new ET-7, the replacement for the ET-5

Post by roberto » Fri Jul 28, 2017 7:46 pm

[*]Dear friends,
I just ordered one of the new preamplifier model ET-7. Spoke with the designer Mr. Jeff Fischel at Conrad Johnson, and he said:

We are proud to announce the new ET-7. It's design is based as the Gat 2, but at affordable price. Has the same principle with the regulated power supply, and using a single triode amplifier. It uses the same vishay resistors and teflon capacitors.

Very cool. Would love to hear your thoughts when you get it. Interesting I don't see any information about the unit on their website.

Jeff told me that they are working on it, and the page will be up-dated soon. Could you see the attachment that I downloaded?
Regards,
Roberto.

Hola amigos! I just got the ET-7 preamp and the first thing that I had noticed is that it weights a lot. Also, it is big! I am going to hook it to my system and I will tell you my first findings.

Happy listening!
Roberto.

First Impressions: Clean, transparent, need time to break in, but I did know this before. Has very high extension on both sides, highs and lows, there is no dirt at all. Voices are projected very good, and has the tonal balance characteristic of C-J. There are a lot of air in the wind instruments. The violin is with the right size, and it does gives love. Cymbals are crystal clear. It is bringing more resolution than my Sonic Frontiers line 3. Its easy to choose any instrument at the recording and listen what the musician is playing along.
The fingering at the guitar is very, very good and easy to understand. Lee Ritenour is playing beautifully.
With the percussion, has a lot of dynamics. The speed of the sticks on the drums are real...actually, you can hear how fast they are moving and hitting the drums. Very impressive here.
The sax has an incredible warmth...it is a truly sax player what I am having here.
The hammond Organ B-3 you can hear the key contacts just before the musical note arrives...very interesting.
Easy to tell when there is a double bass player or when the organ bass notes are.
A very nice balance with the level of the instruments and voices...but what it amused me is TRANSPARENCY!'

In the next 15 days or so, I will keep you posted about its overall sound.
Happy listening!

Congratulations Roberto and thanks for your impressions.

Can you tell us what tube or tubes it uses? single electro harmonix 6922? or Philips PCC88 maybe? If you are inclined to open up the case, any chance of some pictures of the insides?

Anthony

Hola. I promise to you that the 21or 22 I will post the inside pics. Right now I am in a work business travel.

Yes, it's a 6922. Also, it's beautifully crafted inside. I will poste a pic inside Anthony.

Happy listening!

How much gain does the ET-7 have? The spec for the ET-5 is 25 db, which probably accounts for the relatively shortened tube life before noise. I love my ET-5, btw. Just wish it were not so hard on the tube. At least it is only one tube. If the ET-7 gain spec is lower, say 20 db or so, we can speculate that tube life will be better.

Hola Bill...I do believe that the ET-7 is a simpler design than the ET-5. The look inside is clean. I did open it to put the rubber o-rings to the tube.
The sound right now is a little bright, because it needs a lot of break in time...I do know that you do know this, right?

The look inside looks an expensive crafted, with super good quality parts.

Happy listening!

Hi Roberto,

Thanks for your response. I do not want to get into debate, but will just simply state that I believe break in is a big myth as it affects the sound quality of high quality equipment. If you want to believe that you can hear a sound improvement after several hundred hours that is your prerogative. Would you look in your owner's manual and provide the specification for gain? Thanks in advance.

Bill

Bill, I assure you that you can hear a difference...The lower mid-range section of the music is too weak, and the upper bass...this happened too with my previous ET-5. I am not talking 800 hours, I do not believe it too. But this is true for the teflon capacitors. The gain is lower than the ET-5. The unit came without the instructions manual, I will get it soon.
But, I do believe that specs are about the same as the ET-5. It uses only one tube, and has teflon and metal foil resistors. What I think it's different, is at the regulated power supply. The power supply is a newer design, following the same approach that the Gats2 has.
Out of the box, you have a brush-stroke of what it is capable off, it is crystal clear, with the right timbre of the instruments and voices...I really do like a lot what I am hearing, but it needs a little more time...just to settle the electronics...not a big deal, but an improved difference to my ears.
Happy listening
