SKA GB150D now public domain...

Thank you still4given, and others for your replies.
Perhaps I can trouble you for one more explaination? If you say the GB150 is not as detailed as other amps, bearing in mind that the word means different things to different people, please can you describe from your point of view where the shortcoming in detail shows up. Is it space around instruments? Is it microvibrations and fine details at low levels like decay of notes etc? Many thanks!!!
 
I have an A/B setup. In most cases, once the two amps under test are equalized, there is almost no audible difference. However. with the SKA GB150 it was instantly apparent that the detail in the upper mids and highs is more subdued. I know the amp has a lot of fans, especially those who spent their hard earned money on one of Greg's kits. I won't call the it dull sounding, just subdued. If it were the only amp I had I would be fine with it. It is plenty musical.

Blessings, Terry

May be you should read this.

Hi Terry, thank you, your comments have been very helpful. I think I will interpret your comments to mean what I understand to be "the mosfet sound"
I think this amp is probably not for me.
 
Is that your subtle way of suggesting I go away for a long time and read 1500 pages 😉

😀
I can not explain it (simple way).
English is not my first language and I am not an expert here.

I simulated this amplifier, THD at 20kHz is 0.021325% (214W/4Ohm) and slew rate is around 30V/uS. The specifications are just adequate for me.

I like amp with high slew rate 😎
If an amp can not have low THD, make it harmonic profile like tube amp. Although it is not accurate but it is easy listening.
 
Hi Terry,

How would you compare your Honey Badger to the SKA, and VSSA ? I the type of build affects things a lot, I found my HB to be more clinical, not as warm as my SKA, I guess that I lean towards warmer amps. As for detail I find them to be the same, but prefer the SKA mids. Too bad the Aleph J can't put out 150 wpc it is the cleanist, most transparent, detailed amp in my collection but can't drive my 3ways as effectively as the SKA. With a pair of back loaded horns it's fantastic though, hard to beat. The reason I ask is that I'm looking for another amp project.

HI PJN.

I'm not sure how to answer that. I don't know what someone means when they say warm. to me that means there is an emphasis on the lower mids and a tempered high end. I would say that "kind of" describes the SKA. If that is what you are after I don't know what else to suggest. The next closest amp I have to that is the FetZilla. Very similar to the SKA. The next closest would be the ESP 101. It has somewhat tempered highs but not as much as the SKA. the FetZilla is not going to help you because it is less powerful that the SKA. You might want to consider the P101. It is 200W/8ohm and nearly doubles into 4 ohm. I think the Badger is beautiful. Big soundstage, clear highs, kickin' low end. When someone says "clinical" to me is either says the amp produces a true sound or there is something missing. I think the Badger is true to the source. I say the because 90% of the amps I've built and tested sound just like it. To me that is the job of the amp. Any "tempering" you want should be done by your choice of speakers. YMMV
