great review thanks

A few questions for you HeadphoneAddict, if you have a moment: 1) I'm curious about the Raytheon 6AK5 replacement tubes you used. Are they military grade tubes? I've been looking at tubes on eBay (sold by one of the popular sellers that tests and matches), and I found that the military grade versions cost nearly twice as much. On the EF2, is it worth going for the military grade (or otherwise high-end version such as Sylvania Gold etc)? 2) I read your review for the Travagans Red/Green/White, and I'm curious if you have an impression of the White DAC performance vs the EF2 DAC since they use the same BurrBrown 2702. Since you no longer have the White, and you can't exactly evaluate the EF2's DAC directly, I know this may be a tough question. But do you have an impression of how these two units compare to each other? I was originally thinking of getting the White for a simple office DAC/amp unit. However, now I'm thinking of getting the EF2 and using some of the money I save to buy a pair of upgrade tubes. |

Can't read them while they are in the amp, and they came two to a single box with no print. I think I paid $25 for the tubes. 2) I would say that the White's DAC is on par with the EF2 DAC. It is a bigger guess on my part to say that maybe the White with a pair of OPA627 opamps on a 2:1 "over/under" adapter would sound somewhat similar. (about $340 for both amp and opamps after shipping). |
