Where did you get your recabled done?

I make all my own cables. And have made some for other people on occasion.

Okay, we're opening a can of worms here, just for you HF'yers.

 

Makers of 5670/2C51 on record:  (we are not going to do a sonic ranking between the valves in each category - way too subjective).

 

Best

WE USA (as 396A) (there are D and O getter versions) - probably the best of the lot but good luck in finding original 'good' ones from reputable sellers for £££

Bendix USA (as 6385) - very rare and hyper expensive

GE 5670 USA - as used in iTUBE
 

Middle

Tung Sol USA

Raytheon USA

 

Worst

Soviet Russia (as 6N3 - mostly Reflektor Saratov, marked in Cyrillic so looks like 6H3)
China (as 6N3)

 

The 5670/2C51 has similar data and application as the later European ECC88 and variants, so European valve makers concentrated on that type of valve.

 

Some valves marked "England" have been sighted, these appear mostly remarked Russian units.

 

Sylvania also made a 5670 which was also seen remarked as "Mullard" but it isn't a true Mullard as they never made this version of valve, just a rebranding job.

 

To conclude, with the iTUBE, we would not spend our hard earned on anything but the WE396A or Bendix USA.

 

 

Note 1 - some background, the 5670/2C51 from a technological point of view, the "premium version" of the 6922 tube. Better design, strong plates, lower microphonics etc etc...

So if you have the 6922, you can roll the valves in your non-iFi device and get better sonics but with the 5670/2C51 family, you are already running with the big guns.

 

Note 2- the 5670 and 6922 have the same physical pins but are not interchangeable as they different fundamental designs. So DO NOT insert a 6922 into the iTUBE. Or vice versa!

Thanks again for the tech info. Very detailed and interesting. I have a budget tube amp for rolling tubes in

Wouldn't a 6385 be too tall to fit in the iTube?

We have not tried the 6385 but the iTube has space for full-size noval tubes (e.g. Soviet 6N3PE) so it should fit, there is even enough heater current available so electrically, it is okay, and probably mechanically too.

 

BUT both WE and Bendix are nowadays extremely overpriced and do not always sound better than the GE5670. The GE5670 is in the top group of a premium tube that is unloved because its pin outs are different.

I did what every responsible adult would do and have spent part of my tax return on an ifi itube.

 

Can't wait to try it out with my turntable set up, as well as my computer set up.

 

Does anyone here have experience using it with an analog set up?  Or do people mostly use it for digital set ups?

Can you please let me know how it turns out with your TT, Terance? Thanks

Hi,

 

We shall also send you an invoice for a new Samsung LED screen. We just read your post first thing after getting into the office this morning and spat coffee all over the screen. :smile:

 

Seriously, if you get a chance, ask your dealer to demo the iPhono+ iTube. There is no going back.

 

You just made our day.

T-minus 1 day: Crowd-Design (NOT Crowd-Funding) of the micro iDSD


Guys and gals. ONE more day left for all entries to be submitted. There are a few who have contributed a heck of a lot but at the other end, there are some neck and neck entries.

It is really difficult to to pick those at the moment as it is a real close-call.

If you are one of those, keep chiming in as it is likely to make a difference.

See you on the other side!

Hey no problem!

 

I don't have a dealer in my area and purchased a demo unit from Music Direct.

 

Currently, I really like my phono stage, but I can see myself picking up your dac in the future! (if I like the itube).

post #269 of 295

So, it may be a little early to give impressions, but I've been using my iFi iTube for about an hour now.  It was a demo unit, so I am guessing that it's had some hours put on it. 

 

After listening to some audio files on my computer I've decided that this thing makes everything sound like vinyl records.  That's a very good thing.  Considering I'm using a cheapy $15 Chinese USB DAC, getting this sensation from my digital music is quite surprising.  I'm not using the 3D sound switch with my headphones, but I do have the digital switch turned on.

 

I will report back in a few days with further findings.  For now, I'm a pretty satisfied customer and hopefully that makes up for the coffee covered computer monitors!

hi,

 

I am planning to get itube. I am new to tube audio and have not heard any tube based product before. I am using an entry level DAC/amp and don't like the treble it produces. I have 2 questions. :

 

1. If I use itube as buffer stage in my chain, will it reduce sibilance in treble happy cans (eg beyerdynamic dt880)? Also will it make it sound delicate and smooth? Right now I find treble to be metallic and harsh.

 

2. If I use itube as buffer stage, does amount of gain control how tubey sound I get?

 

Again I have never heard tube based products, and if I can control how much characteristic tube sound I get, that'll be great.

 

I will probably use my old DAC > itube >  ican (probably)
