thanks for the rec., Spektrograf.
I'll look into that...

got it, thanks for the info.

For the amps, I recommend classic used Hafler gear. The DH-110 preamp and the DH-220 power amp can be bought for a song off ebay, and these are very good, and even better with just a couple of minor mods (fit better connectors, and hop-up the power amp rail capacitors, a few judicious coupling capacitor upgrades here and there, etc.).

I also second the Sunfire True Subwoofer Jr recommendation. I have the full-sized True Sub and a friend has the Jr. Their diminutive sizes are very decor- and spouse-friendly, yet they deliver unbelievably deep bass.

Hi All!

AMB's suggestion of used Hafler gear is a good one too. They made good stuff for reasonable money and there is a bunch still out there going strong. There are companies that modify and improve these beasts too. Nice catch AMB!

Before David Hafler started the company of the same name, he founded Dynaco and one of their last solid state power amp offerings was the Stereo 400 which was designed by James Bongiorno who also founded Ampzilla and SUMO.

There were three vintages of Andromedas. Bongiorno designed the first while the other two were launched after he left. All are balanced AB designs capable of in excess of 200 watts per side into 8 ohms. The last (Andromeda III I believe) was the nicest looking cosmetically but all will get the job done.

Very best regards,
Steve

DH-110 preamp and DH-220 power amp? how much would that cost? in average?

the next time I wanna to get sub, I'll look into that....
seems like it is a nice sub

ebay prices vary, but you should be able to get good examples of the DH-110 preamp for less than $100 and the DH-220 power amp (115W/ch) for less than $200. If you want more power, the DH-500 beasty (250W/ch) is also great. Why not search ebay and have a look?

yep, thanks. I found some on sale at ebay.
but, as I mentioned before, her dad do not want to take the risk of having second hand electronic stuffs... so what can i do... hehehe
even though, its look like a good deal with that price point..

I Just got the chance to talk with his dad last night, and he seems to be getting more interest with this... which make him feel good why he have to spend this much of money

Update on the size of the room that he is going to put all these gears...

room size is about: W x L : 5metres x 5metres

currently, the room is not there yet.. but this is the plan of having one.

I think the room will be finished on the end of this year since its a new house

More update: he agree on having 2CH setup instead of going for 5CH setup. therefore, I'm pretty sure at this stage going to buy Rotel RA-1062 to drive the MMG.

any recommendations on anything... is welcomed

thanks guys for the help.

If you want to know what lots of users recommend for any model of Magneplanar ever built, visit: http://www.audioasylum.com/forums/MUG/bbs.html

The Planar "asylum" on AA is pretty much the Magneplanar User's Group (although they also talk about planars from other manufacturers). Search the archives or just fire away with your questions and you will be swamped with info and opinions on every and any aspect of Maggies (which by the way are very good speakers).

forgot to mention this on the Update...

Most of the time, the setup will be used for karaoke and music. I just want to make sure (before i order them) that MMG is a perfect match or close to it for karaoke, compare with dynamic speakers.

noob here, I have no idea on if there will be a difference if the setup will be use either for karaoke or music....

thanks..

ok. thanks

He's in for a lot of trouble if his room is 5mx5m square. Expect lots of mid-bass build-up since two of the walls are parallel giving a 2 dimension build-up of standing waves both on the length and width of the room, along with some axial mode buildup. If it's not built, maybe he can change the dimensions still. If not... SAVE SOME MONEY FOR ACOUSTIC TREATMENT. That mid-bass mud will be most annoying when you integrate a sub, depending on where you set your crossover point.

Also, (this is just my 2c), but with karaoke, the music is generally highly compressed and lowQ in nature, so I don't think electrostatics will make or break the fun of a session... maybe more the singer's voice... or how much everyone has drunk already... will have more impact on SQ.

Here's a cheap way to do acoustic treatment:
Ethan Winer's Acoustics FAQ

What he'll be looking for is bass-traping primarily before anything else. Depending on material and layout, other needs may arise. At this point, this is beyond the scope of a Head-fi thread. I'd post over to Audio Asylum to get more in depth about room acoustics.

thanks for the links.
Audio Asylum forum is like a mess compare to this forum. Probably I have to get used with it.

the Room is not there, its just a plan. I guess I need to read up about room acoustice and recommend the room size to her dad. this Learning things getting better and better

about the mid-bass build-up thinggy... I have no idea whats that mean.. noob here... I need to read more...

about karaoke, yes.. I agree on you about the low quality of the music... but will make any difference if I use dynamic speakers instead of MMG? anyone had any experience with this?

Please take some time to read the link to Ethan Winer's Acoustics FAQ above. It will explain your questions and help guide you along the way on room acoustics. If you need further explanation (more of the same stuff really), a quick search on Google turned up this guy's page on room ratios and acoustics: link. Better yet, have your gf's dad hire an acoustics consultant for a few hours and have him work with the architect.

If you find Audio Asylum too unwieldy, I'd suggest doing a search on Google Groups for room ratios and start doing A LOT of reading. The information is out there, you just gotta go search for it. If you still need help, post up on rec.audio.high-end and you should get plenty of responses on all you seek. Good luck!

Excellent!!

I'm sure that I'm going to be very busy doing the reading this week.. heheh

Unfortunately, I never heard if an 'Acoustics consultant' exist in my place (Indonesia). there probably only some lousy or amateur consultant, and i wont even called them consultant. it just some guys have a lot of experience in speaker thinggy.. because he is the one who sell it..
But overall, its not a bad idea to see what they can recommend on room acoustics... they probably know! which i'm going to be surprised.

Thanks a lot spektrograf... u surely help me a lot on this thing.

and also chicagoPhil... and other members...
