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.

These two pairs of speakers are very different. sounds like you like the M3s better. It is a mistake to assume that the more epensivve speaker should sound better.

The Graham is indeed less sensitive but more power may not make it to your liking. I’d try to borrow or audition an amp before I spent $10000 hoping it would sound good. That is a way to send good money after bad.

Where are you located? I’d love to hear the spatial audio speakers in my system.

@mezzguy2 I recently heard the Graham LS5/5 at Philip O’Hanlon’s house a few weeks ago. We spent a number of hours with the speaker, and I was able to get acquainted with the sonic presentation of the speaker and the electronics. More recently, I was also sent a pair of LS5/9 to demo for others, and I took the opportunity to get to know the Graham brand more. 

Given my experience with both Graham and LTA, I would think they are not a good match. It’s not about the power rating, but simply just how the two are voiced together. The LTA is as linear as can be, with a light amount of tube harmonics. Grahams were designed from a foundation of being British studio monitors. The electronics of the day in the UK were a bit warmer, more harmonic, potentially less transparent. The Grahams on the other hand are very revealing, and quite dynamic that they will show any shortcoming of synergy through the chain. 

You will be better off pairing the LS5/5 first and foremost with an amplifier that delivers with richer harmonics and is more refined in presentation. High current will also will wake the speaker up (it doesn’t take that much, but helps to in tandem deliver the harmonics and the control and slam).

I do have a strong recommendation, but as a dealer, I’ll refrain from listing it out on the thread. If you want to discuss more, feel free to message me direct. Otherwise, I think I’ve otherwise given you some considerations on amplifier types to pair with the LS5/5. 

Happy New Year!

Lots of different pre/amp flavors out there.  What sound characteristics are most important to you, and what other improvements might you be looking for over the LTA besides power?
