Magnepan LRS+ resistors on the tweeters… which?

How long have you had the speakers? Is it possible that they are not fully broken in?

@yyzsantabarbara those two amps must be great with the LRS+. In a natural and logic way I am trying to work with the 5 amps that I have available before any thoughts on anything else. The Coda and Sanders are not only very interesting but also expensive and unavailable in Europe.

I bought the LRS+ sure that the Vincent SV-237MK (that drives everything) would pair well with them… and it is ok but there is that treble level issue. 

My second choice was the Rogue Sphinx, referred by some as a good match… but there was that treble again, irritating high.

It was not about treble quality (I saw that could obviously improve with burn-in) but it was the high level, something that I perceived to be within the speakers character.

At that point (with more or less 100 hours) I could:

1 - try the resistors, although not the stock ones, spending 50 euros.

2 - buy another amp, spending at least 750 euros on a used power amp.

The first choice was an easy one :)

Now, after about 250 hours, with the 1,5 Ohm Mundorf resistors that did reduced effectively the treble level and didn’t affect the sound quality, is natural that my questions are about the resistors, to learn from other’s experiences and to see if I can get even better results.

@gbmcleod my LRS+ have about 250 hours on them.
Regarding the treble high level, in my experience, like I have mentioned in the previous post, that kind of thing is more a characteristic of the design and not something that can be fix with break in. The quality yes, the high level I don’t think so.

Of course, there are some (many?) users that don’t share my experience about the speaker’s balance / treble high level. Perhaps they are less sensitive, perhaps they already had a suitable high current/ power amp, perhaps a bigger room, etc. 

But what is clear to me is that if that tuning of the treble is included in the design, then it must be a real thing, addressed in the design process.

@toddalin I thought that we must stick to 10W resistors!
Anyway, I can’t find the Mills in Europe and I am not willing to pay $60+ on shipping and customs alone if I buy abroad. Here I have available the mentioned Mundorf, Duelund, Path Audio, Ohmite, Jantzen, Amtrans… but still is difficult to get a 10W 1 to 2 Ohm resistor in most brands, usually not in stock.

@yyzsantabarbara  Thanks! I cancelled my order for the Risers after discovering that I had much better integration with my subwoofer with the LRS+ on the floor. I tried to buy the jumpers after cancelling, but he wouldn't sell.

@yyzsantabarbara ​@audiofilo123  Again, I am really surprised that you both find the LRS+ to be hot in the treble. I haven't tried other amps with them but my AGD amp with my Backert line stage (PSVANE Horizon 12au7 AT) is absolutely sublime. Detailed, yes! Hard treble? Not at all. And like many of you I am very sensitive to too much energy in the upper mid on up. The only thing I have done to the LRS+ is replace the fuse with a ceramic fuse, and tilt them forward by about an inch.
