Title: New Zen Triode Preamp / OTL headphone amp Post by Steve Deckert on 06/20/06 at 01:14:23 It's done! :D The new CSP2 preamp / OTL headphone amp is on the web site and ready to order. An introductory price of $695. is listed. This price is likely to be very brief. If there was an MSRP it would be $1349.00  Design notes are also posted on the site. |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by nubz69 on 06/21/06 at 05:48:56 Is there any way to have my current csp upgraded? |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by 9anda1f on 06/21/06 at 15:56:43 Placed my order for the CSP2 this morning! It had all the features I've been looking for: Decware (!) SET Mono out for sub Headphone jack Dual Inputs Plus more: OTL for the headphone out (wow) Stuff to tweak (top mounted pots, tube rolling) Unbeatable price! Looks awesome! It will be replacing my Audcom AP-110 tube pre. Guess this also means I'll have to get some wood bases for my SE-84C's (to keep up appearances!) I'm pretty excited, can you tell? :D |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by RFZ_Quest on 06/22/06 at 01:15:33 I just ordered the Select Zen Preamp model CSP2 yesterday afternoon and will get a chance to hear this unit in about 4 to 5 weeks. I was thinking about purchasing a set of Grado model 650 headphones. After discussing various types including this one, I will follow Steve's recommendation and go with the following choice which brings spectacular performance at an affordable price!  designed for critical music and sound monitoring in an open environment. It has a bass-reflex system to give low-frequency response down to 5 Hz and is equalized to the diffuse sound field. The weight of the diaphragm and moving coil of this headphone is approx. 20% compared to other current models. As a result, the DT 770 PRO offers similar pulse characteristics as electrostatic headphones. The cushion systems and light weight allow the DT 770 PRO to be used in complete comfort for long periods. Application The transducers are fitted to adjustable yokes, which should be positioned to fully enclose the ear. This will provide the optimum ear/speaker position for accurate sound monitoring. The cord is terminated with a high-quality gold plated mini-jack and a 1/4" stereo jack adapter. Professional users should note that it is recommended practice that headphones are issued on an individual user basis to preclude any possible health risks. Maintenance As with any equipment which will be used in close proximity to sensitive areas of the body, it is essential that the ear-pads and head-band are kept clean. Use a damp cloth for cleaning using warm water only taking care not to allow any water drops into the transducers. Should it become necessary to replace the ear-pads or the head-band cushion, refer to “Spares and Accessories”. Safety When plugging your headphones into an amplifier, please make sure that the volume control is set at minimum and is adjusted after they have been put on. It is common phenomenon to listen to music through headphones at high levels. The very low levels of distortion present within the DT 770 PRO can make the listening levels higher than is perceived and we would like to warn you of this so that you are able to enjoy these headphones for many years without damage to your ears.

I think it will be possible to upgrade a CSP to the new circuit. Having yet to do one, I'm not sure what the actual cost would be. My guess is somewhere between 200~300 bucks. Steve |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by veryoldcat on 06/22/06 at 05:11:46 Very cool... I'm certain upgrades are no picnic for the manufacturer/Decware, and am grateful for the possibility. Karl |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by proud_indian on 06/22/06 at 09:43:05 Ok Guys... help out a headphone idiot. Steve mentiones time an again in his article about ' in your head' stuff. I have not experimented with headphones, but always thought that you could not experience a sound stage. He also mentiones about ' being there in the venue' . So, what do you hear in a pair of headphones which are linked to a great amp? Can somebody write their experience. Thanks shreekant :) |

I second that and would be interested in upgrading my CSP to a version2 if it was financially workable. After UK tax and postage, I guess the CSP2 is close to (correction, $980) so sending my CSP1 to Steve would be worthwhile. Just the tax savings alone (since it's for "repairs") would pay for the 2 way trip. |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by Mr Content on 06/23/06 at 07:22:16 Yes I would be in for an upgrade. Just let us know when its available. Thanks Steve Mr C |

Steve, When you mention this upgrade, what would it include? New features, new box, mono out, headphone jack? The new design concept fits exactly the way I want to go in audio. I eventually want to match up a pair of Nibbelins to the WO32 I am building so an upgrade of my CS to this new CSP2 should provide a seamless integration. On the other hand, a new CSP2 and a new CSZ matched with my old CS and CSP would provide for a superb 4.1 home theatre mix. ??? |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by Rocket_Ronny on 06/26/06 at 23:18:14 Now this is a piece I would love to pull the trigger on. Not so much for the pre, as I am sure it is great, but for headphone amp. Can't though, as I found we owe double for our home taxes. When we moved we thought the lawyer said to ignore the tax bill as it was taken care of in the purchase of the home. Well, we were wrong about that. She was talking about the taxes on our old home we sold. So now we have to cough up $4,000.00 instead of $2,000.00. Cough, cough. Plus I just bought a Metric Halo ULN-2 DSP computer audio interface box. Timing is everything in life I guess. Interesting headphone recommendation. From what I have read about them people find them bass heavy. As in very bass heavy. Great for disco, tecno, bass freaks, but not for the mainstream. Let us know what you think of them when you get them. Rocket_pauper_Ronny |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by boead on 06/29/06 at 13:20:59 Rocket_Man_Ronny, I hope fabulous wasn’t to strong of a word but I do LOVE that word. I say fabulous because in the sub $500 price range for Headphones I have always found the Sennheiser 580/600/650’s to be the most enjoyable models. However, the AKG 501 just have a great sound stage, so NOT the in your head sound and coupled with a great headphone amp it makes for an amazing headphone without spending $1000 or more on electrostats. Unfortunately they just have NO bass and it kills me because I just can’t listen to them. The 701’s have a very similar euphoric soundstage and they have bass! |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by Rocket_Ronny on 06/29/06 at 14:26:07 Thanks for that Boed. So what's the main difference between the Sens 580 and the 701s? I have a couple of pairs of the 580s. Rocket_still rooten and a tooten_Ronny |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by Giorgino on 06/29/06 at 23:34:58 Slightly OT - Anyone with thoughts on the Stax SRS-2050 II? |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by Grant Robinson on 07/19/06 at 03:28:08 Slightly BOT (Back on topik) I picked up the CSP2 prototype from audiogon and plugged in the unit this evening. Well built and a very nice layout for the new format. The unit at first impression adds some sparkle to the top end and more weight to lower notes. This was tested with a Taboo and Dec685 but with a Zbox out of the chain. I believe it's a keeper... Cheers Grant |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by MAC -SteveH on 07/21/06 at 00:02:06 My Official NEW CSP2 is on its way!! I should have it by Monday. YEA!!!!!!!!!!!!!!!!!! I will keep you guys posted |

Title: Re: New Zen Triode Preamp / OTL headphone amp Post by 9anda1f on 08/08/06 at 01:44:32 IT'S HERE! My new CSP2 just arrived! It's cool...but warming up nicely! First, very first impression: Did the sequenced warm-up/plug-in procedure...all is well. Pre-amp that was removed from set-up was the Audcom AP-110. Everything plugged in, but disc not engaged, ran volume control from 0 to "10"...ABSOLUTELY NO NOISE AT ALL. It took away the slight, but noticeable hum that's always been there. WOW! Here we go! :D :D :D :)9anda1f :) |
