For all you Super-T users, have you noticed significant increase in bass quantity over original T-amp, which some reviewers mentioned?

Also, has anyone compared the stock wallwart to a decent SLA battery on Super-T?

Have anyone use the MG OTL 32 DT to drive the K1K? from what I understand it was build with the K1000 in mind. any comments on it? I'm thinking about getting it.

The Chazz with KT-88's :

maybe not what some would consider a budget amp but 9W Ultrlinear with 5W Triode Strapped with the flip of a switch means it will drive everything from normal cans to the hardest to drive headphones and have the added bonus of being a tidy little speaker amp also.

Beam power and Vintage PRO AKG or AKG K1000 looks to be made for each other

I have it and I enjoy it a lot.
It does a decent job, but it's not the best I've heard.

Back to affordable decent amps: For $400, it's hard to beat the nOrh SE-9 for tubed amplification of the K-1000 (and I, for one, believe it needs tubes).

Is the nOrh SE-9 better then the MG OTL 32 DT? Can you expand a little on how the K1K sounds with the MG OTL 32 DT and the nOrh SE-9?

Thanks

Add max'ed PPAv2 to your considerations. If you plan on making your K1000s portable or transportable, not too many setups can beat a K1000 thru Max'ed PPAv2 with DAC

A steal at $800ish or more imho

On a scale of 1 (worst) to 10 (best)...

Antique Sound Labs OTL32 - (6) "OK", but not so great. I always thought something was lacking when I owned one, even with NOS tubes. A recent re-listen to a (more expensive) modded version gave same impression. Definitely needs the upgraded tubes (which ups the total cost). It's better with standard headphones, imo.

Chazz KT88 - (3*) Six Moons rated the Chazz far below the OTL32 in their reviews. Just didn't have the juice, despite the specs, even with the KT88's. *I haven't heard this amp personally.

nOrh se9 - (7.5) Pretty nice, especially after tubes are upgraded (added cost). Still not completely satisfying, nor bringing out all the K1000's are capable of, but decent.

Dared 300b monoblocks - (9) Despite their initial low entry price (w/o tubes), unfortunately these cannot be considered "budget" when the cost of the requisite tubes are added in. Built-in attenuators make a preamp not necessary (saves on total). Plug in a pair of WE 300b tubes and enjoy the sound.

SAC K1000 amp - (?) Dunno, never heard it.

Just my take on these oft-mentioned contenders.

A better source will go a long way toward a more satisfying experience with the K1000's. That's where I'd put my money first, even if your amp is a T-amp (or any current, low-priced digital amp/receiver). After that, I think a quality solid-state power amp that is on the warm side, paired with a tube pre is a good way to go with the AKG's.

Any thoughts on the SAC amp?

With stock tubes the norh SE-9 was a bit too thick for my tastes. The tonal balance was nice though.

Thick, as in Omega II thick? What about the treble?

That is a bit of a surprise since the KT-88 is anything but reticent and my own DIY SE KT-88 amp drives anything out there (built it for 600 ohm AKG studio cans ) including speakers so my assumtion was the Chazz would be a good match.Thing is I also have not heard the combination of Chazz/K1000 and was going more on experience with the KT-88 tube in aTriode-Strapped SE mode and not the actual amp (dumb,i should know better ).
Gotta read that review and maybe get a fell for why they thought this amp was lacking in power delivery but my suspician is that it is output transformer related and not output tube or topology related.

Chazz amp

At least one member here owned one with the KKT88's, and gave a fairly detailed review. Overall positive for most standard headphones but, again, not the best for the K1000, iirc.

Thick as in the classic tubey sound. Wooly bass. The treble was OK, better than the bass.

They May Be Power Hungry

FYI…

Here’s a response to my recent inquiry of AKG in a similar regard:

"The K1000's are designed to connect to your amp’s speaker lugs and require a minimum of 30 W/channel. 100 W is no problem but it is advised to lower the volume setting before powering up your system so that there is no sudden surge.

Also, if your amp is tube driven, be careful about leaving the speaker connection unterminated. The headphones have a break away point in the cable that allows you to store them without need to disconnect the cable at the speaker lugs. But, a tube driven amp may be damaged if powered on with no load. To protect such an amp you must put 8 ohm resistors of sufficient power rating across the terminals (one end connected to the positive pin and the other to the negative pin) so that even without the headphones plugged in there will be a load present."

In addition… here are related reviews on 6moons which address the ASL 32, ASL 15DT, nOrh SE9, and others - if you haven’t seen them:

And some more:

It sounds like the K1000’s need lots of power (minimum of 30 watts per channel – AKG) to drive them properly…

There is a definite increase in bass quantity over the original T-amp. The Super T-amp is not bass shy.

As far as the SLA battery goes, I'd really like to try that, but I'm kind of a noob and have no idea what kind of battery to buy or how I'd go about hooking up an SLA battery to the back of the Super-T amp.

I have an SLA battery for my Squeezebox 3 that I think I could use to power the Super-T, but it has a different connector and I'm not sure I could put it back together if I took it apart.

Any suggestions on SLA batteries and the Super-T?

Thanks.
