Seeking New Amplification for My Graham LS5/5 Speakers


Hello everyone. Looking for a little advice. I have a great pair of Graham ls5/5 speakers that are being driven by an LTA z40+ amp. I also have a pair of Spatial Audio M3 Sapphires that have been living in my basement. Having some free time during the holiday week, I brought the M3’s upstairs and hooked them up to the LTA and they sounded fantastic. Much better than the ls5’s, despite ls5s costing 5x as much. I think the LTA just doesn’t have enough power to really make the ls5s sing. Looking for some suggestions to drive them. I’m good with separates or an intergrated amp and buying either new or used. Think I need at least 100wpc. Also willing to trade the LTA. I primarily listen to digital sources (running a Grimm MU1 through and upgraded Mojo Audio Mystique SE-X). Budget is $10k, give or take. Thanks in advance for your help.

I have never heard the Spatial Audio speakers, but man do I love my LS5/5. I am using a Mark Levinson 585 with them.

Clayton showed the Spatial's with LTA amplification so the better match makes perfect sense but as blisshifi pointed out the Graham is an entirely different speaker with a different voicing and different current demands.  First decide which speaker you prefer and find the amp that fits it the best. You are not likely to find an amp that is perfect for both though there are several SS integrated amps that might be close.

@mezzguy2 I don’t have a recommendation as such, but I guess any British amplifier with a bit of grunt should be a suitable option.

I have the Graham Audio ls5/9 myself but am driving them with a Belles class A power amp, it sounds very nice, but the Belles only measures to fifty watts or there about, so better suitable for a smaller room.

The BBC designs are renowned for the tone and timbre and the true sound of un amplified instruments, am a bit surprised that you find the 5/5 being so bad sounding in relation to the Sapphire, it can off course be the room not suiting the 5/5 or maybe you are leaning more to the Sapphire sound signature? No shame in that, we all hear differently and enjoy different sonic, so maybe for you the Sapphire simply are the better speakers.

@ken6217 Interesting that the 585 is a good match, a beautiful amp that is indeed.

@gryphongryph It was the amp I had when I bought the speakers. I'd say it is on the neutral side, however my cables are warm, my DAC is an R2R NOS, and cables are on the warm side, and so I find everything works well together. 

When I went to listen to the speakers at the dealer, it was connected to a D'agastino Progression amp that sounded absolutely amazing. However it was more than I was looking to spend.

I actually had never heard of Graham prior to being in that shop. I had wanted to hear the Harbeth 40.3 XD but no shop that I called had any to listen to. After hearing the LS5/5, I bought them without even listening to anything else. They make music sound so natural.

 

 

Why would you want to spend $10K? Get a pair of Fosi V3 Monos with two 48 volt power supplies. About $400 and over 200wpc.
