I can't trust a guy claiming unmeasurable -180db thd for his " famous" op amp. The 2134 is an FET design, however, for those who prefer that, and it does have a greater voltage swing possible--- it can be operated on =/-18v; the 4562 is speced only to =/-17v. Apr 21, 2008 · 【追試】lm4562 vs lm6172. ) Feb 4, 2014 · Only really better substitution for NJM4580 for example as Pre-Amp can be no less then OPA2228 or even better OPA1612, but for that -3dB less noise (and distortion) over whole audio spectrum you will have to play premium extra. My guess was right. The fastest slew rate a needle in a vinyl LP track can provide is in the region of 2-3 V/us, I seem to remember an old IEEE recommendation of 6 V/us as plenty for vinyl audio hi-fi use. May 19, 2017 · Personally I loathe the sound of the LM4562 but I haven't really given it a full chance, tailored to its characteristics. And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher voltage noise of the opamp is negligible, like here. That was the circuit where the OPA2134 sounded better. I have tried OP27,AD797,AD746, AD827,OP275,OPA627,LT1028,OPA2604,OPA2134,LM833,NE5532,SSM2139(rare but good)in various CDs, pre amps and phono stages. Of these, my favorites are OPA627,AD797 and OPA2134. LM4562 is another level altogether. Interestingly enough the OPA2134 isn't the quietest dual op amp in the P06 circuit (but still quiet in absolute terms), and the LM4562 sounds somewhat 'sterile' in comparison, if that makes any sense. Aug 22, 2007 · I always replace the NE5532 in a Rotel's phono circuit with a FET OPA2134 or OPA2604. Aug 2, 2008 · So I got a pair of LM4562 op-amp for my Zhaolu DAC three days ago. When the top cover was removed, the OPA2134 version was unaffected and the LM4562 version start to trigger at 100Hz multiples in the same way I have already shown. but blindly replacing an older LF412 in an existing piece of equipment with them is a very bad idea and the OPA637 isn't even unity gain stable, just no! I tried the LM4562 in a preamplifier instead of the original design's OPA2134. Besides a very simple simulation shows his invention very unstable . 1 9/19 2016-07-13 ACAV LM4562, Rl=2k or 600, Rs=0-150,00-140,00-130,00-120,00-110,00-100,00-90,00 0 5 10 15 20 Freq [kHz] T H D [d B] 3Vrms, Rl=2k 3Vrms, Rl=600 LM4562, Rl=2k or 600, Rs=0-150 Feb 11, 2021 · According to the TI datasheets OPA1612 has less noise than OPA1656. If you use TL072 opamps, keep resistor values above 2. #1 Choose the LM4562 (LM4562 vs NE5532): High-End Audio Quality: If your application demands the highest audio quality, low distortion, and minimal noise interference, the LM4562 is a better choice Oct 8, 2017 · Lower values can be used if the opamps can drive low impedances with minimal distortion (e. The LM4562 is especially good because it uses power efficiently and performs very well. amps and drivers yet only the LM4562 and LM4702 that are not part of these families. OPA1602 — звучание чистые высокие, воздушная середина, расширенная стерео-база, сцена ближе п… LM4562 with Rl=2k or 600 vs frequency (Datasheet) LM4562 with Rl=2k or 600 vs level (Datasheet) Audio Opamps, fact, myths and THD measurement resultsRev. 00とします。高音域、中音域、低音域、解像度、横方向の広がりについて、感じた音の差を数値化して表します。 なので主観的な測定値になります。ちなみにlm4562の音は非常に気に入っています。 AIYIMA A07 TPA3255 Amplifier Measurements and Review - LM4562 (and OPA2134) option. I like their sonic signature. I am testing the A07 with 2 different power supplies. Now the results are pretty much identical which is not what I was expecting. The OPA1642, SMT-only Muses02 vs BB OPA2134 in Topping A30 (single-ended to differential buffer) Rig includes: Topping A30 and D30, HD600s (vintage 2017) with HD650 (genuine Sennheiser replacement part) 3m cable (1. There are several versions of the NE5532. OPA2604 is one of the few op-amps having +24 -24 max supply voltage. com/v/xPj5IKtZ/file. When closed with top cover firmly, both versions behaved almost same. I think that I've just become to used to the OPA2134 'sound'. OPA2134 is more stable, as it is not too fast for Audio. I like the phono preamp (an Acoustech PH-1P) but couldn't help wondering if the LM4562 would make an improvement. LM4562 vs TL072 and NE5532 Aug 31, 2017 · Обзор безэкранного Hi-Res плеера Zishan Z2.
