I have no problem with switch thump. But have gone back to my 41hz amp 6 basic blinds it in every way sounds more real natural and dynamic. Any one who as the t1 board get your self and amp 6 basic and you will hear how poor sounding the t1 board is

I recently compared the T1 to the T1 with mundorf input caps, and the difference is quite big. So I'd recommend again to try some other input caps on the T1.

I think your T1 may be faulty too if it sounds as bad as you suggest

My new board sounds excellent, smooth and detailed top end and solid extended bass, no harshness whatsoever.

I agree - ask to try another board - you should be getting a just noticeable increase in quality and 'magic' as well as a few more watts with this comparison... I sometimes think my T1 is a bit too mellow but in general its great.. :-)

Im not saying anyone is wrong but have you heard the amp 6 basic. Compared to the t1 board. I admit the t1 board sounds louder but not as dynamic if that makes sence. The 41hz amp comes nise and smooth then when there is a loud part in the music it does come louder. But not just that female vocals sound natural with no harshness diana krill girl in the other room sounds great with the 41hz amp but the t1 just no were near as good

Hi
I have built several 41hz kits including the amp6 and i have purchased the T1 among others - rest assured there is something wrong with your particular board or set-up if it is sounding worse than the amp6. As stated before you should get a noticeable improvement in quality and 'sense of more unlimited power' (from the additional watts) here. Amp6 is a very good amp but is based around a chip designed for a car radio... the T1 uses technology that is 'more spread out' and can sound absolutely amazing with the right configuration. Ask for a new board to be sent..

If you are sure you have eliminated all potential set-up problems I suggest you just contact them and ask.

Things that could produce harsh, bass lean sound are
  • poor ground connection on signal in - causes both channels to carry difference between left and right - poor bass and distant voices and mad wide sound stage give this away - check your wiring and that all the plugs/sockets are ok.
  • Poor impedance matching on input - i.e. its overloading your source signal - causes a boxy, restrained harsh sound - although input impedance value should be similar to amp6 but the pot might lower this a notch?? (check it is 50K as suggested) - and/or try both amps with a low impedance source such as headphone out from MP3 etc.. If that is better then maybe you will need a preamp/buffer for you source..

Hope this helps..

With any luck you'll only have to return your amp to Norway for a modest postage charge. That's what happened when I asked for my amp to be replaced after e-mailing mail@hifimediy.com.

The new amp came quite quickly from a UK address. All in all I'm very satisfied with the service I received

I'm thinking that you have dicked around with the ancient Marantz to the point that the things' output is seriously reduced... problematically so.
The Amp 6 "should' power your speakers Quite Adequately.
Try an Unmodded CD player or MP3 or whatever you can borrow as a test of this theory.
