Using the forums for financial gain, under the guise of "providing information", is both unethical and inappropriate. And it's the usual suspects time after time.
Audiogon provides a classified section for vendors to sell their products.
Georgelofi produces a passive preamp and he advocates going direct from DAC to amp bypassing PREAMP. Where's Georgelofi financial gain? In fact, he's offering his honest opinion and potentially hurting sales??
Rustler: Almarg and I have both told you have a great match to go direct, and adding an active pre is going to do nothing but colour the sound and put a hole in your pocket.
This is true only if the signal from DAC is PERFECT and NOT colored. If not, adding a preamp can improve or degrade the original colored signal.
Also spec (a great match) doesn't necessary equates to great sound. Otherwise all components with the same spec will sound the same and from my experience, it doesn't.
Rustler, there's no definitive answer so only way to know is experiment forself.
