I'm hoping to eventually roll in something else and keep this quad as a backup anyway.

 

Was always my understanding that the Leben did not require matched tubes, so that's good verification.  In any case, what a lot of sellers call "matched" really aren't necessarily, as real matching requires more than just an average tube tester.

The CS300XS amp is self biased and will adjust for mismatched tubes, that said the more closely both tubes in one channel are matched the better. Better yet all 4 matched tubes in the same amp.

 

BTW, I use some pretty high end laboratory qualty tube testers and when testing the original 4 EL84 tubes that Leben supplied with my CS300XS it seems so does Leben as all 4 of these tubes matched exactly.

Where are you guys finding this 6.4mm x 30mm size?  I looked on Furutech's own site, Acoustic Sounds, Music Direct, VH Audio, eBay, etc.  Am I blind?

 

 

Nope, not blind.  Just a moron!  rolleyes.gif   I applied a bit more force and eureka!  It's in.  Heh, I'm so afraid of hurting my precious Leben that I might be *slightly* overly careful.

I have a set of 3 sovteks and a pair of the smaller sovteks if anyone needs them for their Leben. I don't need them so if any one does, just PM.

So how does it sound? Does that expensive little fuse make that much of a difference? I would love to hear from someone who let some non-audiophile friends or family listen to a song on the leben before change, then immediately after change and give their impressions.

In the past I had read outlandish claims by writters in various hi fi magazines about green markers on CDs, or de-magnitizing a CD, and then suddenly the resolution is so much better they can hear a mouse fart in the back rows of the philharmonic during their favourite version of the 1812 amongst the cannon blasts that they had never heard before, etc, etc,. Everyone is going to hear an improvement who spent $70 on the upgrade, but a non-audiophile who has no vested interest is more likely to say it like it is.

Thanks

Nope, can't tell a difference.  That said, a before-and-after comparison is obviously much more difficult than a side-by-side comparison.  There might be a minor improvement to the sound that my short term memory can't differentiate, and I'm ok with forking out $70 for the warm fuzzy feeling that I might be better off than I was before.  I certainly don't recommend that attitude to people who are short on cash, however.

 

Edit: not that I'm rolling in cash, as my overly-cautious installation of the fuse proves.  biggrin.gif  I just want to be sure I'm getting the most out of my Leben, and I'm willing to take the advice of the more experienced Head-Fi'ers who attest to the fuse making a difference.  My ears might not be as finely tuned as theirs.

That requires down time and cooling off between fuse changes so at least several minutes would be required - then warmup time. Solution is to have two CS300XS amps hooked up to the same sources and speakers. If you can't hear the difference with your current amp just play it with the fuse in and forget about it.

Not exactly starting well...

 

 

Here's the issue...When the balance control is set to 'Normal' the center is completely screwed. By that I mean imagine yourself at one end of a long hallway. The singer is way down at the end, and the band is right beside you. When moved to far right or far left it comes into focus. 

 

I've also noticed that there is a noticeable hum that can be heard when the balance knob is grasped. Less noticeable when on 'Normal', very obvious to the left, and somewhat obvious to the right. 

 

Tried all variables before coming to this conclusion, but it's definitely the amp. The brand. new. god. damn. $4000. amp.

 

EDIT: The one I waited 1.5 months for.

 

I felt your pain about 1.5 yr. backwards in time within this thread.  In my case I had bought the dealer's model to avoid waiting 2 months for a new unit, and the dealer's unit turned out to have balance issues and a problem with the headphone out.  My dealer simply got me a new one and that resolved the issue.  I'm glad your issue was eventually sorted out as well.  

 

I have seen some frustration aimed at Leben over some of the recent reliability issues, but now I begin to wonder if there simply isn't some rough handling causing many of the issues due to the long distance transit from Japan.  In your case it was a ground wire, and while I never received a 'post mortem' on my original unit, it sure sounds familiar having read about yours.

 

Being a lifelong user of tube gear, hi-fi and guitar amps, it certainly isn't uncommon to see shipping mishaps with tubes, fuses, wires, etc.  In the end, my experience with my Leben dealer and with the importer was excellent.  My input to Tone Imports would be better QA by the importer during receiving each unit.  I think perhaps this is left to the dealer and perhaps the consumer due to the transit and waiting period being long enough as it is.  Otherwise, the mishap was handled exactly like it should have been by a solid dealer / importer standing behind the product.  I was satisfied in the end and very much enjoy my CS300XS.

I'm want to upgrade my speakers and plan to spend somewhere around $3000-$3,500 US.  I'm pretty much set on getting a BBC style, stand-mounted, monitor speaker and have read some very good things about the pairing of Leben with ProAc, specifically the Response D Two, though I think the Leben in many of these cases was the CS600.  

 

Harbeth sounds interesting, but at my self-imposed spending limit, I would think the 7es3 is the likely model.  However, in reading some of Stereophile's comments, I think they rated the ProAc a little higher in terms of full range sound and effortless pairing with all types of music.  That's pretty much describing my criteria - old school punk to jazz to acoustic guitar.

 

I like the fact that the ProAc Studio 110 is rated well by a fellow Head-Fi-er.  I like the fact that many from 6Moons to Stereophile rate the ProAc Response D Two pretty high.  But I keep seeing the Harbeth recommendation being made, including by MorbidToaster recently and many others in the past.  

 

My listening room is fairly small at 12 x 16 or so.  I'm looking for good recommendations given my spending limit, and predilection for a BBC monitor style speaker.  However, I'm trying to get better bass impact than I have now from an older set of B&W 601 speakers.

 

At risk of inviting the gamut of recommendations of speaker manufacturers, let's limit it to BBC style and realize I have auditioned the Leben Importer's recommended Devore 3XL, and while they sounded good, I was not blown away enough to consider them for purchase.

Impression so far. Did not know 15W can drive my Proac's so well.

TBH I'm worried about the HL5 being too big for our new apartment (plans have changed and we are now getting a smaller place) and am considering (after trying them in the new place of course) switching to the 30.1. We'll just have to see. Room treatment can fix some issues but in our current place they're really, really bassy.

As for the 3XL, I really liked them for Jazz (Leven was nice with them but Line Magnetic stuff was even better). But they didn't do much for me with other genres. The Harbeths were definitely better all rounders.

Your room is bigger than mine is it will be.

I'm reading some very positive reviews of the Harbeth P3esr too.  Given my room size and closer placement to the wall, these seem like a good pairing with the Leben.  I wonder if bass response will be adequate?

post #1677 of 2118

Their extension leaves a lot to be desired but otherwise they're fantastic. I was really impressed when I heard them because of how tiny they are.

I am surprised you cannot tell the difference. To me it was one of the most satisfying upgrade when I changed to Furutech's 6 months ago.

 

I wonder if the improvement is a function of the tubes + the fuse...given varying levels of success with the fuse upgrade.

post #1679 of 2118

What tubes are you using, BugleBoy?  I currently have Mullard EL84s and Sylvania blackplate triple mica 5751s (all NOS).  I'm thinking about expanding my tube collection in the near future and plan to start with Sylvania blackplate EL84s and Amperex Bugleboy 12AX7s.

 

Edit: just read your signature and saw the Raytheon/Amperex tube combo.  Might give one/both of those a try too if I can find them.

post #1680 of 2118

Yes...after trying various tube combo I have settled for Raytheon 7729 or 5751 & Amperex or Philips Miniwatt EL84's (both with d-getters).
