Many thanks for uploading this file. I could not find a alternate download link anywhere.

I believe the dacmagic plus is fully balanced. Someone correct me if I am wrong.

Hi Everyone,   Here are my pictures from the meet. Till next time!                                          

Grant fidelity is in fact selling matrix as well. Looks like they setup a matrix canada website separately. Website: http://www.matrix-digi.ca/

I think the last mentioned introductory price from Yulong was 12,800rmb (around 2100 USD). Higher priced compared to the DA8 but not double. I'm sure this will probably change closer to the official release.     Quote:   Any chance you know if the A8 uses the discontinued K170/J74 JFET?

Agree with project86. The headphone output on the front is definitely better for most low impedance headphones.   A few pages back I measured the output impedance of the tube out around 150 ohms. This is too high for most low impedance headphones even if damping factor is not a issue ie...

I've owned the Grant Fidelity PH-6(Yaqin PH-5) headphone for about 7 months. It was one of my first headphone amp purchases after venturing into the headphone hobby. Overall, it is a nice entry level headphone amp for the money. This amp uses a hybrid design of tubes for the pre-amp stage and...

project86 - First of all, thanks for the review. The Yulong A18 is one of the amps I am considering at the moment. One area of concern for me is what you described as "Class A hum" driving certain low impedance/high sensitivity cans. Have you discussed this potential issue with Yulong/Grant...

salinmanji, which province are you located? I would suggest looking at local electronic component stores. ie. active electronics, MRO electronics. Locally in Calgary, Alberta I have seen regulated 24v for little as $10 to $15.   http://www.mroelectronics.com/mro/product.php?id_product=923

I have both SR325is and PS500. The 325 is definitely brighter sounding while the PS500 has stronger mid bass punch and less aggressive treble. IMO it really comes down to preference. I use to dislike the 325 which grew on me over time. IMO the PS500 is a better all around performer matching well...

That is a capacitor, not a resistor. Looks like it is used as a power supply bypass capacitor. Typically bypass capacitors are integrated into the circuit to stabilize the op amp. I doubt there would be much if any benefit in adding the additional bypass cap to the LM4562. 

I'm very interested as well. Missed out on "the wire" awhile back.

AKG seems to want a piece of the celebrity endorsed headphone market that Beats/Monster pioneered. I don't blame them since this is where the profits seem to be in the headphone market. Hopefully the AKG "by Tiesto" headphones don't sound too bad. I'm surprised Sennheiser has not jumped on board...

I haven't been able to find the HD-25-1 II for less than $240 in Canada. I'm having a hard time convincing myself they are worth that much. If I came across the adidas version going for $150 I would definitely jump on it. The U.S. prices are a lot more reasonable at $200 for standard HD-25-1 II.  

Most of the suggestions above (ie. DT-770, K550, srh-840) are too big for portable use.   I'm in a similar situation and currently looking for small portable headphones. Both the AiAiAi TMA-1 and Beyerdynamic DT-1350 appears to be comparable in terms of portability to the Sennheiser HD-25-1...

I am sure the list is endless for DAC's under 2k. It really comes down to the features and specific budget. Just to list a few high end units that compete in this price range:   - Anedio D2 - Violectric V800 - Grace 903 - Audiolab M-DAC - Benchmark DAC-1 (Already mentioned) -...

  Quote:   How long has it been since you sent them to Audeze? I am dreading if I ever have to send my Lcd 2's for repair.

I picked up this Weller WLC100 iron recently. Works fairly well compared to the no name iron I was using before. I regret not getting the Hako FX888 for only slightly more at the time.

I have both the M50 and DT770-250ohm. In terms of bass, the M50 has more bass quantity. The quality of the bass is much better on the DT770's. This is my experience anyways. I have also heard Beyerdynamic headphones may vary between production runs.

Quote: Tam is charging a nice premium for that op-amp. You can get the same op-amp from digi-key for $3. http://parts.digikey.com/1/parts/457905-ic-opamp-audio-ster-ab-8dip-lm4562na-nopb.html

The JDS labs preassembled O2 does not have the options the OP is looking for. The B3-080 case is required to fit 1/4 jack, RCA inputs, and relocation of gain/power buttons. Most likely custom front and rear plates are required as well.

Quote: +1 The Grant Fidelity showroom is just a short drive for me. It makes the warranty process a lot easier if I have issues with the equipment.
