Yes, it should be awesome.     The Amp is beautiful sounding.  It should be a great match .   The Preamp will have 3 inputs and two parallel outputs to bi-amp or drive a sub which I will do.  

@oddiofyl 

Given Matt’s experience and talent, I believe that this is going to be a very exceptional DHT Line stage for you. The Leto will face a major challenge.😊

Hi Charles , 

it will use a 101d and a 84 rectifier.  It will use an encoder / relay volume with LED display. and remote

I was talking to Matt earlier this year about a preamp project he was working on….  This is the one.   

Wow! 
Which DHT tube will be utilized? My Line stage uses the 101D DHT and it is superb. Needless to say I am very curious as to how you will find it compared with your Zesto Leto Line stage. I love my DHT Line stage and 300b SET pairing.

Charles

I am enjoying  this amp so much I am having Matt build me a DHT Line Stage.    

The WE is an integrated,  the Toolshed is a power amp....sure, it has volume trim and 2 inputs so it can be either....  I think it is best served with a great preamp driving it though

“Beauty is in the eye of the beholder”

True, and always will be the case. The W.E. amplifier is certainly a very different aesthetic (I don’t like the front panel big screen, but that’s just me 😊) I don’t find that it is more attractive than the Toolshed 300b SET amplifier appearance. Horses for courses folks.

 

This thread is about the Toolshed 300b.  Not vapor ware....Has anyone even seen the WE91e in person ?   Anyone here own one ?  Please chime in if you do. They have been promising this amp for a long time and it's still "coming soon"   Either way, it's way out of my price range.  It's more than 2x the price , so if you buy one let us know how it is.... beauty IS in the eye of the beer holder ....that thing is ugly in my eyes.

This amp sounds sublime.... So it's looks are a little polarizing, that's ok, the fit and finish is excellent,  this is execution on a high level.   I love it , pics do not do it justice .  

As far as the WE amp I think that's a little weird looking myself.   Should have had a more retro industrial look and analog meters .  

I'll take a simple point to point wiring design and analog volume  over a PCB and volume encoder any day.   The WE Monos look cool,  the 91e ?  fugly.

Three year warranty on WE amp,  and 5 years on tubes is a joke right?   Toolshed amps have a lifetime warranty , although I doubt I will ever have to exercise it.  

 

Wonder how it compares to the Western Electric amp. That thing is gorgeous as it should be for about 2X the money.  Dont think I could live with the looks of the toolshed unfortunately.  Beauty is in the eye of the beholder for sure.

Synergy has a lot to do with good sound,  the Zesto / Toolshed  pairing is such a great match.    When I got the Zesto , it revealed how good those Quicksilvers are. 

As great as those Mid Monos have been,, the Toolshed 300b is in a completely different league.   It is amazing in it's ability to render a three dimensional image .   I have spent about 5 or 6 hours a night since Sunday playing song after song .   Some that I'm very familiar with, some are completely new to me .   

My mental notes while listening have been ;  amazing clarity , huge image extending way beyond the speakers.  They disappear.    Clarity , accuracy,  realism, lifelike,  are all things that i keep saying in my head.   

Little sounds like tapping the top of a guitar,   the inhale / exhale as a singer projects,  the ambiance of the venue are all revealed with this amp.  

Bass is solid and incredibly tight,  and deep.  I keep thinking this is only 7 watts?   Most surprising are the lower registers of a piano.   

There is a connection to the music that is so engaging that I am completely not thinking about the hardware,  I am thinking about what song I am going to play next.   

I can say without reservation that this amp was worth the wait and worth the money.    

Ever been at that point in time where your system sounds so good that you are afraid to make any changes? This is where I am at right now. That DAC was a solid purchase. It is very engaging and you want to just keep listening.Which is what I’m still doing at 1215 on a work night

Yes, I completely understand . This is why I’ve had the same preamplifier, amplifier and speakers unchanged since 2009. Genuinely happy and satisfied with them. Same situation with my DAC (Bought new in 2010) it just presents music beautifully.

