I started out a few months ago thinking that I'd buy a relatively inexpensive headphone amp, I had in mind a budget of about US$500. After looking around I came across the WA7, so I upped the budget a little. Then I found out that the WA7 had a tube power supply (WA7tp), so up went the budget a little more. Then I discovered that there was the WA7d + WA7tp, so up it went again!
At this point I'd ordered and paid for the WA7d + WA7tp, since they were on back order I carried on reading and browsing. Then I discovered the WA5-LE!! So after much angst and shuffling of funds I switched my order to a WA5-LE + upgrade parts and Teflon sockets!! Just about 11 times my original budget.
I can't afford the tube upgrades at this point in time (I still have headphones to buy), but can anyone recommend any other upgrades to the WA5-LE that might improve its sonic performance as opposed to aesthetics. I'm in New Zealand and the shipping costs for returning the WA5-LE to Woo Audio for any additional mods would be prohibitive (US$500 round trip). So if there's anything else that's not too expensive and can be done before I take delivery, I might just consider it.
If you have any suggestions, please suggest away! I asked the same question of Jack Woo but never had a response.
