K1000 vs R10 ... - Page 8

post #106 of 198
Why not running the heapdhones in dualmono configuration, instead of "balanced"??? AFAIK balanced only is an advantage for long runs, where the loss is really noticeably, other that that you have the doiuble of everyhting, from parts to the noise.....

It's been discussed quite a few times, do a search on "benefits balanced" or something like that. If I recall one of the benefits is increased slew rate.

I know that, and it is true, but also it is true that you also get the double of the noise at that expense in the same circuit and the double of parts, with the disadvantage of introducing more coloration, the double indeed...many manufacturers do not agree with such statements and these so called "benefits"....BTW...

Mostly the balanced equipment is used in professional world, and just because of the long distances, and where the noise exposure is a lot more, but for short distances not even in that field they use balanced....

Rather than derail the thread into an argument about balancing, how about we just agree to disagree.

Agreed, but BTW the thread is about ten posts or more out of topic, and it was derailed already into the balanced/unbalanced issue by other members not us. If you read the inital posts, the original intention was a comparison of the R-10 and K-1000 in an unbalanced setup (Nik's) and not to argue if it is better to try the heapdhones in a balanced setup or not....

Perhaps a Balanced R10 thread could be started and have Mikhail chime in?

Either that, or I'll be finding out for myself soon.

If I get off my @ss and finish my DynaMid.

Of course I'll be happy to help out by chipping in my opinion as I can, but your ears are the only ones that count. Hirsch may be in a position to do some of these comparisons soon as it seems that he's on track for an ES-1 (based on his earlier posts) and already has quite a bit of listening time with the SDS-XLR. But it's your ears that count! (Or did I already say that? )

And seriously, the K1000/Ear V20 is an awesome combo to my ears but based on your impressions of the K1000's they may not ever "do it" for you. I hope I'm not "touting" the V20 too much because there is always the "new toy syndrome" that we all suffer from at times, which tends to cause a temporary loss of objectivity no matter how we might think we're fighting it. If 3 months or 6 months later I'm still blown away then that will be a different matter. But by then I'll be on to my new vinyl rig!

I hope that these answers will also follow from listening sessions at the forthcoming National Head-Fi Meet in April.
I think we're ALL looking forward to the AWESOME listening opportunities that the National Meet will provide! There should be a TON of opinions floating around afterwards. I can't even begin to imagine how long that "meet impressions" thread will be! We probably should break it down into seperate threads by major categories, although that may prove to be impossible to administer (i.e., portables, dynamic, electrostatic). I think we'll have to go into that event with our individual listening game plans in mind and have notebooks handy to record our impressions as accurately as possible. You want to talk about a bunch of kids in a candy store! There will be WAY too much gear on hand to even come close to listening to it all. Only the "great" agile_one could pull something like that off!!!

I think that the K1000 is a "dangerous" cans, because is a toatlly different kind of listening way with headphones.

My impression is tha if we start to listen for a long time with them, than will be not simple to come "back" for a "traditional" cans, dynamic or electrostatic.

This do not means nothing about quality of the K1000, just a different way to have music from headphones.

IMO: even different by speakers, I find the R10 more speaker like sound than K1000. But, sure, the K1000's advantages do not have any other cans.

Best!

Yep. Lots of things going on now. Balanced R10 coming. ES1 coming. SDS-XLR going to be recapped, rebiased and power regulation brought to current specs. I'm probably going to be too busy listening to post

Incidentally, SDS-XLR with 5687 output tubes makes a very nice amp for K-1000. I haven't found the right gain tube yet, though.

Hirsch - You're now the focus of our high-end headphone world, and I'm anxiously looking forward to your future postings. BTW, have you ever directly compared an ES-1 to an HEV90? Also, have you had a chance to hear a balanced R10 powered by the SDS-XLR? And, which of your two R10s is being modified to the balance mode?

I just have only one R10 unbalanced...

K1000 + Valhalla = Heaven

After I connected Nordost Valhalla power cord into my amp it was a match made in heaven. It sounded both warm and airy at the same time!

After some Solid-tech isolation devices I got even more warmth and it feels like I'm sitting in a sauna, and I'm running without tubes.

There are no problems with K1000 other than bass roll-off from 50 to 30 Hz which is less fatiguing for me, with K501 I got sick in my stomach from 40 Hz frequencies, how can you enjoy music when vomiting? The roll-off from K1000 is perfect for me.

Hi Piotr Ryka,

Finally I have received the GEC KT66 and you was right, these are the best tubes in my amp, even better than RCA 6l6gc black plate. Thanks!

Best!

I am glad, You are happy with KT66.
There are two kinds of them, I forgot to tell You - "Gray Coated Glass" and "Clear Glass". This "Gray Coated" are better. Which You have?
