Jadis JA30 Mk2, how great???
Hi all, I am the new owner of the Jadis JA30 MKII. May I know about how long it needs to be burnt in to achieve its full potential? Newly fresh out from the box which was already pleased me so much for its precise & detail sound! I do believe it need to undergo a long journey before it becomes stable, isn't it? Allan |
Moreover how to compare a JA30 with its SE300B? If output driving power wasn't be a concern?! I have much interest to get a pair of it as well？How would you all thoughts about its performance? Though it wasn't a single 300B tube amp, it still caught my attention for a push pull single ended type of amp which just deliver a 10W only power. It should have plenty of driving power?! Is it? Thanks! Allan |
@samhvcc Congratulations on becoming a new JA30Mk2 owner. The amps do need a little run in before they can show their full potential, like all new gear. I would also suggest, like the manual states that you don’t listen that carefully until about 1.5 hours of playing time has gone by. The large transformers definitely do need some time to get ’warmed’ up. Nonetheless, the amps sound amazing from turn on...just a little better after the transformers get ’warmed’. Also, after you have lived with your amps for a while, I would highly recommend rolling in some NOS tubes into the 12Ax7 and 12Au7 positions. I just rolled in some NOS Telefunken 12Au7 smooth plates and some NOS Siemens 12AX7’s - this makes for a big upswing in SQ. As to your question about a 300B amp, I am not understanding your point. The Jadis can deliver up to 45watts/ch...where does 10watt/ch come from? |
The SE300B is a different Jadis amp actually and it looks to be parallel single ended and not pushpull hence the lower wattage. http://www.jadis-electronics.com/en/se300b-43.php |
Got it. I'm not really a fan of 300B single ended amps. Not because I don't think they sound good, but more because they are so very limiting as to the speakers that you can match them to. Plus, I think in many cases the 300B tube is more susceptible to noise from microphonics. In that perspective, I much prefer an 845 ( which Jadis also makes). |
