Default Best amp with 2sk1058

Hı. I am looking fr Th best amp around 40w rms or over made with 2sk1058 and 2sj162.It is because I like the sound f 2sk1058 lateral mosfet. I think it has a Magic. I bought a kit but my friend told me that it is clone f Goldmund and needs one more driver stage
Here is the kit
M1 mos FET Stereo 70W 70W 2SK1058 J62 Kit WLX 8 | eBay
Do you know a better circuit ?What is the best i can build.It can be class aab. I am not looking for a class a amp. Thanks and best regards

Check out Cubie 3. I have built Cubie 2, and juma reports Cubie 3 retains sonic attributes with higher power. Cubie 2 is among the very best amps I have had the pleasure to hear.

Hı Moly.I am sure it sounds very good.Why have not you used low noise transistors like bc560c and bc550c ? Or Japanese equalivents? Can circuit be upgraded this way ? Thank you and best regards

No real reason, the devices used were to hand. The 2SA872A (obsolete now) would probably be one device that I might have considered, but I think you will find (in practice) that any semiconductor changes have a very minimal impact on noise performance for this design... mainly because the other component values and general topology are the dominant factors.

Used with fairly sensitive B&W703's, noise is only apparent with your ear a cm or so on axis from the tweeter.
