I haven't really A/B controlling volume from the DAC out of the nfb28 vs from the WA22. From experience tho I don't find much difference.

Thanks. I will give it a real test once the WA22 arrives.

The reason I would like to buy a max one is that I can also improving my hd800 at the same time..

Also, can the speaker out of the wa5 drive high efficient speakers nicely, if I put the speakers on my bedroom desk in a ultra small area(3"X3")?

Thank you for the clarification :smile:

I think the WA5 drives high efficiency speakers loud enough to fill up an even larger room. I have been able to fill the office space of 150 sq ft I have with a pair of Tannoy Autograph Minis (88dB) with ease, but bass was weak perhaps as it is the nature of the Tannoys and my shi*ty stock tubes.The recommended speaker efficiency is 90 dB +

For the price you may want to consider Eddie Current products such as 4-45 and 2A3 MKIV as well. But WA5 is much more commercially available in HK.

The most expensive part re WA5 is the tubes.

In general, you want to to push any volume control as far down the chain as possible, for best SQ. Typically, you want your DAC outputting standard maximum line-level voltage to your (pre-)amp (that is, 2V unbalanced or 4V balanced). If you attenuate the volume on your DAC, you need to then increase the gain on your amp, which increases the noise floor and reduces headroom. However, a little bit of attenuation in the DAC to fine-tune how you want the volume control to behave on your amp should be fine. For example, the WA22 and 6SE have a low noise floor and massive output power, so you have a good deal of room to play with.

Unboxing, etc. (Yes, I know the family photo of the stock and upgrade tubes only shows 13 instead of 16... as I mentioned some of the upgrade tubes and adapters were missing in the initial shipment, but have now been shipped.)

Photos of the amps in their final locations. Dubstep Girl is probably having a heart attack right now, noticing that somebody is still using the stock Shuguang 274Bs on Woos (the one in the 6LE actually rings like a telephone, it may not be entirely healthy), but the overall SQ is still killer. Upgrade tubes will be in within a week.

Sir, that black Woo amp is one of the coolest looking pieces of audio kit I've ever seen. Congratulations and happy listening.

:dt880smile: Easy DG...we all start somewhere.

post #30793 of 39044

I am making a shopping list of several tubes to try after I play with the stock tubes and then the upgraded Woo tubes for a while. This is gonna be fun!

Thanks for the great explanation.

You are making me drool. I can't wait for my WA22. Stock or rolled. I don't care at this stage.

Yes the AV32B-SL. A picture is worth more than a thousand words:

 

I've been looking for a NOS pair of these for a while and I've just tracked down a pair and purchased them :D  I'm using a WA5-LE (maxed), it will be very interesting to hear them.  The data sheet you posted states their operating life at 40,000 hours!!!  Did you find the sound quality changed much with burn in?

 

Cheers - Peter
