I have my 1st set of Magnepans (LRS) on order. I've read here and there about room size, but I don't know what makes small, medium or large.Mine's 12x20. The ceiling is 12ft. Is this a small, medium or large room? Would you recommend a sub along with the LRS in this space?By the way, I'll be using Emotiva Stealth PA-1 monoblocks fed from my HT receiver. I'd appreciate any thoughts on this combo.BTW, I've been following this thread pretty much since it started. Is there a way to be notified when there are new posts?Thanks!
Yep, had that NuForce in system for about 2 weeks. Sent it back within the 30 day audition period. (AudioAdvisor) Maybe with the "right" speaker, but it simply wasn't as good as the Classdaudio SDS 254 I had at that time. This driving the 4 ohm Spatial M2 Turbo I've mentioned in this thread. Apparently it doesn't like 4 ohm loads. I don't believe a 4 ohm power rating is ever mentioned in the NuForce specs either.
I have Magnepan 1.7i as one of my reference speaker pairs. I had MMGs for years and upgraded.Question is: How does LRS compare to MMG or even 1.7i? Regarding amplification, are these still "hard to drive" at medium-high volume? Can they handle rock music?One of my amplifier torture tests is to play the song Zombie at nearly max volume. The 1.7i was such a step up in performance, especially in the bass -- no sub needed for most listeners with DC coupled amps and direct drive from a DC coupled DAC. I wonder if getting a pair of LRS would be a good move since they are such an outstanding value.I'd like to hear from people who actually own a pair (or more)....
Yeah, I knew it was going to be apples and oranges here. I had the NuForce driving my 97db ZU Audio Omens. And it sounded spectacular with those. It didn't break a sweat. With the Maggie's, completely different story. PS Audio offers a $450 discount on the Stellar S 300 with trades so I am going to trade the NuForce in and get the Stellar S300. Seems like a spectacular amp. Or like you,go with a Class D Audio amp, I might get their top of the line SDS 470CS. 600 watts per channel at 4ohms and call it a day. Do you think the upgraded power supply is worth the money? And I keep hearing everyone say that the Maggie's love high current amps. What classifies a high current amp? I don't understand that? What do you look for in a high current amp? Do you think someone here can come up with a list of high current 4ohm or under amps that the Maggie's will play well with? And amps within reason. Like $1500 or lower.
I own a pair of 1.6's and original MMG's. To get the most out of them you need a high wpc and high current amp. The dynamics really come alive. I use to use a Parasound A21 at 400 wpc and 60 peak amps and the 1.6's sounded great. I now use a Pass Labs X250 at 500 wpc but less peak amps. It was a huge step up in sound.My MMG's use to clip a 120 wpc receiver. They did much better with a 250 wpc receiver.If you are looking at PS audio, consider the Stellar 700's which is a nice step up in sound quality and huge step up in power. You can get a great deal on them at Underwood Hifi. Also consider a Van Alstine SET 400. I did a review on it with my Maggies.If you are considering a Class D audio amp, get the largest power supply they offer. I own a Class D audio amp as well. The upgraded PS makes a difference. I am not too impressed by the Class D audio amp. Larry
For only an additional $100, the upgraded power supply was an easy choice for me. That said, my only comparison would to the SDS 254 (with standard power supply) I'd previously owned. Being's that there's such a vast difference in power at 4 ohms ....250 vs. 600, probably not a valid comparison. The SDS 470 just comes across with more authority and sense of ease. The build quality/clean layout of the Classdaudio amps is pretty stunning at this price point. In regard to current drive, that would be a question for Tom at Classdaudio. Like already mentioned though, he's used his amps to drive 3.7's for years.
See..... When I finally get set on picking an amp, I get two totally different replies. You like the Class D Audio amps and Larry in the post before yours did not. But it seems like he is comparing it to some expensive amps. For the money, I bet the Class D Audio amps sound pretty good. But still, I am alway sgoing to wonder what if... I just saved more money and bought something special for the Maggie's and never looked back?
I think that you should buy something special and never look back. Then you won't have upgradeitis in the future for your amp.
I have heard the SET 400 with my Maggies and the S700 on a pair of PSB Synchrony One's. So I really can't compare them.Both sound great. The S700 has a lot more power so it will play louder and it would be great if you ever decide to get a pair of 3.7i's.I love the tone of the SET. It has a fuller mid range. Vocals are sublime. The S700 will have more transparency and wider sound stage I believe. But that is speculative. I prefer a slightly warmer sound with a tonally rich and deep mid range without sacrificing air and transparency.
Well...... I think you just SOLD me on the SET 400. In my room, I SERIOUSLY doubt I am ever going to need the power in the SET 400 let a lone even more power with the S700. I also doubt I would ever step up to the 3.7i's. From the small amount of time I have had with the LRS's on an amp that isn't even opening them up, this could very well be end game for me. At least for a VERY long time. I want to stop chasing the dragon and just be happy. So with that said, I want an amp to make me happy and your comments on the SET 400 about the tone, fuller mid range and and vocals being Sublime. And then without sacrificing air and transparency. Which I would assume the SET 400 doesn't sacrifice in that department. That's all I needed to hear. I have been wanting to give VA stuff a go for awhile now. This gives me a great excuse.
The SET 400 is a safe bet since Frank has a great 30 day return policy. Just remember it will need some break in just like the Maggies need 75 hours. Also, these higher quality amps will expose an inferior preamp and DAC, especially with Maggies that like high quality recordings. What pre and music source will you be using. I run my 1.6's with dual Martin Logan original Dynamo subs. They integrate seamlessly. They are not the most powerful subs but they are fast and musical. I run the Maggies full range (down to 40hz) and the subs crossed over at 45hz. IMHO, over powerful bass will kill the Maggie sound.
By the way, you won't regret the extra power. On dynamic music you will notice the extra headroom.
I have a 12x9 room with 8 foot ceilings. Just moved my Maggie's up here last night and love them. They were in a living room that was open to a kitchen ad hallway and stairs and higher ceilings. They say the Maggie's need space but I like them better in my smaller room.You are using an HT AVR for the Maggie's? Are they going to be used in a home theater application? Just curious, what kind of AVR do you have? I am thinking about trying the Maggie's out in my home theater room.
I just got off the phone with Frank. The ONLY thing that concerns me, even though I am sure he is HIGHLY competent, is he is training a new guy to build the 400's. Yikes. Kind of scares me, I want someone building my amp that has experience with already building them. You run your Maggie's full range down to 40hz? How do you have them crossed over? Is it a setting in your pre-amp? And I am building this system from the ground up. I have components that are capable and will do for now but will be replacing them once the funds are available. But for now I have a Yamaha WXC-50 pre/streamer. And a Denon SACD player. I am keeping it simple. Looking into VA pre's as well as the new Parasound P6, or something from Schiit. I had the Saga and really liked it. Just a good quality CD player is what I am looking for for a source and depending if the pre I buy has a DAC, I might only use the CD player as a transport. Subs will most likely be REL's.And I agree, too much low frequency would not mate well with the clarity, efortless and open sound of the Maggie's.
My 1.6's go down to 40 or 45hz ( I would have to look up the exact number ), so I do not have to set a crossover point on a preamp (My BAT preamp does not have a dedicated crossover or sub out, I just use the second set of preamp outs.) I set the HF cut off on my subs. You only know that the subs are there on bass heavy music if you turn off the subs. If you need a sub or a pair go for a non ported version which integrates better with the Maggies.Franks gear is synergistic. Pairing the SET amp with one of his preamps would be the way to go. I would not worry about him breaking in a new builder. He will take care of you if something is not right. I know Frank personally and his honorable.
