I am confused - I see/hear the name DAC-7 or sometimes TDA1547(DAC7) then there is the SAA 7350A; GP; GP(A) etc.
Then there is the SAA 7350 AGP with the SM5840AP as used in My Tascam Pro CD401(11), which I am told is one of the best sounding Pro CD Players compared with even today's newer models.
Also where does my unused TEAC D-T1 (2xTDA1547) fit in. The rest of the system Quad 44/606 plus Cambridge R50 (Falcon Acoustics x'over upgrade & re-wire)

"DAC7" is a chipset, not a single chip. It refers to the SAA7350 & TDA1547 used together. The SAA7350 is used for the front end of the bitstream process, with the TDA1547 doing the final d/a conversion, and active i/v if you choose to use it's internal opamps.
That's great thanks. Just one further clarification, if I may.
In the article I am reading, the TEAC D-T1 DAC mentions the two together (x2), but the TASCAM CD 401(11) seems to specify only one SAA7350AGP, but makes no mention of the TD1547 Is this an omission or a misprint?

Quite obviously this is my kit I am talking about. The article says that the DAC7 is a much better solution than the TDA1541A as it is designed to operate at higher levels and reduces the risk of clipping and distortion.
I have inserted the TEAC D1-DAC into the CD path, which means I have lost the higher quality output of the balanced XLR in favour of the Digital Co-Ax thereby by-passing the TASCAM internal DAC. The first thing I noticed was an increase in volume and a much bigger soundstage, however the musicality (Hi-Fi) realism, ambience had all suffered quite significantly. Instrumental sibilants were often no longer noticeable, or, if there, did not have the same spine tingling effect. A return to the original configuration of XLR into Amp once more provided the spine tingling subtleties, but it was noticeable that the soundstage was distant and thin and not improved simply turning up the volume.
Clearly I need something changing or modifying - But I don't know what.
Any ideas gratefully received.

The SAA7350 can be used without the TDA1547 - presumably that's what they've done in the TASCAM.
While I have some DAC7 chips myself I very much doubt any DAC7 implementation will be better than TDA1541A. Some numbers might be superior but that would be all.

Where to go next.....?
OK so I now know what I currently have available - a stand alone consumer DAC with two of everything, which sounds authoritative with detail but little finesse. -or- an integrated on board DAC, which has all the sweet detail, but lacks authority.
There is no doubt that using the balanced XLR, direct, does provide the sweetest or cleanest sound, operating at a volume level of 10/22 BUT using the separate external DAC with standard RCA connections gives a fuller less detailed sound operating at 15/22 volume.
Problem: How to increase the output level (NOT the Volume) of the TASCAM on-board DAC.
OR: How to improve the Fidelity of the TEAC T1 DAC
Or you could recommend a different unit(s).
In anticipation, Stu.
