Egglestonworks Andra II: How difficult a load?

I think you might have enough power if you run the amps in A/B mode, as your amp has 100 wpc that way, right?
In pure Class A mode, you only have 70 wpc, which I think would not quite be enough to get the full bass response you can obtain from these speakers.

I am using Lamm M2.1 monoblocks, which have 200 wpc. I have plenty of power, and the bass response is incredible. (In fact, I think there is slightly too much bass for my room, and I am getting ready to start installing room treatments to tame the slight mid-bass hump I seem to have. My room is 24' x 16' x 8', which unfortunately means lots of room nodes.)

I think having 100 wpc would be barely enough given the size of your room, which is slightly larger than my own. However, I think 200 wpc would be better, IMHO anyway.
(However, if you really want these speakers, you can always give them a shot with your current amp, and if it doesn't work out, you can always upgrade the amp at a later date. Been there, done that!)

I have recently upgraded to these speakers a few months ago. I like them a lot so far, and they have the potential to be my last pair of speakers. I will state that these speakers require a lot of work to get them to sound their best though, as they are much more difficult than any speaker I've ever had to set up before - well, at least in my room! I have tweaked their position, and toe-in, several times, until I have them where they sound very good. And, I think I might be able to tweak them some more to get slightly better sound, but I am having too much fun listening to them now to bother! (They are much more finicky than my Revel Studios were, or even my Martin Logan Sequel IIs, in terms of ease of setting them up.)

FYI: Take my last statement as a "heads-up" word of advice, as I am not trying to put you off getting these speakers, as I think they have the potential of being as close to the Rockport Antares (my favorite, but out of my financial reach, speaker!), as I can afford. They have a great tweeter, with lots of HF extension, the mid-range is fantastic, and the bass response is very deep, quick and powerful. (They image and soundstage nicely too, and the speakers seem to disappear about as good as any speaker I've ever heard.) And yes, these speakers can play LOUD! (I too like rock, as well as Jazz and pop.)

My two cents worth.

PS Feel free to contact me with any other questions you might have.

I use to own these speakers and they are marvelous, I originally had them paired up with McIntosh 501 mono blocks with great results. I then got some Pass X600.5 mono's and prefered this combo, I also tried CAT JL2 Sig. stereo amp and this sounded great also. I never got around to trying the Lamm's but they were on my list also to do. You can't go wrong with these speakers and they will work very nicely in the room size you have mentioned so just build around them. If your amps work out that will be a bonus, should be no issues at moderate volumes but more demanding I see your amps running out of steam.

Regarding set-up in my place, these were one of the easiest I have ever owned. Prior to these I owned W/P7's and then Revel Salon's.

Put them onto Sistrum Platforms and everything with be improved.

It is very difficult to give any opinion in these principally individual and perception based hobby. What is dynamic for one, could be sleepy and boring for other. A friend of mine has the Egglestonworks Andra II. He was really struggling to kick out dynamism and attack from these monsters. These are very difficult speakers. He had first Antique Soundlab 600 watt tube monoblocks, recommended by Salvatore, for difficult speakers. He had a nice flowing musical soundprint, but with somewhat pompous, slow bass. Whenever he came over to hear my old and outdated active speakers, he went home saying that his system is just not up to the task to deliver dynamism and attack. He changed his power amps to Spectorn Musical IIISe. Still, he felt that the Andras still were sluggish and boring. Finally, adding an another Spectron and converting them into monoblocks and thus pumping whopping 1800 watts he finally arrived to the same level of dynamism what an old active speakers could deliver. Rest of his gears are a nice vinyl rig and EMM Labs digital rig. I hope this helps.

Ajahu, I never had the problem you were describing in your post. It most defently is not a speaker issue, I would look else where within the set-up, or possibly it could be a room issue. Now I'm not saying that they are not a easy speaker to wake up to get the best out of them. What has me puzzled is that you mention after inserting another Spectron amp "1800 watts" he finally arrived to same level as your old active speakers. What active speakers are you speaking of. I was over at a person's home who had Cardas speaker cables hooked-up and the sound was boring, sluggish but after just making this one change the system did a 360.

Dev, this is a very subjective hobby. But, the most critical link, according to my opinion, is to find the right amplification for a given speakers. That is where the crucial synergy necessary. If one does not have the right synergy, no source or cabling or any other typical high-end sound treating tricks helps. My goal was to support Kurt-tank opinion, and warn Robal that he may need to invest heavily into amplification, especially if he likes blues/pop and not lush and romantic sound of violin sonatas. Actually, your example is also underlines this opinion. I am sure that with 600 watt monoblocks you also don"t not have any problem to drive these speakers. But may be there are some differences between a 100 watt tube amplification and 600 watt solid state monsters.
