Alternative upgrade path - what next for WA6Dear all,
Having read all about the VCaps and Blackgates I was tempted to send my beloved WA6 to Jack for the maxxed out internal revamp. It would cost me over US$500 but I think it was worth, given all that I have spent on the WA6 and the tube compliments..... until
Jack told me that in my case it is better to upgrade to a WA4, which will be a definite one no regret step above the WA6. Jack said the WA4 will improve on impact and speed - something more difficult for a tubed amp than a solid state. He went on to explain the WA4 is available in headphone amp only version, and will deliver a performance very close to the WA5. I then have a look at the WA4 specification - indeed it is a class above the WA6. Although both use output transformer coupled topology, the WA4 is luxurious in audio terms : independent power supply for each channel, inductor for each channel, separate high and low voltage supply, dedicated rectifier per channel, and a full assortment of inputs (up to 4) plus loop out. Better still, upgrades like VCaps, Blackgates will also benefit the WA4....
Now I am at the cross-road, and don't know what to do. Yes, there is a huge cost gap between the maxxed out WA6 and a maxxed out WA4 option, but the additional features ( like a much lower THD in WA4) is really tempting. Plus, the use of 12AU7, 6922 will make good use of my tube inventories.
On the other hand, the WA4 does not look pretty - 6 blocks of transformers and inductors have created a over-crowded amp. The tubes are cornered in a small place and does not appeal cosmetically....
So I would like to hear what you guys think. Apparently now many have heard a WA4 but still I would welcome thoughts on which way to go.
Many thanks in advance.
