Hi Paddy,
Mine is also a Mark I. I contacted Trichord a while back and they wanted £200 to upgrade it to a Mark II. They did say it was a better upgrade than the Dino+ PSU and of course you could also add the better PSU to the Mark II at a later date.
I have a Michell Gyrodec SE with RB300 (Origin Live modified) and an Ortofon KontraPunkt C cartridge.
What are you going to run through the Trichord?
Cheers
Steve

Cool, be interested in your thoughts on the Dino when you have had chance to play with it for a while.
Cheers

Yeah Should be a good listen got to be better than my musical fidelity xlps phono stage i have had for 9yrs. The xlps is still a good phono stage though clarity wise, just think the sumiko needs a better phono stage to let it shine. paddy |

Stevieg I have heard there is not much difference between the mk1 and 2 on various forums on the net, i think the dino+ psu should be a better upgrade, i am going to put 3 oak cones underneath mine for a more stable sound (why do you think a camera tripod has 3 feet). paddy |

why do you think a camera tripod has 3 feet? Cost saving.... it doesn't need to "walk" so (ideally) one foot would be the optimum.... 3 feet is the minimum it needs to "stand up"  Does the job..... I, myself, prefer a 400 feet camera stand, they are much more stable but take a bit longer to set up  |

3 legs are the minimum for stability but also they are the most flexible - there is no risk of wobble etc when setting them up. This is an old maths thing which some greek bloke probably explained but which is pretty evident from War of the Worlds.

Freddy I think it was pythagorus or someone like that. 3 legs are more stable because it is less prone to vector forces (micro rocking etc) were as 4 legs are going to rock on 4 corners (4 triangles inside the square/oblong etc) the triangle is more stable shape (like the pyramids). paddy |

Got the dino today and plugged it in. Only listened for a couple of hours so i know it wont have warmed up properly, sounds better than the xlps (more detail etc) but i am unsure what capacatance to set. I have a sumiko bluepoint no2 mc cart, the output voltage is 2.5mv, the load impedence is 47k ohms, so i set the dino dip switch to low mm which is 2-3 mv but the load impedence has 2 options - mm 47 k ohms 100pf or mc 47 k ohms 1.1nf and i am not to sure which one to choose. I have listened to both settings, the 47k ohm 100pf sounds a bit brighter and the 47k ohm 1.1nf sounds slightly duller, now the info on the sumiko pamflet that come with the cart says - If your receiver or pre amp has capacitance loading capabilities, a sumiko high output moving coil cartridge should be loaded with a value no higher than 200pf and ideally below 100pf. So would the 100pf setting be the best, any help would be appreciated on this matter. paddy |

Paddy
Use 100pF for MM, and most high output MC cartridges,
unless the cartridge maufacturer specifies otherwise.
Alex.

Thanks alex and frans for the info.  I will leave it on the 47k ohm / 100pf setting paddy |

The Hart Audio Chiara headphone amp has had rave reviews elsewhere on this site and I highly recommend the company's phono stage with matching power supply. I have had a number of quality phono stages and this blows them all away as far as I am concerned. I read a review of it that said Hart seemed to sell their products based on part count without any margin for design etc. I would be interested to see if Mike could make the same level of improvements to the phono stage as he managed with the Chiara. I have been searching the web for a Hart Phono amp and psu. If I could at least get hold of the psus it would be great. Can anyone help please. |

Arriving on the scene a bit late but:
I've had the Sonneteer Sedley (non-usb) phono stage for quite a while now....and it's been more than excellent enough partnered with my Audio Note TT1/Arm2/IQ-2 turntable system. Lots of settings on the back for each channel via exposed dip switches, making it easy to bring out the music on challenged LP's or calm down some of the older pressings. It is a full size piece of equipment that resides on the base of a rack that gives it good support and isolation. It accepts the Audio Note AN-V interconnects very tightly and sends the phono signals to my Croft linestage via MIT-330II interconnects. The MIT's are fine, excellent actually, here.
Not many reviews in English for the Sedley since 1999, but it seems to garner raves from the Japanese press, even recently. Really a great sounding phono pre...in all respects. J

I took a couple of pics of this set up with my older Sony digital camera and....I'll try to get them uploaded onto RG....XTRProf. It's about time I show my predeliction for (obscure) British HiFi equipment. I've never coddled up to American stuff.
So, I'll see how far my limited knowledge of uploading gets me. J
