@STRIKER

medyo malayo na ata if you use the tuner for comparison to a cd. :)

sir eto po claim nyo.....
so you mean given that everything is the same, if i play music from the tuner function of my receiver and i use a cd.... based on your claim they should sound the same?

medyo hindi nag-connect.  medyo lang.  pero kaya pala nag o-object ka. 

or to be more specific if i use a branded RCA and compare it with a generic freebie RCA they should sound the same?

if there is no interference on the crappy free RCA, they should sound the same.

please read yung matrixhifi that i linked.  they used wooden bangko, crappy RCA and cheapy (but well designed) amp - no one was able to distinguish

everything is the same, so even the source should be. sound from the receiver and one playing from a cdp will definitely have audible difference.

as long as you make sure your amp and other equipment is capable, all SQ is 50% speaker and 50% your room acoustics 0% amp 0% cables 0% player 0% preamp
...

 8)

Indeed ... and I may add ... the others should be the one mindful of their claims ... and without any doubt, Rotel 1077 is also one of them, a good power amplifier!

Anybody with this power amplifier?  Any issues with heat? Ok kaya eto i-pair sa Dali Ikon speakers ko?

Doc Jun - last month in Sing I was offered a Rotel RMB 1085 class D 100wpcx5 for S$1300 - napaisip ako eh ;D
Too bad, I didnt have time to audition it.

Since the RMB 1077 has 2ch more (7ch), then I would say baka nasa S$2k cguro ang presyo ::)

....

am not mike c ... but will answer ur q ... player will not impact on your sq if you use tuner  ;D

kidding aside, mike c is down right into the issue. My equation is 1/3 - 1/3 - 1/3 (source program, not player - speaker - listening room).

So if it is your CD vs tuner, it has difference.

But for your audiophile gear, 50-50 (speaker/listening room). The trash you load to your CD player, is the trash you will hear ++distortion of your speakers & listening room. Even if you change your player, it will be the same trash you will hear with the ++D in it. The amp/pre-amp/player being the good guys in the chain.


...
or to be more specific if i use a branded RCA and compare it with a generic freebie RCA they should sound the same?
...

This is a very old barbers' story sir. Proven to be a non-issue in SQ, unless you are comparing dilapidated cables - hands up na ko!

Ang mahal talga dito sa Asia region mga gears.. Sa Audiogon.com nasa $1,200.00 ang used 1077.. Kaso ang problem ang warranty if ever may problem.. Tapos 110-120v pa pag galing sa US..  >:( >:( >:(  Although sabi naman sa Rotel.com, you can actually convert the 120v to 220-240v by tweaking something inside.. un lang mag hire ka pa ng magaling na technician for that..

I find the highs polite on the ice modules used in the rotels, advantage would be space and power consumption per watt :) There are other brands to consider as far as class d is concerned, also there are still far more expensive linear amps as far as i'm concerned.

If i had a rotel 1075 i would fix my speaker placement and room acoustics before changing my amps.

As for biamping, it depends if the speaker is designed for it, you might get better results switching to a higher power amp instead. Ideally biamping requres two amps with the same gain and an outboard electronic crossover.

Doc - ganyan talaga going ng preowned. But thats an amp - sabi nga ni brader matz, amps last a lifetime ;)

About the 110v-220v, sabi nga sa akin ni jojod - the parts made for the 220v countries & 110v countries is basically the same part lang as Rotel's Toroidal can take both powers. Its just a matter of tapping wires.

When I planned on buying a Rotel poweramp sa states, I contacted George Miller of B&W Group of companies, USA. The conversion of 110v to 220v is straightforward. All you need is a tech Manual/schematic diagram of the specific amp - which Mr. Miller sent thru email.

As for the conversion - kayang-kaya yan ni Jojod  ;) ;D

Below is the email of Mr. Miller to my question about the conversion:


Hi Mardon;
 
Converting Rotel equipment for 220 volt operation is a fairly simple procedure.
 
If you can give me the model number perhaps I can give you some more specific information.
 
If you would like to do the conversion yourself I can send you the tech manual however this would void you warranty if it still applies.
I would also recommend that you be familiar with voltage conversions and have a good deal of technical knowledge. On a scale of “1” to “10” I would rate a voltage conversion as a “7”.
 
 
Best Regards;

George Miller

If however you do the conversion yourself - it voids the warranty. Ipagawa mo sa Rotel dealer dito para hindi void......but price may be steep ::)

Magkano kaya ang voltage conversion dito ng Rotel Power Amp?  Have you done the conversion yourself as per the email of Miller?  Magkano kaya rate ni JoJoD?   ;D ;D ;D  Gustong-gusto ko na bilhin yong nasa Audiogon.com..

Doc - if conversion lang problem mo, no worries - madali lang yan. I already saw the tech manual & could understand a bit kahit wala ako alam sa electronics.
Inaantay pa nga namin yung amp ko eh - mukang delayed ang barko :P

Talk to Jojod about it - I'm sure madaling kausap yan si brader ;) Bigyan mo lang ng chicks......ay este, chiksilog yan magkakasundo na kayo ahihihihi :D ;D

to be honest, majority of my decision in buying the 1077 was because of what I read on htguide.com (rotel sub forum) - sabi nila super ganda daw nito tumunog, better than the 1095 and any other rotel amp save the 1090.  baka pagtimplahin ka pa ng kape.  when i got it, i found that I prefer more power for more SPL than the supposed better SQ.  the 1095 has 200wpc, though still less than what i am currently using (360wpc) it would still have been a better investment (for me) since my 1077 is now parked in my bedroom with just two channels being used.
