These can be setup to provide about a 15k input impedance (a bit low for the Clarinet on a long cable run, but doable nonetheless). What I've done is purchase some Sowter 8920 transformers. I, too, want to use my Clarinet as a preamp but I need a balanced output. I have a rather strange application where I run two amplifiers out of phase (I have direct-drive Acoustats, with one amp powering the front stators and another powering the rear stators with a 180 degrees out-of-phase signal). In other words, you don't get the noise rejection you get by summing up the signal at the input of the preamp. I look forward to hearing what you think when you get it back.Dualing Clarinets would be very cool! The problem with that topology is that it doesn't take advantage of the differential balanced input. I am prepared to believe the new ivy is better than the one I have, but I doubt it, if it was they would have to describe the one I have as broken by comparison.Īgain, all IMHO, but I am certain of what I think (as it may be obvious from what I have written). Thinking about it as I write this, there is no question, I prefer the valve output stage over the Modwrite. The Modwrite is not as tight, not as revealing, but is a bit more spacious. The valve output stage does detail, is tight, has great bass control and detail, is very dynamic, and has great space between instruments. The Modwrite is equally as good as the Valve output stage, but slightly different, I think I prefer the Valve output stage, but the differences are small and subtle and I would be happy with either, Ian liked the valve output stage, but not enough to worry about replacing the transporter. The valve output stage is vastly better than the Ivy, simple and obvious. The system was digital dource, Modwrite transporter, DAC, either yours (Valve and Ivy) or the transporter, Amp belCanto 845 SET, Quad 989 speakers. Bear in mind this is only my view, you may think differently, though Ian thought much the same. ![]() It was interesting, and matches what I thought at home. "Back from comparing the DAC to the fully modified Modwrite transporter (with flash Japanese valves in the output stage). In Nicks words 'one of the best dacs he has heard'.Īt this time of writing Nick was comparing this to my old buffalo board with the first generation ivy, this was before my new buffalo II and ivy 3 was shipped to me. ![]() This is a modified version of logitechs transporter dac (see pic below). Nick was lucky enough to be able to compare this dac to a modified 'modwrite transporter'. I really can't fault it, i just prefer the slightly richer valve sound. I find it makes the ivy seem a little sterile in comparison, however the ivy does have great sense of separation within the instruments. It's nice to be able to swap between a valve and the ivy 3 output. I find this especially good when paired with a slee solo as that amp is very detailed. I find the sound of the buffalo with the valve output really helps to add more 'weight' and a 'thickness' to the sound. Its a nice combination being able to have the solidstate with the valve output. I have to say, the b22 does always sound great. It just sounded so open, it was incredible. It sounded nice with all of them, but for me my favourite was the aikido and the buffalo with valve output. I have so far managed to hear it with my b22, modded x-can v3, graham slee solo, aikido valve amp, millet max and a modded jaycar amp. Since I also have a balanced β22, I'd love to hear some quick impressions of the DAC and amp synergy, though I can imagine it to be first class. Originally Posted by swt61 /img/forum/go_quote.gif I also use the placid and placid bi polar boards to power the buffalo and ivy 3. I also added in the spdif mux board for multiple inputs and Nick came up with a nice little switch board that remembers the state in which the dac was last used (i.e. We went for a set of 6h6p russian valves and made custom switch relay boards to control the output selection to use either the valves or ivy 3. It uses some nice Sowter output transformers and custom Canterbury designed transformer to power the valves. Anyway we managed to create this dac pictured below (sorry about the crappy pics). ![]() I am a lover of valves and none of my dacs use valve outputs. It has been a joint effort (although the brains behind this build was my mate Nick) to build a dac that i can use as my main dac with a switchable output using a custom valve output stage and the ivy 3.Īfter being one of the lucky few to bag one of the new dacs on the first round i was keen to see what we could do with the output stage (not that there is anything wrong with the ivy 3). Hi guys, over the past few months i have been working on a project with a friend to build a valve output for my buffalo II dac.
