| Cool running, low powered power amp CODA has a lot of 'fins' and Krell 175xd gets a lot of fans (4) in the back. Won't you be bothered by them? | |
| Seeking Bookshelf Recommendations +1 Buchardt S400 Mk II which I believe it has been recommended. | |
| Music first or sound first? Without good sound, I could not enjoy the music. Hard to separate them. | |
| Cool running, low powered power amp +1 BM ahb2. class H (class A/B w/ voltage rail regulation) with 92% efficiency. Cool running device in a small form factor. Highly recommended if you are willing to make an invest. Otherwise, for $660, you could consider Smsl vmv A1 10 watt cla... | |
| Could Class D really be that good? @ricevs Thank you for the write up / advices. I pretty much agree with what you said there regarding the sound signature heavily depending on how the modules are implemented. The reason I put so much effort there investigaing measurements is bec... | |
| Could Class D really be that good? @mattw73 I’m impressed with both the Nilai Mono and Apollon St in terms of their specifications. However, I lean slightly towards the Apollon for a couple of reasons: (1) it offers 25% more reserved maximum power in both 4 and 8 ohms (despite a ... | |
| Could Class D really be that good? @atmasphere So if a class D has the same distortion signature as a good tube amp, it will sound like a good tube amp simply on that account. Agreed. But I want to emphasize, with the low 2nd HD found in these Purifi / Hypex class D, you won’t b... | |
| Could Class D really be that good? @atmasphere I was there initially but just like asr said "... The third harmonic hovers around -130 dB which again, is almost at the limit of what we can measure..." It is inaudible either at that noise floor. I am sure that, with such a low n... | |
| Could Class D really be that good? @atmasphere Just look at the harmonic spectra of the Purifi module. You’ll see a dominant second. These are freq. spretrum FFT plots for THD and IMD from the published Purifi 1ET400A data sheet. For IMD, all spikes are beyond the audible freq. ... | |
| Could Class D really be that good? @atmasphere Thank you for the very helpful information. I recalled someone asking / commenting about the musicality and I have examined all the ASR measurements but could not find one appropriate to be an indicator. After a brief search I was onl... | |
| Could Class D really be that good? I could not agree more, @pindac. Such a ’bybrid’ amplification could be even better on a active crossover system. A good (mini)DSP could easily lead us there, which will be more convenient than the passive crossover system. A lot of class A / tube... | |
| Could Class D really be that good? @pindac Please forward the link once you have it. I also dived into the DIY project based on Purifi 1ET400A and Hypex NC400. I am particularly interested in the hybrid one with tube buffer made by VTV. Although its price tag is relatively pricier,... | |
| Could Class D really be that good? @pindac Truly amazing stuff that Audiophonics has accomplished. Built on Purifi/Hypex modules/ps, the HPA S400-ET has been highly praised by ASR based on its excellent measurements. The compact size version, LPA S400-ET, has almost identical specs... | |
| Could Class D really be that good? @eddnog I got in and pledged for two Monos with two 48v/5a PSUs. I felt fortunate making the last-minute decision and went with two independent PSUs because later today I saw this https://www.youtube.com/watch?v=wjWVSFCR5MI where the host experie... | |
| Could Class D really be that good? @eddnog I am a bit lenient. Could always wait until June from Amazon. I plan to use a 48v/10a psu to power them with a splitter cable, primarily to save space. Do you think will that compromise SQ in any way? |
