Last time I visited rudistor web site, I found highest model is RP6-DQ, but I have visited the site today RP-6DQ has disappeared and RP5.1 was highest. Why RP-6DQ has been removed in web site? Another question, Is there big difference between RP5.1 and RP5CAV? Please answer. Thanks.

Is this sale for preparation of next amp line-up which will replace max, blockhead, etc or just because they have too many stock as a rumor said? Other rumour also said headroom is also going to produce and sell tube amp. is it right?

I listened more carefully and compared with rs-1 in main system after I got home. It seems that ms-2 have narrower staging than rs-1 and rs-1 sounded more refined. ms-2's high was not so harshing as sr-325. I'm wating for grado divide cable to arrive for better comparison. And it is...

I just have received MS-2 and frankly I cannot tell difference with rs-1 that is burnt-in. I just have listened and compared it quite a while. How long it takes for MS-2 to be burnt-in? and what is different in sound after burn-in? I have to buy it or should return to seller after 7 days and...

To me 4G is small. All beatles albums with 192k exceed 1G. Anybody knows if apple has a plan for ipod mini with larger hdd? Please answer

Quote: Originally posted by Permonic however I am waiting for more reviews of PS-1's and considering HP-1's, HP-2's for the future too. I know PS-1, MS-Pro and what is HP-1, HP-2 and HP-1000? Are those also made by grado or OEM by grado?

I own rs-1 and I have owned and heard only rs-1 and sr-325. And as far as I heard, rs-2 has some quality diferrent from rs-1 and sr-225 has flattest freq response in grado series. I wonder if I need to get rs-2 or sr-225 or I just need to have only top model and getting other model is just...

I heard hd650 stock cable was improved compared to hd600 stock cable. and I think it is thicker than hd600 cable. And replacement of hd650 cable can improve sound like hd600? I also have hd600 and Cardas cable but I heard here Cardas cable is not good for hd650. I want to know if cable...

Hi. I wonder which DAC is used in grace 901 I saw somewhere DAC of 901 is good but I can't see difference with DAC of arcam cd72t. As far as I listened, only volume level is little higher than analog connection. I mean when arcam 72t and grace 901 is connected by both analog unbalance and...

I'm considering buying corda prehead or max I'm using ra-1 for rs-1 and corda ha-1 for hd600 and wondering upgrade of amp can improve sound. I saw someone wrote max is not better than ra-1 for grados. is it true? I wonder upgrade of amp can really improve sound and if so which amp to choose...

Does hd600 replacement cable sounds better than original cable? I don't belive sound improvement by power cable but somewhat belive in good interconnector though I have not used many interconnector. I could distinguish difference between $1, $20 and $100 interconnectors. I wonder more...

I am satisfied with my headphone amps. corda ha-1 for hd600, ra-1 for rs-1 And for now only CDP is not so satisfactory.. cd72t. I am going to replace it with cd33t or 23t and I wonder headroom max is how much better. is it worth the price? It's price is 4~6 times that of ra-1 and corda ha-1...

I omitted something. When I change phones backward or chage interconnector, phenomenon is same. right ear feels wider staging than left. and when I hear my beatles mono CDs, I feel no difference between left and right. In this case, you mean my ear is some asymmetric?

I feel difference in staging between left and right ear. I feel this more when I am using ra-1 and rs-1 rather than corda and hd600. I wonder whether this is for my asymmetic ear or wrong equipment. I feel wider stage in right ear that left. and left is somewhat closer that right. Is there...
