feeling Tactful today

To be honest, I don't really know Reg, although I imagine that the backwave of the ELS is going to create some kind of phase cancellation unless the rear wall is heavily treated

 

Merlin

have you had experience of Silver Arrow cables used with TacT?
Guy at TacT was quite keen to tell me about them, but then he is selling them....

 

Could be. The existence of the backwave is the reason why ESLs need to be at least 3 feet from the front wall if you aren't going to attenuate the bass frequencies with phase cancellation. Maybe the RCS helps us Quad owners achieve a lift in our 'non-existent' bass

Do the RCS room plots of Quad ESLs look much different to those using dynamic speakers? And what are the main parameters which require correction - is it time or frequency domain in the systems you've seen?

I think phase cancellation in the bass happens regardless of how far from the wall the speakers are, it's to do with wavelength and speaker size.

Penance, good to hear you're having fun .
With regards to 'Aggressive Speaker Placement', I was referring to pushing them closer to the walls, in a configuration that was not possible with the Rotel. As AK mentioned, the increased control of the cones gives you license to move your speakers around as they don't excite the room as much.

With regards to the qualities of the S2150, Merlin pretty much hit it on the head: Very clean and clear; with no real signature at all. So it's shit in - shit out . A good pre and source are essential in my book.

 

Agreed Paul, and it isn't just confined to dipoles of course. having said that, the distance will have a bearing on the frequency of the cancellation won't it?

 

yes I do beleive he is trying to sell you some!

Apparently they are OK, but I have no exprience of them other than winding the designer up at Heathrow with the standard "Cables Shmables" ZG tactic. He seemed less than amused!

IME a silver cable is unlikely to warm up the sound.

 

Fits with my experience of silver cables.

 

Tis true, the ambient heating qualities of Silver (natural state), are somewhat scarse on this Planet

 

TBH I did think it was sales talk.

 

Penance - are you liking the amp yet?

If not, have you discussed a store credit where you bought it from?..

It would be a shame IMHO to keep something that doesnt tick all your boxes..

Cheers

With a dipole you can hear the front and back at the same time, unfortunately they are out of phase, hence the bass rolloff.

You're going to get all sorts of effects from reflections, regardless of speaker technology, but the bass cancellation of a dipole is a distinct phenomenon directly related to the minimum speaker dimension. Quad put a resistor/capacitor in the input circuitry of the speaker to help compensate. It's tempting to remove this ugly large non-polarised electrolytic and make a small active equaliser box to go between pre and power to do the same. Something like Kef used to do.

It wasn't from a store, came direct from TacT UK with a 3 week home trial. So at the end of 3 weeeks i can get a full refund.
I am liking it, but i was spoilt with the B/C, and to be honest, i think i prefer the B/C sound. But the TacT still needs run in time, so i'll not make any final decisions yet. Also a B/C will cost me more i suspect.

 

Thats good mate. You can really enjoy your audition period then, maybe even getting in a few competitors to see who comes out on top!

WM is the one to ask about second hand BC prices.. 1500 ish?

 

FWIW I really think you want a Bel Canto, and that you ought to return the TacT after your three week trial, save up for a little if necessary, and splash out on the B/C. The only way to be happy in the long run is to get what you really want in the first place, as I decided when looking to spend £350ish on an amp (ended up with the S300 :shame: ).

 

it's got to be a evo 4

Tone can you really get these for 1500 or were you thinking about the integrated. mrs johnh still hasn't found by bc which is wedged behind an armchair. I've a feeling the blue led is going to give it away one of these days

I wouldnt of wanted if i hadnt heard
Played around last night, quite enjoyable, but the girly and my mate both think the Rotel was nicer
I think i would probably go for a 200.2 with a view to bridging at a later date, assuming the TacT doesnt stay.

 

Sorry to hear that the tact isnt doing the biz for you. I suppose its still very good for the price though.

 

Yes, it is a good amp, I should stress that. Nothing realy wrong with it ( assuming the hard edge 'is' a run in matter), Just not my presentation.
Must admit, I wouldnt agree with the idea that the Rotel is better.

The 1500 priceing is for a 2 not a 4.

 

Just seen that bit. It would be an ideal situation, but my cash is held up in the TacT at the mo. So it would be a case of starting again after the trial.
Also Mrs P's b/day next week, i should use some money for that
