Another Hafler

TrashyTrucker

Hey all,

Found and bought a amp off of fleabay. Its another Hafler (that makes two now) it is the 9505, still in the trans nova series. My other Hafler amp is the 9500, it (9500) only has unbalanced inputs only. The 9505 has both balanced and unbalanced inputs.

I unplugged the carver tfm 35, and now I am running both the haflers. I now have space heaters for this winter! LOL.
Anyway, the guy that sold me the 9505 enclosed a power cord that probabally belonged on a PC! I
knew that wouldnt work! So off to the stereo store I go. I ended up with these in 2 meter:

The stereo salesman gave me an idea and I wanted to bounce it off you guys heads. He stated I dont need much wattage to the highs on my 3.1TL's
and futhermore I could bywire off an AVR for the high inputs of the tweets. And then he suggested I bridge the Haflers and run them on the lows. That would bump the Haflers to 750w mono blocks essentially. Would this work? Would the highs be as bright?
When I upgrade to this:

The salesman said I could biwire the highs? The AVR is 135wpc x 7 stock I guess I need to read up on biwiring?
Anyways I just wanted to share the progress I have made on my system since I met you all. As always comments are always welcome.

regards,
Matt

I wouldn't recommend doing it.The first issue(among others) will be a possible gain mismatch between the AVR and the Haflers.If the gains are disimilar the frequency response of the speakers will become unbalanced.I should add that bridging the Haflers will make them non common ground thus incompatible with SDA's.

Thanks FTG,
I was not sure... I just wanted to get some input for now. I like the way everything sounds now anyway. But you know how it is? Something is always better, right? Would be nice to use the carver for the highs and use both haflers bridged for the lows! But I dont know how I would pull that off. :rolleyes: LOL;) Again I was just dreaming... I like how everything blends together now on my system.
Also:
I just auditioned a 50k system today and was totally blown away! ALL MCKINTOSH setup with the 801B&W's! 1200w mono blocks w/both your choice either a vacumn preamp, or solidstate preamp.

Hi Matt,I edited my post above but to reinterate,you cannot use bridged amplifiers with SDA's unless you have a special transformer isolation cable designated the A1 IIRC.
