Then the 332 is close to the 337? so how close is the 332 to the doge? lol.
The 332 is very close to the 337. However I don't necessarily think it's fair to compare the Doge to these amps.

I think people have their greater than/less than signs confused. The 337 is the best, the 332 below that, and the 336i below that, in terms of sound quality. The 336i is a nice amp, but it's nowhere near as good sounding as the 337.

> = greater than
< = less than

At least that's the way it has been in any math class or electronics course I've ever taken. However, when I used that symbol (>) in my post above, I was referring to hierarchy (path, ascending), not specific values.

Now I wish I had gotten the 332, damn...

I dont get it. Why is it not fair to compare it? Cause its a different setup thingy? lol. I'm like struggling to make up my mind between the 332 and the doge now...

Because I think their sound signatures are very different.

Get the Darkvoice. I think the build quality is better. It also looks like a tube amp. The Doge looks like a lunchbox.

The replacement tubes are cheaper. The Doge uses a 12AX7 and two EL84s. Those tube prices are some of the highest out there. 332 tubes cost pennies.

The 332 is almost a dual-mono setup, in that the left and right amplification channels are separated. Only the power supply is shared. The Doge preamp section uses only a single 12AX7.

I think the Darkvoices are also more popular and as a result you'll have wider community support.

Good point. Also, I give a guy credit for thinking not only of himself, but others...

well, with head-fi having been down I was "forced" to listen more to my DV 337. :-)

I have been going back and forth between 6080 and 6as7 tubes.

I don't think I have JAN 6as7's, they are commercial RCA, so if anyone knows a good source let me know.

The 337 continues to impress me and level matching hasn't been the PITA I was anticipating.

the only downside to this amp is that it sounds so good it is taking me away from practicing, it's kind of hard to listen and practice guitar at the same time.

Vacuum Tubes, Electron Tubes, Tubes, Tube Testers and Electronic Parts has the RAC CRC JAN 6AS7's for $20 + $9 shipping, last time I emailed him last week. Till I get mine I am using a black plate RCA 6AS7

Sure is! Hi Larry, Hi Tom.

I do find the JAN-CRC RCA 6AS7s to sound better than the standard versions.

With the 337, a pair of good 6SJ7WGTs is also very important. I have been trying a few different ones, as well as some of the loctal 7C7 versions. This is a bit of a time consuming process since true NOS 6SJ7's are horribly buzzy for quite a while before the become silent. I will report that back soon.

I bought a used SinglePower Extreme, and I have compared that to the Darkvoice 337. The Darkvoice is the better amp IMO.

Good to hear the JAN's sound better.

The commercial ones seemed a bit less tight in the bass , had less detail and less dynamics than my 6080's, at least in my initial impressions.

I really have to do some more comparisons, though, because I could easily change my mind, so please don't quote me :-)

Also good to hear you like the DV better than the SinglePower, now I don't have to spend more money.

BTW, if you do find a better amp than the DV will you please just lie and say the DV rules?
My wallet hurts enough as it is :-)

I thought the tubes used were 6sj7, not 6sa7?

And to clarify, the 6528s are equivalent to 6336a?

Thanks!

The DV 337 uses 6SJ7 driver tubes, and 6AS7 power tubes.

I am not sure if the DV will accommodate some of the "alternatives" to the 6AS7. Only the 6080 is truly identical. The 5998, 2399, 421a, 6528, 6336, 7208, and 7236, are all electrically different enough from the 6AS7/6080 that they might cause problems.

I will say that the 5998's sound better than the 6AS7's in my SinglePower extreme, so I would love to try these in the DV337, but I am afraid to. Has anyone tried them?

Does anyone speak chinese that could post a tube inquiry on the DV forum
about the 5998?

Maybe Jasmine would do that for us?

As good as Jasmine's service has been for me, and it's been top-notch, Jasmine has never answered any of my tube-rolling questions...
