I have not come across an owner's thread for Gemstone though i know quite a few people have used/ are still using it.


I am driving my Dali Helicon's through the Gemstone and can't believe how effortless and powerful this amp is. It's also sad that not a whole lot of people are aware of this amp which(IMHO) is a great value for money in light of what it offers.


I believe the Gemstone scored very high points in the amp shootout done a few years ago here at AVS as well.


Here is the link to their website that also has the specs listed.

It's probably the one piece of gear I have held on to the longest. Before I had the lpa-1, and the sherbourn 7/2100. This amp is great and a steal IMO.

I don't own the Gemstone anymore due to changing of speakers. When I did own it I had the Meridian 861 with 7 M&K S-5000's. I was running all balanced cables. With all of the amps I have owned(alot within 4 years) if someone is looking for a very clear, neutral and powerful amp for movies or music this is the one. I now have horns and I bet it would still sound great but I am trying out McIntosh for the slight warmth. Did I just call an amp warm.

Great to hear from fellow owners
I agree with you, this is one piece in my gear that i don't envision having to change for a very long time... I'm very impressed at how effortlessly it delivers. Even after the hardest of driving i have never noticed it even slightly warm to the touch.

thanks for replying! I'm sure that McIntosh gear would be very nice! Not to mention how attractive their amps always are.


I can totally relate to your statement of clear, neutral and powerful.. the Gemstone basically outputs what you give it and very cleanly. I have a Marantz AV8003 Pre-Pro that helps in the warmness area instead

I have been through acsends, paradigm reference, b&w nautilius, energy veritas, rockets, aerials, x-statiks, and not psb synchronys not to much various prepros and receivers. The gemstone has run them all effortlessly. There is something to say about the neutrality and control this amp has. Very refined.

Have any of you guys any comparisons to ICE powered amps such as something from W4S or D-Sonic?


I ask because I'm amp shopping. I always manage to sneak a look at the Gemstone and have it on my list. Its the only non D class amp on it.


I currently run an 7125 Outlaw and while I can't say anything bad about it per se, I want more power right now. Right now its probably down to a W4S 7x 250 or the Gemstone.

Sorry Wally, i myself do not have experience with either of those amps.. but i have read comments from lot of happy Gemstone owners who have been amazed by its performance.


I had a B&K earlier to compare with the Gemstone and the Gemstone while sonically is not too different, it brought a certain airiness and openness to the soundstage and felt really clean and effortless.


I know all these things are hard to quantify in real terms but that is the general feeling i get from it. I feel it takes the whole part of even thinking about an amp out of equation in your setup(which is a good thing)... kind of like being a very strong link that you never have to worry about.


If its power you want there is no way you would be disappointed with the Gemstone believe me.. its 200X7 at 8ohms and doubles down to 400 under 4 ohm loads. If you were closer i would have loved to give you a demo.. maybe you can find a dealer/owner in Chicago area. Wish you all the best in your quest and whatever amp you end up deciding on.


There is an old thread here somewhere about the amp shootout, ill try to find it and post a link for comparisons. I believe they compared the amp very favourably with other amps costing twice the money.

Hey thanks for the URL! I've been amp shopping for several months and I did see some of those posts from that shootout.


I appreciate your comments and thoughts about the amp as well. I am one that agrees with your comments about not knowing an amp is even part of the equation. To be honest, the Outlaw has done a good job in that respect - no complaints. I think the Gemstone will provide the power I'm looking for though. I'm looking for "coverage" power not sustained at the peak type. My speakers can go to 4 ohms and even to 2 under the right conditions - and I want the right amp; I don't want to be buying an amp every year.



I've read some wonderful stuff about the W4S amps ability to provide a wide soundstage and "depth" I guess would be an apt term. I like the low heat and light weight of the D class amps too. I believe either one would work well for me.


Thanks again for the help.

I hear you Wally! Amp is something i would also not want to upgrade in my setup for a long time(and currently i feel this will be case). The light weight of the D class amps seems attractive.. the gemstone is really heavy. Regarding the heat factor, i can comment from Gemstones perspective that i have never felt it even warm after the heaviest of driving so they may fare equally there. Let us know what you end up choosing!

My Von Schweikert VR-4JR are 2.4Ohms from 60-160Hz, and the Gemstone has no problems driving them at very high volumes. This amp is a keeper.

I have a gemstone that has been faithfully driving both my system, REF50S2, SF Cremona and Polk LSi's, since 2005. Very happy with it. Haven't been tempted to upgrade for a long time, thanks to Gemstone.

Nice! How do the Sonus Faber's sound with the Gemstone.. i had them shortlisted along with Dali when choosing my speakers a few years back.


Would love to see some photos of your setup if you have em.

Hey Steve,

How is everything? I am back to McIntosh again since I have horn speakers. They do match very well together. I remember trying out amps when I had the Gemstone and the Gemstone just had that extra clarity and smoothness compared to the others. I even tried pure class a monoblocks in 2 channel versus 2 channels of the gemstone and the gemstone was still slightly better. Surely a great amp. If I ever change speakers again that are more neutral(you no me) expect another call. I keep hearing good things about the new Emotiva amps and are tempting to try out. I am happy right now running 320 watts per channel of Mac into big cinema horn speakers. Talk about a cinematic experience. Check out my signature.

Welcome to the thread Steve and thanks for making such a fantastic amp
I don't think i will ever feel the urge of upgrading from this for a long time.


The only thing i wish a little different was if it was a little smaller in length as im finding it hard to find normal av racks(like Salamander) to fit it. But i'm being nitpicky here so please don't mind.



Did I mention again how much i love this mated with the Dalis

Those Dali's are VERY nice looking speakers. In the right speaker I love ribbon tweeters...I take those Dali's are the RIGHT speaker?

Hey Steve and fellow Gemstone owners, current and previous. Still have my Gemstone sitting nearby pumping out some good music while I type this. For the price, well actually quite a lot more, this is the best in regards to neutrality and clean power that I've had the pleasure of listening to over extended periods... not at shows with killer setups.

Daman;


Not to take this thread off course but I hope to add a pair of 2 ch speakers to my "stable" and those Dali's have just made my list.


Back on thread, I'm about this close to owning a Gemstone thanks to you guys and a pretty cool discussion with Steve. Once the frozen tundra weather releases it's grasp on the Upper Midwest, I'm going to jump on one of my motorbikes and go visit Steve in MN. Give me a chance to check out a real store too.
