K1000 Room Impression Thread - Page 9

New cages? Would that be to replace dented/damaged originals or get a different design altogether?

Bob I not sure if I thanked you enough for your gracious loan of your RWA sig 30 amp for the room.

For those who have not heard the RWA Sig 30 it is a GREAT amp for k1000s. It may not be as fast or as detailed as the F1 but it is seductive in it's tone. Putting it in to perspective
RWA Sig 30 about $1500
F1 $2000 plus preamp another $1000 (eastern electric minimax) plus another interconnect $100
The Zanden is at least twice the price of the F1
So for the money the RWA for a small amp off the power grid with volume control is a steal.

Moon audio for those that have not seen the silver cable with the silver spades I would love to hear that hardwired and can not get the thought of either that or the SAA cable hardwired out of my head.

there is a thought of removing the metal cages and replacing with a speaker cloth. This is risky as it exposes the drivers but it eliminates the cage rattle some hear. I now beleive that cage rattle may be Tyrion's speaker issue. So far I think only Patrick82 has attempted a grill mod.
If a company came out with a user kit I would purchase one but the k1000s would never leave the house.

Thanks. I thought that there is supposed to be some kind of special 'goop' similar to glue used during assembly that should dampen any vibration from the cage screens against their frames. I haven't heard the rattle from either of my K1000s.

Has anyone tried this 300B .........

...it looks like it would be a good sub for the WE 300b?

Note: S.E.T. Princess 300B tube models are proprietary products of Sophia Electric Inc. Due to popularity of these Princess 300B products, there are many look alike (or early ST model) in the market trying to get a share of success from those who can be easily switched.

Sophia Electric S.E.T. Princess 300B mesh plate tube is the upper class model of the current 300B line (globe shape is still in production). This new tube is using the same 300B plate(as the globe 300B) with stronger plate structure learned from making the original princess tubes. It is a true 300B tube. It will work with all 300B amplifiers (Western Electric 300B direct replacement).

The glass enclosure was from the Princess 206 tube for its unmatched sonic beauty. The shape of glass enclosure does make a major difference. Just thinking of violin's shape, if it gets changed to triangle, the sound character of violin will change for sure.

Sophia Electric engineers have conducted many hours of audition and comparison. In the end the current shape of Princess tube glass enclosure is the most preferred choice sonically. It has more volume and more curved than the old ST. It is not the old ST came back rather it is a carefully crafted, researched new 300B model. The result is a 300B mesh plate tube with super clarity, low distortion and out of this world mid range fullness and liquidity. High frequency extension and sweetness is the first thing you would hear.

Thank you, John. It was my pleasure to participate in the K1000 room. I enjoyed it and learned a lot about my favorite cans.

We all owe you a special thanks for putting the room together.I know how hard you worked to get everything to come together.The result was great.

Well, did people do careful comparison of equinox hardwire and K1000 without hardwire, but without its stock tail? (the attached stump to 4-pin XLR)?

I have the TJ Mesh Plate Premium also by Sophia Electric and they are very fine tubes, but they are not on the same level as the WEs. I would spring for the extra $150 and find some WEs.

There was a lot of listening with the various Moon and SAA tails compared to the hardwired Equinox, but I was not doing it personally. If others did enough to compare, hopefully they will post.

Actually, what I mean is the stock K1000 not using any tail, i.e. the XLR plug directly driven without any tails (vs. hardwired K1000).

Ping and I listened to Al's hardwired SAA and the stock pair with a SAA tail and we felt that it was no contest the hardwire was the way to go. Detail improved as well as instrument timbre. This may be because of three factors

better cable from the can to the tail, elimination of one connection (xlr to xlr) and better solder contact on the driver when the rewire was done with silver bearing solder

So is Richard now a reliable source for hardwire modifications?

If so, I would guess he is the man. Is he ok with cold calls from people he doesn't know (me) requesting hardwires?

I'll add that the Sig 30 benefits from a fast IC. Both Bob and I use a cable designed by the same guy that provides internal wiring and the external cables sold by Red Wine Audio and Omega Speakers (same silver cable as Vinnie's connector for his iMod iPod).

The company is Hudson Audio, the cable line is called AudioPath, and one we have is his top of the line, called 8-wire silver. It comes with Eichmann Silver Bullets and sells for $275 / 1M.

Try this cable, the Signature 30 and a high-end CDP together, and the results may surprise you. Not quite as fast as the F1, but has a very tube-like sound.

Many Sig 30 owners on audiocircle.com have compared the Signature 30 to some very pricey SETs, and report that the Sig 30 holds its own.

Having tried both amps, my personal analogy is that the F1 is a BMW and the Sig 30 is a Lexus. Both good. But different in their appeal. [And no air conditioner required with the Sig 30 ]
