Full featured balanced dac/preamp advice
Thanks to all, I appreciate the advice. I was able to purchase a hard to find Topping D90 dac/preamp here on the forum yesterday. Most reviews show it to be a great DAC but only a good preamp. If I'm disappointed in the preamp I will use it in dac only mode. If it proves a mismatch for my two channel stereo room I'll then see how it works in my headphone setup. Thanks again for all the advice, audiogon members never disappoint |
Underwood HiFi is now selling Audio GD kit. Their dac/pre has a R2R dac, and at a most reasonable price R28 (2021 version) Balanced preamp with resistor ladder DAC & 9.5wpc headphone amp $1499.00 https://www.underwoodhifi.com/products/audio-gd |
Yes that article mentioned sampling rates of 216kHz/32-bit which I've never seen anywhere else. At the bottom of the review it lists 192/24 which makes more sense and is fine with me. Also this article and anything else I've read doesn't mention the DAC chip. Or even if it is a chip or R2R although I don't think so. Almost like that information is top secret |
The Audio Alchemy DDP-1 definitely has the features. I love the two single ended and one XLR balanced inputs. Doesn't appear to be in production anymore. Maybe I could find a pre-owned unit with the power supply. Did a little research and I can't find out what dac chip is used. I know implementation is more important but it's still nice to know going in before purchase. Definitely nice to have more choices |
Thanks again for the responses. I should probably have also mentioned what I am using now, the Onkyo P-3000R preamp. Below is some information from the Onkyo website: Separate Digital/Analog Circuitry and Transformers To prevent unwanted interference, the P-3000R employs physically separate circuitry for digital and analog processing. What’s more, it also features separate transformers for digital and analog circuitry. Using this design approach helps to eliminate noise and contributes to a cleaner overall sound. Separate TI Burr-Brown DACs for L/R ChannelsHigh-quality TI Burr-Brown DACs work to optimize analog audio performance on Onkyo’s new hi-fi components. The P-3000R pre-amp sports dual 32-bit PCM1795 DACs, which support sampling rates of up to 192 kHz, display high resistance to clock jitter, and handle a 123 dB dynamic range. Although these DACs can process two-channel audio on a single chip, Onkyo employs separate chips for each stereo channel, to ensure the most accurate digital-to-analog conversion. The only reason I'm looking to upgrade is that it doesn't have balanced outputs to feed into my ATC P1 Pro amp that I recently bought here on Audiogon. I know it's a highly debated topic weather balanced will really be an improvement, but ATC highly recommends it and it's one of those things I won't know until I try it. Also I'm using an Onkyo C-7000R CD player that has the AES/EBU output that really sounds colossal when I use that connection with the P-3000R. If I were to buy something new that comes with a return policy I wouldn't be taking a great risk. Do you guys think I'm just chasing my tail with this obsession to go balanced? All opinions welcome |
I own the Bricasti M3 DAC and like it very much. "The M3 utilizes two independent linear power supplies for the analog AND digital processing to insure low noise and superior isolation". Bricasti recently released the MDx Upgrade Board. This upgrade improves the sound quality and is an example of Bricasti Customer Support. And, it sounds great. Recommended. |
A good question, however I have never heard any components that would warrant a choice on the basis of inputs and output (USB under certain circumstances) versus the sound of the component. The difference in the sound of the different components was far greater than any difference in which interconnect type would make. To optimize components... once you have the components you like then optimize for the best connections. |
Thanks for all the responses. I should have mentioned that the $2,500 price that the Bel Canto goes for is probably at the upper range of what I can spend. Unfortunately that rules out the fine suggestions except the Matrix. I could be wrong but I don't think the Matrix has the AES input. One other contender is the Newprime DAC-9. Seems like a lot of bang for the buck for around $800 but obviously not in the league as some of these others discussed |
