I just have a couple of questions about the Taboo upgrades and believe starting here is a wise decision.

 

 

From Decware website:

 

CUSTOM OPTIONS

Since the chassis was designed to accommodate additional jacks and even another tube if needed, the following options are available:

  • Choose between the black figured base or the contemporary walnut - FREE
  • Choose from a variety of alternate hardwoods - add $50
  • Stepped attenuator - add $250
  • V-Caps - add $200
  • Headphone jack for Planar Magnetic Ear Phones - add $100

 

 

- For those who have the V-Cap upgrade, how many caps in total and what are their values?

 

- Why does the output jack cost $100 for Ortho users? 

 

 

So I'm gonna pull the trigger soon.  Any advice on what other options to get or not to get?

Will be using vinyl as the only source so no DAC is needed in this setup.  Cans are LCD-2

Don't have vcaps.  There is no headphone jack unless you pay for the mod.  It's not a special headphone jack specifically for planars if that's what you are thinking.  The low output impedence makes it most suitable for planar magnetics, combined with the fact htat if you used high sensitivity headphones who knows what might happen.  I'm sure it's fine but you probably can't turn the volume up very much.  With my HE-500, I generally listen with the volume at around 8 or 9oclock, and the max I go is 12oclock.  

 

Anyway, it costs 100$ because it takes extra labor.  If you're going to be using speakers as well, make sure to email them and ask for a switch between speakers and headphones.  Apparently they don't default to this.  Some seem to have the switch and some don't.  Mine does not have the switch and while it's not that bad to unplug and plug in my speakers when needed, a switch would make my life a lot easier.

I talked with Steve Deckert when I ordered and he is very confident in the way the TABOO sounds with his caps.  I ordered the VCAPS just because.  I hope I live long enough for them to break in.  The way I see things, the biggest upgrade for the TABOO is the CSP2+.  I think the preamp will help out my Bob Latino SV-120 Dynaco amp too.  I am looking forward to hearing the difference between my two amps.  My LCD2's are in the mail as we speak.  Glad I was able to get the travel case with the headphone order vice the lacquered case.

Still curious about the values of the V-Caps and how many there are.  What are the stock caps anyway?  If they're nice I won't bother with the upgrade.

 

Congrats on the Audez'e smily_headphones1.gif

What is the output impedance (headphone use)?  I read on a different thread that the Taboo operates at 2W into 60 ohms for the LCD-2.  Is this correct?

Partial answer, which may or may not help, since this is really outside my realm of knowledge. 

 

So for what is may be worth, there's 1 capacitor in the signal path.  

 

Stock is GE military polypropylene film, the upgrade Mundorfs, best I can figure out the silver / oil.

Hi again vinyl addict!

 

See this post. Summarized there is my erroneous calculation of 960mW into 50 ohms together with Chris J's correction based on the Taboo schematic, (edit) which suggests a transformer output impedance of six ohms.

 

2.39W into 50 ohms equates to easily 2W into 60 ohms I would think.

Is it ok to start up a CSP2+ with no headphones plugged in and plug and unplug while on?  I had a Amperex bugle boy arc and I don't want to mess up my HD650s if it happens again.

post #457 of 1212

I stumbled upon an older Taboo manual today.  May not be applicable to headphones but interesting nonetheless.

 

 
"BEFORE POWERING UP
 
Be sure that you always have speakers connected to this or any tube amp before turning
it on. Tube amps are typically the opposite of solid state in that you can short the speaker
wires together and nothing bad will happen."
 

 

So far so good, I've done both, powering up with and without headphones to the Taboo.

Tube amps with output transformers must have a load. That's why when dealers warm them up without speakers, they put a resistor load. If there's no load, there is a impedance mismatch.

I start mine all the time without the headphones plugged in and have zero issues

For headphone tube amps, the general safety rule (even for for OTL amps such as CSP2+) is that the volume knob (in front of the CSP2+) should always be set to the minimum (i.e. ZERO volume) before you make any changes such as turning your amp on and off or plugging in and unplugging headphones.

In that way, you essentially have all your bases covered.

 

For speaker tube amps (e.g. Taboo), they should always be subjected to a load either from the speakers or from a special resistor connected to the speaker terminals. Otherwise the transformers are likely to blow. Even if they don't blow, the longevity of the tube amp will be affected.

post #461 of 1212

There is an important difference here.  The CSP-2 is both OTL, and a pre-amp.  It doesn't need a load connected.  You can leave it without headphones plugged in forever.  It's designed that way.

 

The Taboo (or Mini-Toril) are output transformer coupled and do require a load to be connected.

post #462 of 1212
This may be another good reason to have resistors connected to the Taboo speaker taps so there is always a load.

Afternoon everyone!

My new decware trap speakers arrived today and will be using my mini torii to run them.  I love the size and the sound is very nice with only about a few hours of burn in,  excited to see how these develop :P

So below I posted my old speaker setup and also the new on with the real trap speakers :P

Fantastic and congrats.  Out of curiosity from driver install to shipping how long was the wait?  Ok, I confess it's not curiosity, it's impatience.  I want my DM945s NOW!!

Hey there,

 

If I remember rightly it was within the same week once driver was installed to when it was shipped. Either way its very soon lol...Love to hear your impressions on the dm945

 

have a good one
