wrong, there is just nothing rigorous enough to be...

I guess I haven't been on this board long enough but I'm going to shoot anyway: why all the hostility, back and forth, and bruised egos?   If you believe in burn-in fine. If you don't, also fine. Why try to prove your view to "non-believers" whatever view you hold? Is this a new religion...
