Hey Summer,
Enthusia's right and I'm confused.
To answer the rest of your post, yes, you can put a "dual" Opamp in the DAC socket, as long as it is "unity gain stable". If you want to try the LT1364 in the DAC, it is recommended you put a heat sink on it, because it gets hot without one.
As you found, there are many combo's to try and you may find one that suites you just fine.
The majority however, end up with the OPA627's in the DAC and LT1364's in the headphone amp after months of Opamp rolling. This is why Lawrence developed the "HeadFi Deal", so you folks would get a price break and not have to look all over the place for Opamps and spend months rolling them.

After checking your review on the op-amp combo selection, it seems like I can also swap the stock op-amp to a single LT1364 in the DAC section & 2x LT1469 in the headphone amp section, am I right? Is there a guide line or something to take note of regarding about swapping the op-amps on both in the DAC section & in the headphone amp section (other than to take note of single or dual channel in the op-amp)? In other words LT1364 in the DAC section & LT1469 in the headphone amp section & vice versa. Thanks! |