I’ve heard a number of other DACs in the interim. None compelling enough to make a change for. The Lab 12 DAC Reference is intriguing and seems like the real deal. I appreciate your feedback/impressions.

Charles

I read about it somewhere and learned that Fidelis in Nashua NH was the distributor.  I had a few days off at the beginning of June and gave them a call.   I asked if they took different category trades and they said sure come on up.   So I packed up my CJ Classic preamp that I was no longer using and took a ride up. 

I listened to it in a LAB 12 system driving Fyne speakers .   They offered me a generous trade that almost paid for half so it was a no brainer

It is built like a tank compared to a lot of stuff at this price or even above.   It sounds fantastic in this system.

@oddiofyl 

I am gaining awareness about the Lab 12 DAC Reference  made in Greece. Seems to be very well received. How did you happen to come across it?

Charles 

Thank you larsman ! Several times I have thought to myself “amazing clarity”. I actually bought a second pair because I was afraid they might change the recipe or they would become unobtainium

Great looking amp! Enjoy those 300B's - I've got an Eddie Current Studio B headphone amp with WE 300B tubes, and my Susvara headphones are aural crack through that setup. So easy to listen for hours and hours.....

Thanks Charles !    Due to Covid , two years of doing nothing allowed me buy a few nice toys.  Also ,  I'm very fortunate that my company pays for my car, insurance, gas , repairs , and phone.   It allows me to have a little play money..... 

My DAC puts out a fixed 2.5 volts ,  so at some point I  may try connecting it directly to Source 2 and use the gain as volume.  Something tells me I'll prefer the preamp in place but I want to try it.   
 

Yep, I’d also compare the DAC direct versus active preamplifier. I’m inclined to believe that the Zesto will be hard to beat.😊 You’ve put together a quite lovely audio system.

Charles

Charles, I do use the EquiTech for most components but I actually plugged the amp straight into the wall

The Zesto gain is 12dB, it seems perfect with this amp.   George at Zesto recommends setting the internal gain to 3 if the volume control is too sensitive 

With my other amps it was but I held off on changing it until I got the 300b the 12 dB gain is perfect 

The 300b's input sensitivity is higher so now the volume isn't as sensitive and it has a broad range of control.   It's actually perfect now.   My DAC puts out a fixed 2.5 volts ,  so at some point I  may try connecting it directly to Source 2 and use the gain as volume.  Something tells me I'll prefer the preamp in place but I want to try it.   

Fsonic,  this amp is loaded with premium parts. THAT'S why it sounds so good.  I was in the biz for a while and I know how mfg cut corners spec' ing cheap caps and resistors til they whittle down the build of materials . Not the case with a Toolshed Amp.  Inside you will find Dale Vishay, Mundorf, Clarity Cap , Jupiter Cap, Khozmo....  among others.   No corners cut here.   

 

Perhaps it’s me, I never got the impression that @oddiofyl wss suggesting that his new SET amplifier was a new innovative take on anything. Rather a very well built and implemented 300b SET. I’d venture that no “new “ take or approach is even necessary.
 

These ultra simple but time proven circuits are fantastic to listen to. Maybe it’s my inference, but I thought that is all he was implying and sharing. One hell of a good sounding amplifier. Horses for courses I imagine.

Charles

I don't mean to be pissing on your sense of Nirvana, but reality is that there is nothing new under the sun when it comes to 300B amp circuit design and darned little new under the sun with implementation. I doubt that Matt and Ben have the means to wind their own trannies. All other parts have to be purchased from known suppliers too. The beautiful casework may lend great pride in ownership (though it is not to my taste-too Brooklyn Bohemian vibe for me) but it can not make the amp sound better. Yes, a well-designed 300B SET directly heated triode amp will have the attributes you describe and I applaud you for choosing them-I would too. But again, when I see a new amp from a small company with lots of shiny chrome and by virtue of small company/capitalization size no innovation (not that any is really available) I have to say, "OK, glad you like it". I am no hypocrite-I bought an Ampsandsound Nautilus a year ago that is not dissimilar though not 300B based. But I bought it with eyes wide open that the circuit design was ancient. The guy behind the amp, Justin Webber, makes no bones about it. It (the Nautilus) is all about being so basic and so well built that it will last for generations. 

