What op amps would go well with Senns?  Currently have a C&C XO with an OPA627 but find it a little too warm and up front. I'll be using it with HD600s and need it in a DIP8 package @ 7V (Brown Dogged SOIC OK as well).   Been looking around and the AD8620 seems to pop up the most.  Also...

Anybody get any fakes from UK sellers so far? I believe the previous consensus was to beware of sellers from Asia but starting to see more and more popping up from UK at low prices from sellers with >99% with 50+ feedback.   Sorry in advance if this has already been discussed. Only browsed...

I recall seeing an ad about a motion activated CD player a few years back.  Anybody happen to know the model or even better, a link to the commercial?  The concept is similar to the JVC NX-TC5 but instead of tilting, two glass doors covering the CD drive open.   I'm hoping to use the part of...

@majkel:  Compared to the 49860, I believe your comments were that the 4562 was smeary and the 49720 was bland.  I wonder if the 4562 and 49720 are manufactured at different plants. On a more detailed note, since the 49860 has a wider operation voltage range, did you ever try running it in...

Looking to buy some opamps for rolling then stumbled on a thread with people saying that the three are the same thing.  Some vendors market them as the same as well. LM4562 and LME49720 are the exact same part... just different model stamped (stated by an ex-employee) The LME49860 is just a...

Anybody happen to know what the gain is on the "High Gain" mode?  Thinking about swapping in an OPA2228 but won't be any good if the gain is too low.

There seems to be a person selling out of China for pretty cheap claiming that they are used.  ie 2x AD797BR for $8.50 http://cgi.ebay.com/2PCS-AD797BR-Mono-Op-amp-Ultralow-Noise-/350410104095?pt=LH_DefaultDomain_0&hash=item519611dd1f   Their rating is quite high (> 1000 feedback @ 99.7%...

Thinking about rolling the opamp on my C&C XO but not too sure as to what will be compatible.   Lots of threads on opamps but not many giving power ratings. Some opamps I am currently considering are: LT1364 (Recommendation from Avro-Arrow) TLE2142 OPA2111 OPA2227 OPA2228 (Will the...

Although build quality and comfort are also deciding factors in purchasing a product for me, sound quality is definitely the number one item on my checklist. A set of cans that is transparent with good instrument separation and a wide soundstage would be my preference. On a more personal...

Quote: Originally Posted by wali I have posted this before, but once again. check out the difference between HD600 and K701, and their impedance vs frequency chart. The graph is self explanatory but it shows that HD600 will perform best in 300-600ohms impedance setting, while...

OP updated to answer questions but to re-iterate: "Source will most likely be from my AMP3 Pro.1 (Will the hiss affect things?) or Fuze v2. I can consider my laptop but don't think a USB powered DAC/AMP will have enough juice and if powered externally, the idea of yet another adapter doesn't...

I know this is blasphemy but can't really afford much at the moment. I promise that I will get something more worthy once I get my career going (ie just graduated with no job and got tons of student loans to pay back) Back on topic, trying to see what's available in the used market for ~100...