@oddiofyl 

I see that you use a balanced AC isolation transformer/conditioner. I find that balanced AC electrical power a very good choice for audio electronics.

Are you using copper or silver cables in your system?

Your speakers are quite efficient/ high sensitivity. Do you find that you have excess signal gain or is that okay? Not sure how much gain your Zesto has or the voltage output of your DAC? At one time In the distant past I had excessive system gain. So just curious.

Charles

called him a few years later and he told me he was building 300b amps .   He said this would be my last amp….  He may very well be right 

Strong possibly he may be right!

Charles

 

This amp is amazing in it’s retrieval of small details that were never sharply defined with other amps.   Reproduction of the human voice is spooky real.   I’m still getting acclimated to it and am tweaking speaker placement a little.  
 

My initial impression is that this amp nails it with respect to projecting a believable image of the performance, especially with live material.  With bad material it is somewhat forgiving and is very listenable   With great recordings it is amazing 

With great recordings I am hearing subtle things that were masked or glossed over with previous amps   My Zesto preamp has this amazing quality with transients ,  the ability to “start / stop”  like the crack of a whip.   The two pair well and have that quality along with delivering the ambiance of where it was recorded    Decay is very realistic and it has no self noise .  Very quiet for any amp never mind a tube amp  

This was a big leap of faith for me, to buy an amp blindly , with no ability to listen first.   It is generally something I never do.  I called Matt a few years ago about one of his lower powered amps   He was straight up and said it was not a good match with the speakers I had at the time.  He could have said nothing and sold me an amp that day.   I called him a few years later and he told me he was building 300b amps .   He said this would be my last amp….  He may very well be right   
 

I am going to spend some time with it and follow up after some extensive listening  

 

Yes. Charles, the two make a great pairing.  I have a set of early 50’s RCA 12ax7 and 12au7 , some holy grail stuff!  I have been holding off on using them.  I am going to get everything dialed on and maybe install those 

@oddiofyl 

I imagine that your Toolshed SET 300b to be a very good match with your current Zesto line stage, excellent synergy I’d think. Also, good move on going with the Western Electric 300b tubes.

Thanks Charles.    It sounds phenomenal and the build quality is off the charts.   I would not hesitate to do another project with Matt , he was great to work with.  He delivered exactly as promised.  It’s awesome 

Thanks , sounds incredible so far

I have no doubt that this beautiful 300b SET sounds incredible!

Congratulations to you. This is a keeper for years to come.

Charles

Just received the 300b.  It is frigging awesome .!!!!!.....   I will post some pics soon.

I unpacked her ,  made my connections and she fired right up.   

I'm using a pair of Amperex 6688 drivers, Raytheon ceramic base 274b.    Shout out to Craig Ness at Nesstone on that one !    Power tubes are Western Electric 300b.

First thing I did was switch on my tuner and did some casual listening while cleaning up the 300 pounds of Styrofoam , wood , and cardboard.   

I have only spent about an hour listening , had some Mullards in there and then decided to try the Amperex and there were much more to my liking.   

I will say this about Matt Formanek,  he is a no BS guy and delivers exactly what he promises you.   Plus he loves nothing more than building music machines 

Happy listening 

 

 

That Beauty on USAM is gone!!!  Someone will definitely be enjoying that amp soon 

Looking forward to your report. I too am awaiting a custom amp that's been in the works for almost six months now. It is a single ended KT-88 amp. I hope to have it sometime next week. Good luck!

Thanks !!!   Can't wait to fire her up.    If it sounds half as good as it looks I'll be happy !
